6. Show HN: Flexible Internet Treasure Map (FITM)
URL: https://fitm.online/
Author: julianlk
Description: Hey hackers,
I’m excited to share this and think at least a few of you might have good fun with it.
The Flexible Internet Treasure Map (FITM) is a bit like oldschool del.icio.us and StumbleUpon. It’s all about sharing and organizing the best of the Internet using a folksonomy link tagging system while allowing hierarchical sorting based on user ratings and some other filtration methods to quickly find what you want and avoid what you don’t. It’s not a web crawler—links are added manually by humans. There’s an /about page with more details if you’re interested.
I think it could be both useful for targeted searches and fun for non-specific rabbit-holing.
This idea comes from a craving for more nuanced online sources and more reliably valuable recommendations than what search engines have been able to offer recently. I see a lot of users on HN and other sites commenting with similar distaste for the blandness of the modern Internet, reminiscing about what it was like in the 90s and 2000s. I didn’t see the 90s Internet, but growing up immersed in the 2000s Internet was magical. (Though also occasionally horrifying as a kid without much sense for what to steer clear of.) It was alive with creative surprises. I want to help bring back that Internet, especially for young people today who don’t know what they’re missing.
I’ve added a handful of links that I think are pretty cool which hopefully will be new and enjoyable for some of you. Some are admittedly sourced from browsing HN, and HN itself is on there, so maybe those won’t be so new. But I’m most eager to see what YOU all think are the best hidden gems out there on the Internet.
Happy treasure hunting!

…and as a quick disclaimer, I am NOT the best dev here or even close. This is actually my first project that I think might not completely suck. But it certainly may have some bugs. When you find one, please shoot an email to [email protected] and I’ll work on getting it fixed ASAP.

10. Show HN: KeyRunner – Secure API Client with Encryption and Secrets Scanning
URL: https://marketplace.visualstudio.com/items?itemName=KeyRunner.keyrunner
Author: mysterious9247
Description: Hey HN,
We built an API client called “KeyRunner” that focuses on security while offering all the core features for free. If you are tired of API clients that charge for basic functionality this might be worth a look.
KeyRunner’s Core & Free Features:
1) No Signup or Login required 2) VS Code Extension & Desktop Apps 3) Local Storage & Local Execution: Everything runs locally, with no cloud sync. 4) Run Unlimited Collections: No limits on running collections, unlike many tools that restrict this. 5) Mock Servers : No Limits on Mock servers 6) Encrypted Environment Variables 7) Scriptless Testing & Request Chaining: Create and test your API flows without needing to write scripts. 8) GIT Integration 9) Secrets Scanner: Automatically scan for sensitive data leaks. 10) Secret Stores Integration : Hashicorp Vault, AWS Secret manager, Google Secret Manager, Azure Key Vault
Why We Built KeyRunner: We noticed many API clients lock basic features behind a paywall or make you deal with unnecessary cloud sync. KeyRunner gives you everything you need for free, with no sign-up required and all the essential features run locally. Only advanced enterprise features (which small teams probably wont need) are paid.
Business Model: We are focused on security first and not putting basic, needed features behind a paywall. The priority is giving developers the tools they need to secure their data without hidden costs. Our paid plan is only for advanced features meant for larger teams or enterprises.
Would love to hear your feedback and suggestions. I am happy to answer any questions!

13. Show HN: Knowledge Table – Explainable multi-document extraction
URL: https://github.com/whyhow-ai/knowledge-table
Author: tomsmoker
Description: hi HN,
We’ve just open-sourced knowledge table, a tool designed to simplify extracting and exploring structured data from unstructured documents.
We built it internally to help solve some of the structured data problems we work on, and kept getting questions about it when we used it in demos. A lot of it was motivated by the frustration of zero-shot multi-document retrieval, as well as the need for non-technical domain experts to have an interface they’re familiar with. We found that inserting a tabular intermediary step for structured data construction in your backend RAG system improved accuracy and consistency, and was immediately explainable (and critiquable) by domain experts.
It’s built with react and fastapi, all dockerized. We’re going to consistently contribute to this, mostly integrations with some feature extensions we learn from customer work. Future work is outlined in the readme and roadmap.
key features:
- natural language interface for data extraction
- customizable extraction rules
- chunk linking for data traceability
- spreadsheet-like interface for familiarity
- extensible backend for developers
This is intended to be a community project, and we’re looking for feedback and contributions, but we’ll be working on it regardless as customers use it. We’re particularly interested in hearing about potential use cases, feature ideas, and code contributions. Suggestions and critiques welcome.

15. Show HN: GPT Circuits – Mapping the inner workings of simple LLMs
URL: https://peterlai.github.io/gpt-mri/
Author: peterlai
Description: I’ve built an app that extracts interpretable ‘circuits’ from models using the GPT-2 architecture. These circuits reveal how specific inputs influence the probabilities of the next token in a sequence.
While some tutorials present theoretical examples of how feedforward layers and attention heads may produce predictions, this app provides concrete examples of how information flows through an LLM. You can see, for example, the formation of features that search for simple grammatical patterns and trace their construction back to the use of more primitive features.
Feel free to reach out with feedback. I’d love to work with others on scaling out the size of the model that circuits can be extracted from.

18. Show HN: Presidential polling with instant electoral results
Author: jkarneges
Description: Hi HN!
This is an experiment with low-friction, “fearless”, Internet-based polling. There is no authentication, only a captcha and restriction to US IP addresses. Congressional district is detected automatically. Selections can be changed at any time until the poll closes, kind of like a presidential caucus. Just tap to select. Tap again to change.
I built this after pondering about how polling (or even voting) could be improved through technology. Yes, digital voting is a tough space with trust issues. Maybe there are practical, partial solutions.
This is my third post. Earlier submissions didn’t perform well, probably because politics is a sensitive subject. However, this project is not political. It is about tech and process. I believe it’s an appropriate submission for HN and it ought to be interesting no matter your political leaning. Hopefully with this better framing there can be better discussion.
Another way of looking at it: if the poll results bother you, think about how improving polling/voting generally might help your cause.
Here are some topics to guide constructive discussion:
* Internet-based polling. Can we make this a routine thing? Would it be worthwhile? Abuse prevention?
* Internet-based voting. About time or never gonna happen?
* Augmenting the voting experience. We don’t have ranked choice voting, but maybe it could be simulated in advance of an election. Maybe an organization could act as a delivery agent for mail-in votes.
* The tech stack. This project uses a combination of boring (Django+Postgres) and shiny (Fastly edge pub/sub, captcha, etc). The database ought to be able to handle a few million participants. To get to a few hundred million I’d probably add more PG nodes and shard. Curious what others think about the database options for accurate+fast counting.
* Have fun with it! This isn’t a real election. If you want to VPN to an empty state to claim a bunch of electoral votes, go for it. I hope with enough participants the results would be mostly representative, though.
The poll will run every Monday afternoon/evening until Election Day. It’s designed to withstand a good bit of traffic so feel free to share it.

19. Show HN: macOS Realtime Subtitles with Local Whisper Turbo
URL: https://apps.apple.com/ae/app/subtitly-live-meet-captions/id6673901809?mt=12
Author: vovaflames
Description: I have hearing issues and I do not always understand what people are saying to me.
Launch of Whisper Large v3 Turbo helped me to create an app with realtime, reliable and local subtitles and translations for Mac. Whisper large v3 have support of 70+ languages, so it will work pretty much for everyone globally. Subtitles (or Translations) will be in Mac’s Notch so on call you will always look into the camera.
+ Due to Apple’s Silicon Chips it is possible to do it offline, so it is good for both privacy reasons and offline access.
App will be available on 21st of October. It will be free for first 20 minutes to prove value.

Description: Hey everyone,
I have been trying to build a terminal based app for sometime now and this is an attempt at trying to build a chess app that one can play right inside terminal.
I was inspired by chess-tui[1] which is a rust based project and was looking to build something similar using python. Luckily I stumbled upon textual[2] recently and it made my task of building this far more easier than I thought.

22. Show HN: PostalAgent – Send Postcards online by circling areas on a Google Map
Author: AutoAPI
Description: Hey HN, I just launched https://PostalAgent.com, a site that lets you easily send highly targeted postcards to specific neighborhoods.
I originally built this site 5 years ago but shut it down when my full time engineering job became too demanding, but recently I did a full rewrite with many new features.
To start you can select an area using a City, State, or even by circling specific areas on a Google Map. Then, you can refine your results and filter on specific demographics, like household income, home value, rental status, etc
You can also search for Businesses rather than consumers, and even filter by franchise type, presence of email, IRS tax code, Franchise Type, etc.
I was able to get a few clients signed up very quickly, mostly home services type businesses and real estate agents, but I think it could be used by many types of businesses. I have a few customers that are only using the mailing list feature without sending postcards, likely for cold email or other marketing outreach.
I’m looking for a bit of feedback from the community.

URL: https://legadoculinario.com.br/
Author: victor_bram
Description: I’m Victor, and I just launched Legado Culinário, a platform that helps families create digital cookbooks with all their cherished recipes and stories. It allows anyone to register their family recipes, add photos, and share them in a simple and organized way.
This project came to life because I wanted a way to preserve the culinary traditions and memories that make family gatherings so special. With just a one-time payment, users can have lifetime access to their digital cookbook, making it a lasting legacy for generations to come.
I built this platform in just a week, inspired by the positive response to another project I launched recently. I’m focusing on making this accessible and easy to use, especially for those who value keeping family traditions alive.
Would love to hear your thoughts and feedback on this!

25. Show HN: Trocatalent – Building a skill exchange platform for solopreneurs
URL: https://www.trocatalent.com/en
Author: ducdeswin
Description: Hi there,
I’m developing Trocatalent (https://www.trocatalent.com), a platform aimed at enabling solopreneurs to exchange skills without monetary transactions. The idea was born from my own experiences as a solo founder, realizing how challenging it can be to access diverse skills on a bootstrap budget.
Current features:
- Skill categorization system: We’ve developed a comprehensive taxonomy of business-related skills, allowing for precise matching.
- Basic matching algorithm: Currently uses skill categories, user-reported expertise levels, and project requirements to suggest potential matches.
- Reputation system: Users rate each other post-exchange, building a trust score over time.
- Escrow-inspired exchange process: To ensure fair exchanges, we’ve implemented a simple system where both parties must mark tasks as complete before the exchange is finalized.
Tech stack:
- Backend: Node.js with Express
- Frontend: React with Next.js
- Database: Mongodb
Challenges and future plans:
- Improving the matching algorithm: We’re exploring machine learning techniques to enhance match quality based on successful past exchanges.
- Implementing a blockchain-inspired ledger: To create an immutable record of skill exchanges and reputation scores.
- Scaling concerns: As the user base grows, we need to ensure the platform can handle increased matching complexity.
- Community building: Developing features to foster a supportive community of solopreneurs.
- Verification system: Working on ways to verify user skills without creating excessive barriers to entry.
We’re in the early stages and actively seeking feedback. Some questions for the HN community:
1. As a solopreneur or developer, what features would make this platform valuable to you?
- Any suggestions on tackling the challenge of fair skill valuation in non-monetary exchanges?
- Thoughts on implementing a decentralized aspect to the platform? Is blockchain overkill for our use case?
- Ideas on how to validate skills effectively without resorting to traditional certifications?
I’m excited to hear your thoughts and open to any questions about the development process or the challenges we’re facing. Your insights could really shape the future of Trocatalent.

26. Show HN: I built an open source, simple, and affordable startup hiring platform
URL: https://www.startblock.me/
Author: jacobtt21
Description: Hi everyone,
inspired by a tweet lamenting how expensive and overly complicated hiring platforms are, for startups, i built StartBlock.
it’s delightfully simple to use, super affordable ($10 / mo), and open source. Using my experience as an engineer at a YC-backed company that was hiring, i figured out pain points that startups faced while hiring and made sure that StartBlock addressed them as opposed to adding a whole bunch of features that don’t serve any sort of real purpose (or claim to serve a purpose but is really just an excuse to add AI).
I have a demo up and a free 1 month trial so I would love to hear y’alls thoughts!
thanks and happy hiring!

30. Show HN: Okbookmarks – A Search focussed Bookmark Manager
Author: purple_wow
Description: Hi,
The inspiration behind building this tool
Instance 1: I wanted to create a promotional image for one of my apps. I had previously bookmarked a site that offered free iPhone mockups, but I had to browse through all the URLs saved in my browser’s “design” folder to find it.
Instance 2:
While working on https://frogment.app, I needed a WYSIWYG editor with a specific feature. I remembered I had starred a GitHub repository that matched my needs exactly, as described in its README. However, when I needed it most, I couldn’t locate it and ended up Googling hard just to find that same repository.
This led me to create Okbookmarks, a simple tool designed to make bookmarks searchable. It uses chromedp to crawl URLs, converts them to markdown, and indexes them for easy search.
Built with Golang and SvelteKit, it’s hosted on a modest Fly.io machine.
I’d love your feedback on features you’d like to see or any improvements that would make it more useful, or if you think it’s a solution worth pursuing.
If nothing else, I plan to open-source it soon.
I have also added roadmap items in the website

Author: dotspencer
Description: A few times a week I find myself turning to diff checker websites to compare snippets of text or JSON, but I’ve always found their UIs clunky or unnecessarily complicated. I set out to build a simpler option with a pleasing UI.
Features that mattered to me:
- Client-side only diff that never leaves the browser
- Clear indicator when text is identical
- Text input preserved in localstorage so it persists between refreshes
- Ability to show only changed lines for comparing larger files
- Auto JSON formatting to test for equivalence (pretty print + object key sort)
- Drag-and-drop text files directly into the input fields
- Dark mode

Description: Deploying an AI agent often means dealing with backend setup, managing vector databases, and other tedious tasks. To simplify the process, we took a low-code approach using tools like Flowise and Qdrant.
Flowise made it easy to build the logic without heavy coding, while Qdrant handled vector storage seamlessly. Pre-configured environments and automation helped from Qubinets cut down on redundant steps. Here’s a breakdown of how we streamlined the entire deployment process and got our AI agent running quickly.

38. Show HN: Daily puzzle game where you build a bridge of your own words (SolidJS)
URL: https://bridj.link/
Author: jaaamesey
Description: Hey HN,
My partner and I made a daily puzzle game called “bridj.link” (the dot is not silent). Thought I’d give Hello World in SolidJS a shot but ended up taking things a bit too far (to the point where we’re now on our 99th puzzle!)
Each puzzle has thousands of valid solutions. The tutorial goes into a bit more detail, but basically, each puzzle consists of a top word and a bottom word. These words need to be linked together using real words, made up of the tiles provided.
In addition to an emoji summary of your solution, you’ll get a fancy link that you can share with others upon completing a puzzle. That link will reveal your full solution to whoever clicks it, but only once they’ve completed the puzzle themselves.
There’s an explainer on the scoring system tucked away behind the “Menu” button if you’re curious, but it’s probably something you don’t need to care about until after you’ve got the core mechanics down. If you want to keep playing past today’s puzzle for whatever reason, there’s a practice mode for that.
Keen to hear your thoughts!

39. Show HN: A website for comparing protein powder prices
URL: https://nutritionprices.com/
Author: parmigiano
Description: diskprices.com, but for Protein Powder!
Buying protein powder is a mess, and comparing different products is frustrating, since all brands choose their own serving sizes. By collecting nutrition facts, and normalizing the serving to contain 25 grams of protein, we can properly compare price/nutrients per serving.
Inspired by diskprices.com, the idea is to provide an equally functional interface to compare products. The prices are collected once a day, currently from iHerb US. Aiming to improve the coverage soon.
Any tips / suggestions / other feedback more than welcome :)

43. Show HN: Indian NY Times Connection
URL: https://www.shabdify.com/
Author: yajatgulati
Description: I love playing NYT Games with my friends, the Mini crossword, Strands, Connections and of course Wordle. But here’s the thing – I often find myself getting stumped by American references, and it got me thinking: why don’t we have something like this in India?
I’m a college student, who’s built a few apps and websites over the years so I said fuck it, I’ll built it myself.
It’s called Shabdify, it’s inspired by NY Times Connections. It’s super simple, there are 16 words, 4 groups of 4. The words are jumbled and you need to guess what the 4 groups are. The groups can be anything from movies, linguistic references etc.
The reason I love these games is that, surprisingly they fill the same void that scrolling on social media does. You’re on the toilet, waiting for a bus, eating breakfast, and you just want your brain to be engaged. Well, this is just so much better, it reduced my own screen time by quite a bit so I thought it was a shame that the world (besides America) was missing out.
This is a complete passion project, no ads no nothing. I would love any feedback.

Description: Scaffoldly allows you to run any HTTP server inside AWS Lambda. It requires no code changes to your existing server and a simple configuration in the project’s Cargo.toml. Deployments can be done locally or in GitHub Actions.
In this example, we’re running a axum server in AWS Lambda, and the scaffoldly toolchain handles packaging, deployment, and routing of AWS Lambda HTTP requests.

URL: https://github.com/archiewood/gosql
Author: archiewood
Description: I’ve always been curious about how SQL engines actually work.
So I built a minimum viable SQL engine in Go.
- Supports CSV files as tables
- Supports SELECT, FROM, WHERE, LIMIT
It’s very simple:
1. Parses query string
2. Converts it into an AST representation
3. Executes the query against the CSV
4. Returns the results

47. Show HN: ServerlessAI – Build, scale, and monetize AI apps without back end
URL: https://serverlessai.dev/
Author: HeavenFox
Description: Hello HN,
I’ve always loved building frontend-only apps—those you can prototype over a weekend, host for free on GitHub Pages, and scale to millions of users. Unfortunately, AI-enabled apps complicate things, as exposing your OpenAI key to the world is obviously a no-go. This also means mobile developers often have to run their own servers.
That’s why I built ServerlessAI, an API gateway that lets you securely call multiple AI providers directly from client side using OpenAI-compatible APIs. You can authenticate users through any identity provider, like Google or Apple, and set per-user request or spending quotas. You can also define an allowlist for endpoints and models. To monetize, you can apply different quotas for various user tiers.
To start, I recommend checking out our tutorials, where we walk you through building a complete, deployment-ready AI app in 5 minutes. We’ve got tutorials for React, Next.js, and iOS: https://serverlessai.dev/docs/tutorials/
Our long term vision is to offer the best toolkit for AI developers at every stage of their project’s lifecycle. If OpenAI / Anthropic / etc are AWS, we want to be the Supabase / Upstash / etc. We are building optional out-of-box tools for authentication and payment management, so you can roll out your prototype faster. In the future, we want to provide the best prompt engineering tools for fine-tuning, A/B testing, and backtesting, as well as the best observability tools.
We’d love to hear your feedback. Thanks for stopping by!

49. Show HN: TrustGraph – Do More with AI with Less (Open Source AI Infrastructure)
URL: https://github.com/trustgraph-ai/trustgraph
Author: cybermaggedon
Description: Hi HN,
We’re Daniel and Mark, the creators of TrustGraph (https://github.com/trustgraph-ai/trustgraph). TrustGraph is an open source, full end-to-end AI infrastructure that automates knowledge graph building and querying along with modular agent integration. A unique aspect of TrustGraph is that the graph building is a one-time process that builds reusable knowledge cores that can be stored, shared, and reloaded. You can read more about TrustGraph knowledge cores here (https://trustgraph.ai/docs/cores/).
Throughout our careers, we’ve been faced with huge datasets of unstructured knowledge - thousands of pages, tens of thousands of pages of documents with facts disconnected by thousands of pages. Knowledge graphs and AI unlock a solution to convert this unstructured knowledge to an enriched knowledge structure enabling AI to extract accurate intelligence.
Unlike AI frameworks, TrustGraph is your infrastructure. All the services, stores, observability, and backbone gets deployed in a single package. Once deployed, TrustGraph enables you to:
- Ingest PDF, TXT, and MD files in batches
- Chunk ingested docs with multiple chunking options and parameters
- Structure the knowledge in each chunk as RDF
- Convert each chunk to mapped vector embeddings
- Store RDF triples in either Cassandra or Neo4j
- Store vector embeddings in Qdrant
- Monitor system performance, like CPU/memory resources and token throughput, with a Grafana dashboard
- Store and load knowledge cores
- Query the graph store and VectorDB for AI generation
- Easy agent integration with Apache Pulsar backbone
TrustGraph is model agnostic and currently supports:
- Anthropic API
- AWS Bedrock API
- AzureAI API
- OpenAI API in Azure
- Cohere API
- Llamafile API
- Ollama API
- OpenAI API
- VertexAI API
TrustGraph is deployed with either Docker or Kubernetes. For knowledge extraction, we’ve seen Claude 3 Haiku and Gemini 1.5 Flash provide the best value. However, with a quality knowledge core extraction, you can use locally deployed SLMs to get big LLM performance on your dataset. Our goal is to be able to use TLMs (models 3B parameters and smaller) for AI generation on knowledge cores.
Trust is the foundation of TrustGraph’s goals. TrustGraph aims to enable “accuracy first” AI generation with our fully transparent and open source approach. Realtime observability will enable doing more with AI with less - less compute, less memory, and less power. We have a vision for “open knowledge cores”, that will contain common terms, definitions, and information to aid the generation for niche use cases driven by community.
We hope you join us on this journey of doing more with less. Daniel and Mark

Author: yunusefendi52
Description: It’s a habit tracker app with fairly simple features where user log everyday habit, built with Flutter. Syncing to Google Drive incrementally using timestamp last synced data with offline-first mode. It uses Google Drive application-spesific data so the app can only access this app directory only and can’t access your other data.
Currently Android only, I don’t have iOS dev subscription.

Description: When COVID-19 started I needed something to get busy to not go crazy. I happened to work on our app WCAG compliance for a few months at the time and was frustrated by the state of of accessibility-related tools for developers.
I’ve spend two months delivering a tool that is easy to understand and helps catching accessibility issues on my apps. A few years later it’s pretty popular despite being mostly abandoned.
I will be happy to work on this further but honestly lost my enthusiasm some time ago. I’d love to get in touch with some company in the accessibility testing space and discuss how to improve it.

URL: https://gist.github.com/rmtbb/e42d870a59a7f98091e734674831072b
Author: somefries
Description: Hey HN,
I recently found myself needing a quick way to preview HTML and SVG code without having to copy it into an IDE, save it, and then open it in a browser. ChatGPT’s new canvas feature is great for generating code, but it doesn’t provide a way to preview HTML directly.
To solve this, I made a small bookmarklet that allows you to instantly preview HTML from your clipboard in a new tab. Just copy your HTML, click the bookmarklet, and it will render immediately.
It’s a simple tool, but it’s saved me a lot of repetitive steps, and I figured it might help others too.
The bookmarklet code and instructions for saving it are included in the post.
Happy to hear any thoughts or suggestions!
Thanks, and I hope it saves you some time.
