3. Show HN: GitHub-assistant – Natural language questions from your GitHub data
URL: https://github.com/reltadev/github-assistant
Author: aazo11
Description: Simon(sfarshid) and I spend a lot of time on GitHub. As data nerds we put together a quick tool to explore your repository’s data.
How it works:
- Data Loading: We use dlt to pull data (issues, PRs, commits, stars) from GitHub
- Semantic Layer: Relta wraps the underlying dataset into a semantic layer so the LLM doesn’t hallucinate.
- Text-to-SQL: A text-to-SQL agent transforms your plain-English question into a query using the semantic layer
- Generative Charts: assistant-ui dynamically generates a chart based on the SQL query
- Refinements: If the semantic layer can’t handle your question, our agent submits semantic layer improvements via pull requests
Hosted version: https://github-assistant.com
Demo Video: https://youtu.be/ATaf98nID5c
Check out the repo + hosted version and let us know what you think.

Author: harry247
Description: Hey Hackers,
I was building multiple projects lately, and integrating logging was way too much for me. Managing self hosted ELK stack, or using existing log monitoring services (running their agent was consuming hell of resources on my tiny servers). It took me a day to code my own logging server, and client for python projects (serving as python packages - pypi), named it HueLogs.
Sharing with you all, please feel free to contribute if you like. I might be adding a npm package for javascript client if I get chance to code tomorrow.
Few features too add:
- 30 min, last day logs etc.
- Beautify UI
- Add steps in README to run it without docker
I am currently using Flask, up for the suggestions to make this lighter. Didn't profile it yet, assuming flask is light.
Cheers! Harman

15. Show HN: Shortcards – Mac keyboard shortcut cheatsheets for friends and family
Author: namu-313
Description: Many people (including my close family) are not aware of the various useful screenshots macOS and its apps provide. Often they are very surprised when I show them handy shortcuts like the one for deleting an entire line, or the one that starts a screen recording.
You can, of course, look up keyboard shortcuts in the menus and there are lots of shortcut cheat sheets on the internet. But I found none of them really appealing to nontechnical people.
So, last year, I designed my own shortcut cheat sheet. But instead of putting it all on a full-size letter sheet, I had the idea to print mini cheat sheets for various apps and topics in the size of business cards. That way, you can easily have one or two cards on your desk for the shortcuts you really need. I had these printed on cardboard paper and started giving them away to friends and family.
I think knowing your shortcuts really makes your life easier. Everybody should have their set of cheat sheet cards on their desk! But, of course, I can’t send a deck of cards to everybody.
As an app developer, I thought: What better way is there for us than creating an app with the shortcut cards?
The result is “Shortcards”, which is both a website and an app. You can simply look up and learn shortcuts on https://shortcards.app
And with the free native app, you get a handy reference directly on your Mac or iPhone. In the app, you can quickly search for shortcuts, conveniently filter by topic, and mark your most-used or high-priority cards as favorites for instant access. It includes shortcuts for basic macOS system commands, Finder navigation, and text editing.

18. Show HN: Turning GitHub Engagement into Leads for Dev Tool Companies
URL: https://revmax.pro/
Author: dhaval_n
Description: Hi HN,
As a Marketing Lead at a dev tool company for over 2 years, I often struggled to generate quality leads. Traditional tools like 6sense, Demandbase, ZoomInfo, and RB2B didn’t quite work for us. They relied heavily on static databases or generic intent signals that didn’t resonate with our audience—developers.
After trying pretty much everything, I stumbled upon a new approach: leveraging GitHub activity as a source of intent signals. By identifying developers who starred, forked, raised issues, or discussions on relevant open-source repositories, I could pinpoint high-intent leads with a level of precision traditional tools just couldn’t match.
That experiment turned out to be a game-changer. Now, I’ve built a platform to make this process seamless and accessible to others. The tool automates the sourcing of developer engagement signals from GitHub (open-source repos only) and delivers actionable insights, like LinkedIn profiles, directly to Slack, email, or a dashboard.
Key Highlights: -- It’s live: There’s a free plan available for anyone to try.
-- Developer-first: Helps dev tool companies focus on developers actively engaging with their repos or competitors’ code, rather than chasing generic leads.
-- Ethical use: Data is sourced from public, open-source repositories via GitHub’s API. We’re continuously reviewing guidelines to ensure compliance.
-- How do you view the ethics of using public developer activity for lead generation?
-- What other platforms or signals would you like to see integrated?
We’re just getting started and would love your thoughts. Check it out here: https://revmax.pro. You can reach out to me directly at dhaval@revmax.pro

20. Show HN: TapLock – double tap to lock your Android device
URL: https://github.com/modelorona/TapLock
Author: modelorona
Description: When I switched from a Samsung to a Pixel, I was shocked to discover that the 'double-tap to lock' feature (where you double-tap an empty area of the home screen to lock your device) wasn't a native option.
This feature existed as far back as 2014 on my LG G3, so why is it missing on the Pixel?
While there are alternatives on the Play Store, most are either closed-source or bundled into custom launchers — neither of which I wanted. Sending the lock-screen signal requires the Accessibility Service, and I wasn’t comfortable granting that level of access to a closed-source third-party app.
So, I decided to create my own solution. My app is completely open-source, contains no tracking or analytics libraries, and doesn’t make any external requests. The Accessibility Service permission is used solely to send the lock-screen command. I tried to find an alternative to locking the screen without requiring Accessibility permissions but the options either required root or weren't what I needed.
I also saw this as a chance to explore modern Android development. The last time I built an app from scratch, Jetpack Compose didn’t even exist. While I didn’t hate the experience, I won’t say I miss the days of wrestling with XML either. That said, some aspects of Compose felt harder to fully grasp and work with.
You can download it here: https://play.google.com/store/apps/details?id=com.ah.taplock
Source code is here: https://github.com/modelorona/TapLock
Any suggestions or feedback, please feel free to leave here or on the repo.

21. Show HN: A low code AI/ML API deployment Platform
URL: #
Author: farhan0167
Description: Hi all, so I've been working on this low to no code platform that allows you to spin up deep learning workloads(I'm talking LLM's, Huggingface models, etc), interconnect a bunch of them, and deploy them as API's.
The idea essentially came up early in September, when experimenting with combining a Huggingface based BERT model with an LLM at work, and I realized it would be cool if I could do that instantly(especially since it was a prototype). At the time, I was considering a platform that could essentially help you train deep learning models without any code. It was my observation that much of the code required to train or even run inference on HF models have matured significantly. But before I solved that problem, I wanted to solve inference. Initially inspired by n8n and AWS Cloudformation, I built out otto-m8 (translates to automate). Given a json payload that lists out all the resources, and how each model is interconnected, launch it as one-off API the user can query. And thanks to Reactflow, the UI was just something I couldn't just not implement. And as I built it out, I did not want to miss out on the LLM and Agent bit.
With otto-m8, today, you can launch complex workflows by interconnecting HF models and LLM's(currently it supports OpenAI and Ollama only). But I like to see it being more than that. At the core, every workflow is an input process output model. Inputs get processed and there's an output. Therefore, with the way things are setup, one can integrate almost anything and make it interconnectable.
Project Link: https://github.com/farhan0167/otto-m8
Let me know what you guys think. I really would love feedback, and if you think this project is cool, please support me through a Github star!

31. Show HN: I started coding 2 weeks ago and my app hit 8.5K visitors in a day
URL: #
Author: gloseeker
Description: Hey everyone!
I recently started my coding journey and wanted to share a quick milestone. Two weeks ago, I knew absolutely nothing about coding. Today, my app [AmazonFinder.deals](https://amazonfinder.deals) has helped users find hidden discounts on Amazon—and it just hit 8.5K visitors in a single day!
Why I built it: I noticed how time-consuming it can be to hunt for great deals on Amazon. My app simplifies the process by letting users filter discounts by category, percentage, and more.
How I did it: I used the following tools to build it:
- Next.js for the frontend
- MongoDB for the database
- Tailwind CSS for styling
Key stats:
- 8.5K visitors in a single day
- 338 visitors from one tool, 8.1K from another tool tied to my platform (MySupermarketCompare.co.uk)
What I learned:
- Start small and build fast—don’t overthink your first project.
- Share early and often; Twitter and Product Hunt helped me gain traction.
- It’s not about perfection—it’s about solving real problems.
I’m still new to all of this, but I’d love your feedback on the app. Are there features you’d find useful? Anything you’d improve?
Looking forward to hearing your thoughts!

32. Show HN: TurboGist – Real time code sharing without leaving your editor
Author: moeen-mahmud
Description: Please try and read this if you're a developer, if you're not you can still try that out!!
As a developer, I work within a team to build software. However, when I wanted to share a piece of code with my team members or ask for any suggestions on any business logic, classes, or functions, I needed to copy the code and send it via Microsoft Teams and Slack. I was thinking what if I could share that piece of code using my code editor that doesn't need to switch between screens which is clunky and time-consuming?
That was the actual pain point and motivation to build Turbogist, which lets you share codes in real time with others. Right now I only created the extension for VS Code and am working on building a plugin for JetBrains as well. First thing first, I want to validate the idea.
However, I have some plans to add some additional features that will integrate a seamless snippet and code sharing by integrating GitHub Gists or Pastebin-like services. You can try out the extension and see the tool in action by visiting the landing page and joining the beta.
Looking for your input on:
- How this would fit your workflow?
- Must-have features or integrations (e.g., GitHub Gist, PasteBin, etc.)?
- Pain points in your current code-sharing process?
Thank you for checking this out, looking forward to your feedback!

Description: Hey HN! I built a fun little website that generates "Pseudo-Chinese (偽中国語)" using an LLM. It takes your input and transforms it into a sentence composed only of Kanji or Chinese characters, but structured with Japanese grammar. This makes it surprisingly readable to both Japanese and Chinese speakers who can leverage their knowledge of shared characters.
The inspiration for this project came from another popular Japanese app called "対多." Its developer mentioned struggling to achieve satisfactory "Pseudo-Chinese" generation using ChatGPT. This piqued my curiosity, and I decided to tackle the challenge myself.

35. Show HN: Fill, sign, edit PDFs and much more
Author: talha345
Description: Hi HN, I built a new and modern PDF Editor. I had been using some online PDF Editors since years and over the period of time I found that most of them were either slow and outdated or bloated with un-necessary features. Another pain point was all of the PDF editors mentioned "Free" but right after you do edits and want to export anything, they ask you to pay. I decided to fix my own itch and built PDF Editify.
Using PDF Editify, users can fill, sign, edit, redact, annotate PDFs and much more. The free version allows users to export 3 PDFs with unlimited edits per week. We are constantly working on new features, some of which are:
- Digital Signatures (currently we only support Electronic Signatures)
- PDF Templates Catalog
- OCR PDFs
This is my first product and we have good feedback from our users. I would love any questions, comments or feedback from the HN community and any ideas for marketing would be appreciated since I (being a tech guy) really find marketing boring.

36. Show HN: Supergateway – Run MCP stdio servers over SSE
URL: https://github.com/supercorp-ai/supergateway
Author: Nedomas
Description: Hi guys,
I’ve just released Supergateway and it allows to use MCP servers with stdio on remote assistants over SSE.
Now most of MCP servers only support stdio transport and this is problematic if you want remote assistants to access them. MCP spec has SSE transport which works with remote HTTP connections but it is rarely used by MCP server authors. So I’ve created this gateway that allows you to run stdio transport MCP servers and tunnel them via SSE transport.
It’s very simple to use. Run any stdio MCP server like this:
npx -y supergateway --stdio "uvx mcp-server-git"
It’s totally open-source and supports pretty much any MCP server.
Built this since we have an AI infrastructure platform (https://superinterface.ai) that allows you to use MCP servers in remote assistants and we saw that we cannot really run any community MCP servers without something like this.
It’s def pretty cool to see remote assistants embedded on a website being able to access these cool MCP servers.
Let me know what you think! /Domas

Description: Hey HN! I’ve been working on PennyMeal, an AI-driven meal planner that tackles two big hassles: sticking to specific nutrition goals (like hitting exact macros) and staying within a grocery budget—using real-time prices from nearby stores.
Why I Built It I’m someone who geeks out over nutrition and saving money, but every time I tried to manually plan meals, I’d miss out on store discounts or forget to track certain macros. So I created PennyMeal to automate all that, and it’s grown into a pretty comprehensive tool.
Key Features AI-Powered Meal Planning: Enter your daily protein, carb, and fat targets, and it suggests meals that fit those macros. Real-Time Grocery Prices: Pulls pricing data from local stores (coverage can vary, still improving!) so you can see exactly how much each ingredient will cost. Weekly Ads & Discounts: Tries to incorporate current deals and promotions when building your grocery list to keep you under budget. Exact Grocery Items: Tells you precisely which products to buy based on your meal plan and where they’re cheapest. Pantry Management: Keeps track of what you already have to avoid waste and double-buys. How It Works AI Engine: Looks at your macro constraints, budget, location-based prices, and weekly ads. Recipe Matching: Each meal has a detailed nutritional breakdown—perfect for anyone who wants to keep tabs on everything from protein to fiber. Stack: React/TypeScript on the front end, Node/Express on the back end, plus data from various store APIs and a discount aggregator. You can browse and generate plans without an account (to make it easy to try). If you want to save plans or tweak them, a simple login is required.
Feedback Welcome! I’d love to know:
Do you find the AI suggestions helpful for hitting specific macros? Are the real-time prices/discounts accurate or missing anything in your area? What else would you want from an AI meal planner? I’m here to answer questions, so fire away. Thanks for checking out PennyMeal, and I hope it makes your meal planning less stressful—and a bit more wallet-friendly!
