3. Show HN: An MMO virtual office for remote devs
URL: https://joinhive.devmode.digital
Author: bcowde
Description: For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features:
- AI-powered presence to represent you when you’re offline.
- Live video streaming to showcase your work in real time.
- VS Code integration to broadcast your status live.
- GraphQL API for full customization and hackability (such as using your own agents)
- Web3 donations to support and get support from other builders.
In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with a few simple items. There are a limited number of desks available for now.
Hive is meant to keep your projects visible, make it easier to connect with others, and help you stay motivated by seeing what others are building. Feedback is welcome!

4. Show HN: Toivo – A Smarter Assistant
URL: https://toivo.ai
Author: planar_vector
Description: We've all been there: drowning in to-do lists, wasting hours on repetitive tasks like booking appointments. Existing AI assistants promise help, but often fall short when it comes to actually completing tasks.
At Toivo [1], we're building a smarter solution. We use Microsoft’s awesome AutoGen [2] framework for agentic applications along with a custom layer of multi-agent orchestration, built specifically to handle ambiguity and allow you to get your task done. This allows Toivo to navigate complex scenarios, ensuring your tasks get done, not just started.
Here's what sets Toivo apart:
- Completes tasks, not just starts them: Tired of AI assistants that leave you halfway through a booking? Toivo uses multi-agent orchestration to handle unexpected situations and complete the task from start to finish.
- Learns and adapts over time: The more you use Toivo, the better it understands your needs and preferences. Imagine an assistant that remembers your preferred restaurant, appointment types, and even travel details.
- Focuses on automation, not information overload: Toivo doesn't just give you endless search results. It uses its intelligence to filter, compare, and complete tasks efficiently.
We're excited to revolutionize the way you get things done! Toivo.ai [1] is still under development, but we'd love to hear from you - feedback, suggestions, everything in between.

5. Show HN: A shadcn/UI theme generator (with chart and sidebar)
URL: https://www.readyjs.dev/tools/shadcn-ui-theme-generator
Author: manuelcoffin
Description: Hey HN,
I’m a indie developer, and I build all my projects using Next.js and shadcn/ui.
While there are some shadcn/ui theme generator out there that work pretty well, I couldn’t find one that also generated charts and sidebar colors.
So, I made my own. It’s pretty straightforward, you just pick a primary color and the tool generates a theme for you, including the sidebar color.
Then, you can select a chart primary color and the tool will automatically generate a palette of 5 colors based on it, using color schemes (like analogous, triadic, etc.)
The idea of the tool is to get a color palette quick.
Would love your feedback on this thanks, Manu

9. Show HN: Interactive CV – AI-powered job application assistant
URL: https://www.interactive-cv.com/en
Author: AIHiredMe
Description: Hi HN,
During my paternity leave, I wanted to improve my Frontend skills (I'm mainly a Backend developer). What started as a React learning project evolved into Interactive CV.
The app requires login since it handles personal data, but you can use any sample CV to test it out. There's a demo video on the landing page showing all features in action. Everything is free while I test and gather feedback on the project.
Key features:
- AI analysis of your CV against job descriptions
- Automated CV optimization for ATS systems
- Interactive CV sharing with chat/voice features for recruiters
- AI-powered interview practice
Built with Next.js, Tailwind, Supabase and Langchain (OpenAI).
This grew from a personal pain point: the tedious process of tailoring resumes for each application. Instead of just building another resume builder, I wanted to create something that makes the job search process more interactive and effective.
I'm currently working on improving job tracking features to help manage applications and follow-ups in one place.
Would love your suggestions and feedback on what features would make this more useful for your job search

10. Show HN: Like-local debugging for AWS Lambdas using Terraform
URL: https://github.com/uatec/teleform
Author: uatec
Description: Hi HN!
I built Teleform to make debugging AWS Lambda functions deployed via Terraform faster and easier. Teleform lets you proxy Lambda invocations to your local machine, enabling real-time debugging, live-reloading, and the ability to attach a debugger while running the code in a real AWS environment. No more slow redeployments or mocking services!
Feedback and suggestions are welcome!

11. Show HN: A Security-First Web Server in C with XSS, SQL Injection Protection
URL: https://github.com/erson/misewe
Author: pulkas
Description: I built a high-performance web server in C that prioritizes security from the ground up. Key features:
- XSS protection and SQL injection prevention built into the core
- Rate limiting with IP tracking and automatic blocking
- Comprehensive security headers (CSP, HSTS, CORS)
- Multi-threaded architecture with connection pooling
- Zero-copy file serving for performance
- 100% test coverage with integration tests
- Pure C99, no external dependencies beyond POSIX
The goal was to create a web server that's secure by default and easy to audit (under 2000 lines of C). All security features are enabled out of the box with sensible defaults.
GitHub: https://github.com/erson/misewe
I am looking for feedback, especially on the security implementation and test coverage. The code is MIT-licensed.

12. Show HN: KitchenAI Open Source LLMops development kit. Notebook to server
URL: https://github.com/epuerta9/kitchenai
Author: epuerta99
Description: Over the last year of building AI enabled SaaS applications I became increasingly frustrated at the developer experience of going from AI RAG cookbooks authored in jupyter notebooks to integrating it into my application. Notebooks are great and all but it's incredibly hard to test which part of it was actually important for my app. This led me down the road of having to understand every piece of code in each notebook, deciphering what was important, somehow build an API server as a POC to then hook it into my app. The feedback loop was excruciatingly long, painful, and most of the time I canned the POC because it wasn't quite what I wanted.
this is when it dawned on me that the roles in the AI developer world are fractured into two. Data Scientists and AI devs want easy notebooks to test methods and techniques but do not care to ship something that can be easily be consumed by applications.
In the other camp lies application devs, they just want simple API's that they can use to test quickly and verify these AI methods enhance their application.
Enter KitchenAI.
A way to bridge the gap between the two by converting AI related Jupyter notebooks into a ready made production API server so that it becomes easy to test various cookbooks, recipes, and techniques. Shortening the development cycle in half while giving users a complete local experience with the ability to share them as docker containers.
Completely vendor agnostic and framework agnostic, the goal is to give developers the most about of freedom to use the libraries they already feel most comfortable using.
It comes with a plugin architecture so I envision our team and the community building all sorts of llmops type plugins like evaluation frameworks, observability, prompt management and more.
A lot of hard work was put to provide something that is totally open source, local, and with battle tested technology like Django so that developers didn't have to rely on 3rd party providers.
We’ve launched this repo under Apache license so any developer can use the tool. We're working hard to provide a managed cloud version with much deeper integrations, metrics, analytics, and workflows for those that want have more complex demands

20. Show HN: Replace CAPTCHAs with WebAuthn passkeys for bot prevention
URL: https://github.com/singlr-ai/nocaptcha
Author: uday_singlr
Description: I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly.
What makes Nocaptcha different:
- Uses WebAuthn standard instead of puzzle-solving
- No need for users to remember passwords or solve puzzles
- Open source
Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case.
Looking for feedback particularly on:
- Integration experience
- User experience compared to traditional CAPTCHAs

23. Show HN: Program a robot to solve a maze on a CPU emulator
URL: https://loreley.one/2024-12-wasm/
Author: lukas_b
Description: A little game I made to show off an old project. The functionality of the CPU is derived entirely from simulated logic gates. All the operations and control flow are based on the underlying properties of the logic gates, and changing their operation leads to corresponding changes in function.
The original game code is all python and it runs in the browser using wasm/pyodide. Not very mobile friendly

25. Show HN: fzf-make – a command runner with a fuzzy finder for make, pnpm and yarn
URL: https://github.com/kyu08/fzf-make
Author: kyu08
Description: I built a command line tool that executes commands using a fuzzy finder with preview window for make, pnpm and yarn.
If you use fzf-make, you don't need to remember the names or contents of the commands because it displays them for you.
fzf-make also remembers your execution history. So you can run the command you ran previously easily.
Now, fzf-make can be installed via Homebrew, cargo, nix or paru. For more details, please see the Installation section in the README.
I would appreciate your feedback.

26. Show HN: VocAdapt – YouTube Speech Modifier for Language Learning
Author: nazar_tekhta
Description: Hey guys, I'm building VocAdapt, a browser extension that helps you learn languages from real content—like Wikipedia articles or YouTube videos—instead of relying on textbooks and flashcards.
How it works:
1. Choose any text or YouTube video
2. VocAdapt adjusts content to your 90% comprehension, letting you naturally grasp the rest from context
3. The app injects words from your vocab list into content - giving you frequent and natural exposure to words you want to master
It's in early alpha, so expect bugs and limited features. Try it out and let me know what you think!

27. Show HN: Cartograph – AI-generated code documentation and architecture diagrams
Author: vivekkalyan
Description: Hey there HN! We're Vivek and Si-Yan from Cartograph (https://cartograph.app). We've built an AI-powered code documentation platform that automatically generates reference documentation and creates a visual interactive map of the codebase that serves as both high level architecture diagram and allows you to zoom in to specific implementations.
How it works: We use static analysis to read a codebase and get its symbols and their dependencies, creating a complete map that includes function calls. We use LLMs (Gemini + Claude) to add metadata to this map, as well as augment it in cases where static analysis doesn't work (e.g. HTTP calls). This map is then used to create an interactive map that you can explore to understand the system of your codebase. This works on both monorepos and multi repo projects. We also make use of this map to generate reference documentation for various functions/classes/structs etc in the codebase.
Some demo repos:
NextJS e-commerce template: https://cartograph.app/share/demo/vercel-commerce-next-js-ec...
FastAPI + React template: https://cartograph.app/share/demo/full-stack-react-fastapi-t...
Rust tokenizers library: https://cartograph.app/share/demo/huggingface-tokenizers-rus...
FastAPI/NextJS RAG chatbot: https://cartograph.app/share/demo/weaviate-verba-rag-chatbot...
If you'd like us to process more public repos, please comment below and we will process it on our end.
We plan to improve things significantly over the coming months, but we want to hear your feedback on our product and/or any use cases you think this could be useful for.

28. Show HN: I built a simple chat widget for websites
URL: https://www.axonspear.com/
Author: ahsabit6
Description: Hi HN,
I’ve spent a lot of time looking for tools that help businesses interact with customers. Most of them promise a lot but end up being complicated or not very useful. It’s annoying when you just want something simple that works.
So I made AxonSpear—a live chat widget that’s easy to use and helps businesses connect with website visitors. Here’s what it does:
Live Chat: Talk to visitors in real-time, directly on your website.
AI-Powered Bot: Responds to customer questions even when you're offline.
Analytics: See how people are interacting with your chat, so you can improve.
Customizable UI: Change the look to match your branding.
Easy Setup: Just copy and paste a few lines of code, and it works on your site.
Live chat can help increase conversions, and with AxonSpear, you also get an AI bot to handle the simple questions for you, saving time. Plans:
Essential: $7/month for live chat and basic features.
Premium: $12/month for extra features like analytics and the AI bot.

29. Show HN: Analyze if an idea is AI Agent or Not
Author: shyjal
Description: I'm tired of seeing every AI product calling itself an 'AI Agent.'
I've created 'Agent or Not,' a tool that analyzes product ideas to reveal their true agentive nature. It cuts through buzzwords to provide real insights about AI capabilities.
It uses GPT4o and Claude and takes an average on the following factors to determine whether it is an agent or not.
Autonomy, Goal Oriented, Persistence, Adaptability.

40. Show HN: PVBenchmark – Forecast and Benchmark PV Systems with Real-World Data
Author: muc-martin
Description: Hi HN,
I want to share PVBenchmark with you, a side project designed to help owners of photovoltaic systems forecast and benchmark their solar energy production.
Small plug-and-play solar systems, like those increasingly popular in Germany and around the world, allow homeowners and renters to install solar panels on balconies, rooftops, or backyards. These systems make renewable energy more accessible and help reduce electricity bills. However, understanding how well a system is performing or whether it’s optimized can be challenging.
PVBenchmark is here to address that challenge by offering:
Forecasting: Enter your location and details for multiple surfaces (orientation, tilt, and capacity) to get tailored solar production forecasts.
Benchmarking: Compare your actual energy production with real-world data from other users’ systems. By crowdsourcing production data, the platform builds a growing dataset that enables meaningful comparisons and insights. Over time, the plan is to expand benchmarks to include specific solar modules, inverters, and batteries, providing unbiased evaluation data beyond product marketing claims.
Though the project started with a focus on Germany, PVBenchmark now supports English and supports global production forecasts. As interest in small-scale solar systems grows in the U.S. and beyond, I hope this platform can become a valuable resource for homeowners, renters, and energy enthusiasts alike.
It’s an early version, and I’d love to hear your feedback. Thanks, and I look forward to your thoughts!

41. Show HN: Cut the crap – remove AI bullshit from websites
URL: https://cut-the-crab.streamlit.app/
Author: muc-martin
Description: I’ve spent a lot of time reading articles that promise a lot but never give me what I’m looking for. They’re full of clickbait titles, scary claims, and pointless filler. It’s frustrating, and it’s a waste of my time.
So I made a tool. You give it a URL, and it tries to cut through all that noise. It gives you a shorter version of the content without all the nonsense. I built this because I’m tired of falling for the same tricks. I just want the facts, not a bunch of filler.
What do you think? I’m also thinking of making a Chrome extension that does something similar—like a reader mode, but one that actually removes the crap that gets in the way of real information. Feedback welcome.
