1. Show HN: Kreuzberg – Modern async Python library for document text extraction
URL: https://github.com/Goldziher/kreuzberg
Author: nhirschfeld
Description: I'm excited to showcase Kreuzberg!
Kreuzberg is a modern Python library built from the ground up with async/await, type hints, and optimized I/O handling.
It provides a unified interface for extracting text from documents (PDFs, images, office files) without external API dependencies.
Key technical features:
- Built with modern Python best practices (async/await, type hints, functional-first)
- Optimized async I/O with anyio for multi-loop compatibility
- Smart worker process pool for CPU-bound tasks (OCR, doc conversion)
- Efficient batch processing with concurrent extractions
- Clean error handling with context-rich exceptions
I built this after struggling with existing solutions that were either synchronous-only, required complex deployments, or had poor async support. The goal was to create something that works well in modern async Python applications, can be easily dockerized or used in serverless contexts, and relies only on permissive OSS.
Key advantages over alternatives:
- True async support with optimized I/O
- Minimal dependencies (much smaller than alternatives)
- Perfect for serverless and async web apps
- Local processing without API calls
- Built for modern Python codebases with rigorous typing and testing
I Would love feedback!
The library is MIT licensed and open to contributions.

2. Show HN: I Built a Reddit-style Bluesky client – still rough, but open to ideas
Author: lakshikag
Description: I’ve been messing around with Bluesky for a while, and one thing I really missed was a proper way to browse discussions in a structured, Reddit-like way specially myself being daily reddit user. So, I ended up building a Reddit-like client for Bluesky that scratches that itch: Threadsky.app
It pulls in trending topics, lets you explore conversations with a threaded view (so no more getting lost in replies), and even allows users to create channels with customizations, basically, like subreddits but on Bluesky.
That said, this is still pretty barebones, and there’s a lot to improve. I really need feedback from actual users to shape where this goes next. Some planned features include markdown support, longer posts, and better mod tools for communities.
For privacy-conscious folks: Only details about channel customizations are stored on our servers. Everything else remains securely stored on your own PDS (Personal Data Server), just like the rest of Bluesky.
Also, I’m planning to open-source the project once I’ve polished things up a bit more.
Would love to hear your thoughts on what’s missing and what would make this actually useful?

8. Show HN: XOC 1.6.0: A Powerful, Commercially-Proven Compiler Framework
URL: #
Author: steven_known
Description: Hello everyone, I am thrilled to announce the release of the XOC Compiler Framework 1.6.0, a retargetable compiler infrastructure licensed under the BSD license. This release marks a significant milestone in the evolution of XOC, which has been powering commercial compilers and achieving remarkable performance and stability in production environments. About XOC Compiler Framework The XOC Compiler Framework is an industry-grade compiler infrastructure designed to support the compilation and analysis of both static languages (such as C, C++, Java) and dynamic languages (such as JavaScript). It is the result of independent research and development efforts and has been battle-tested in real-world applications, including Alibaba's YunOS/AliOS mobile operating system and Cambricon's proprietary compiler for AI chips. XOC is based on the open-source compiler framework initially released by Alibaba in 2015. Since then, it has been continuously developed and enhanced to provide a robust and flexible foundation for compiler development
Key Features and Advantages Multi-Level Intermediate Representations (IR): XOC provides a hierarchical IR system that enables efficient code transformation. It supports the composition of arbitrary simple IRs into complex IR trees to accurately represent the syntax of various languages. Retargetable Code Generation: XOC includes XGEN, a retargetable machine code generator capable of producing code for multiple architectures, including ARM and x86. XGEN provides features such as IR2OR translation, instruction scheduling, register allocation, instruction packaging, and assembly code generation. Comprehensive Optimization and Analysis Tools: XOC offers a rich set of optimization and analysis tools, including aggressive flow-sensitive alias analysis, field-sensitive alias analysis, Register and Memory SSA (Static Single Assignment) forms, interprocedural analysis, inlining, dead code elimination, copy propagation, GCSE, GVN, and sophisticated control flow and peephole optimizations. Stand-Alone Algorithm Library: XOC does not rely on any standard library, providing all basic algorithm libraries such as Vector, List, Map, Dense Bitset, Sparse Bitset, Graph, Mempool, Big-Integer, Linear Algebraic library, File Operations, and Linear Programming Solver. Modular Design: XOC is designed to be easily integrated into other projects as an independent module, making it highly adaptable for various use cases. C Frontend (XOCFE): XOCFE is a concise and clear C compiler frontend that outputs an Abstract Syntax Tree (AST). It supports pure C99 and is easy to understand and modify. Polyhedral Transformation (XPOLY): XOC includes XPOLY, a tool for polyhedral transformation, linear programming solving, and polyhedral-based dependence analysis, enabling advanced loop optimization.
Commercial Applications and Stability The XOC Compiler Framework has been deployed in numerous commercial applications, demonstrating its reliability and performance. It has been used to optimize Android applications on YunOS, achieving significant performance improvements. Additionally, XOC has been utilized in the development of dexpro, a Java program analysis tool for detecting potential bugs and performance issues, as well as in static analysis tools for enhancing the execution speed of JavaScript engines like V8.

Author: rtills
Description: In my work in EdTech, I see AI enhancing efficiency — speeding up grading or generating lesson plans. While useful, these applications don't fundamentally change how we learn.
To explore new possibilities, I've hacked together debdeb.io.
It allows users to create debates on any topic and immediately access both sides in text and audio formats. You can vote on debates and, if you sign-in, see what you've created.
I wanted to try introducing different modes (text and audio) into learning whilst having a fun way to learn critical thinking.

A summarized by ai presentation, grouped by theme, of articles from national media outlets (5 or 6 for now) with the goal of providing a quick daily review. Each article is accompanied by a series of recommendations through embeddings, which allows related articles from competing media or from the past to resurface. It's very personal at the moment, but I realize that this has become my only source of news. I was wondering what you think about this approach and existing alternatives.

16. Show HN: CSSGrid – 2.7k LOC CSS-Grid layout engine targetting embedded (Nim)
URL: https://github.com/elcritch/cssgrid
Author: elcritch
Description: Hey I've been working on this project for a few years. It's a smallish (~ 2.7k loc w/ tests) implementation of CSS grid.
My ultimate goal with this is to be able to make full featured UIs on embedded devices like the ESP32.
I just did a fairly big update which adds a bunch of features that make it into a reasonably complete CSS Grid implementation:
- basic html/css style layout for nodes not in a grid
- basic html layout using constraints like percent parent (20'pp), auto (cx"auto"), content-min (cx"content-min")
- support for constraint operators including min, max, - and + (limited to single level, e.g. no
min(min(x,y),z)) - basic and grid layouts now support min-size and max-size constraints (e.g. like CSS min-width)
It's a weekend project. It's been pretty fun figuring out how CSS Grid works and how browsers implement parts of their layout routines. Especially how auto and frac works in CSS Grid. The core implementation turns out simple but subtle.
This project is similar to Taffy in Rust, however, the implementation is a bit simpler and much less thorough. It doesn't support CSS flexbox either.
Feedback or suggestions would be awesome!

17. Show HN: My customer uses Anydesk for remote IoT devices. So I got an idea
URL: https://noloops-demo.vercel.app/remote-execution
Author: melb_jeds
Description: My customer is owning IoT devices for like, 10k of them.
And when there's a problem with production devices. They're currently need to use Remote desktop tool to manually fix the problem. And sometime it can happen with almost 1k devices at the same time. So their whole operation team will be on fire that week.
I got an idea of building tool to automate these works. But it's gotta be flexible enough to fit all of their cases. And easy enough for op team to use.
So I decided to make a software that do literally nothing more than running pure shell script for them.
The idea is that I try to make it have no abstraction layer at all. And focus more on running script efficiently.
---
I actually build demo prepared for presenting them. Any review will help me a lot honestly.

19. Show HN: JobBridge – Real-Time AI Interview Assistant
Author: marcosjdev
Description: I built Job Bridge, an AI tool that provides real-time assistance during job interviews. It listens to interview questions and suggests relevant responses on the fly, adapting to the candidate’s resume and the job description. The idea came from my own experience struggling with high-pressure interviews and thinking about how AI could provide subtle, non-intrusive support.
How it works: Runs in the background during video calls (Zoom, Teams, Meet, etc.). Uses real-time speech processing to generate response suggestions. Adapts to different industries and job roles based on context. Supports multiple languages.
Would love to hear your thoughts—especially around ethical concerns, undetectability, and any ideas for improvement. Feedback is much appreciated!

After some serious server headaches, the world’s first 24/7 AI podcast stream is live! It generates 5-10 minute segments with different AI hosts and even responds to viewer comments (eventually) by turning them into podcast episodes.
The idea is to create a space like Lofi Girl where people can hang out or actively chat. I see this as the start of new community experiences around AI—more of a “movie theater” vibe compared to Character AI’s “Netflix” feel.

Description: I built this tool to transfer files using just the URL, without storing files on a server.
The file is Base64-encoded and embedded as a payload within the URL via the URI fragment (delineated by the # character) which means the file/payload shouldn't get sent to the server.
Built mainly for fun, but I have found limited use cases for it (eg. I use a shared mouse/keyboard + clipboard across multiple machines, so use this to transfer files between them; I also have found it useful for file transfers to mobiles - via Edge's URL to QR code feature).
It's really only suitable for small file transfers as you might imagine!

38. Show HN: AI Powered Grocery List Suggestor
Author: edemirci
Description: Hey HN,
I just build this app and published it. It's my first swift app that I published on app store. I am open to feedback and suggestions. You do not need to sign up or pay anything to try, although you would need to download it.
Here is what it does:
- Given your dietary restrictions that you choose from the profile page it suggests you grocery lists.
-If you want to cook a dish maybe something spesific and you are doing grocery shopping but do not know what to buy then this app helps you if you type in the food name you want to cook and it generates a grocery list.
-The last feature is that it can suggest random meals to you from like 800 cuisines. For this part, I opened wikipedia and searched for all the different cuisines in the world after literally copy pasting 800 cuisine names in a list and by randomly selecting one of the cuisines, the app then makes an api request to openai to come up with a dish within that cuisine and to create a grocery list for that spesific dish.
It was a side project for me but I wanted to see how far can I push this but I stopped after a while and I did not add any more features. Would love to hear your thoughts and any feedback you have :)
Cheers!

URL: https://rlafuente.com/post?post=2025-2-14-launching-describe
Author: andes314
Description: I've been working on Describe, a simple CLI tool that scans a directory and generates a structured Markdown file (codebase.md). The idea is to make it easier to feed relevant codebase information into AI tools while filtering out noise.
It respects a .describeignore file (same format as .gitignore) to exclude files and directories, which helps keep the output focused. This is particularly useful when integrating with AI-assisted workflows or just getting a high-level overview of a project.

Installable with homebrew!!

41. Show HN: Hackyournews.com v2
URL: #
Author: ukuina
Description: A year and a half after I published https://HackYourNews.com, I've rewritten it to be neater and added support for more news sources.
HackYourNews.com v1 had a great response on HN [1] and consistently sees ~2k weekly unique visitors.
There were many long-standing requests that I wanted to fulfill (thanks for your patience!): a proper dark mode, correct rendering on mobile devices, and more cogent summaries.
This rewrite is the result. gpt-4o-mini reduces the cost of summarization to an absurd degree, so it's now sustainable to keep this free service going!
Someday, I hope to use the Batch API [2] to drive down costs even further.
Enjoy.
