Kreuzberg – Modern async Python library for document text extraction
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…
In plain words
Kreuzberg is a Python library for extracting text from PDFs, images, and office files using modern async programming patterns. Built with async/await syntax and type hints, it operates without external API dependencies and handles both I/O-bound and CPU-bound tasks through optimized worker pools. The library targets Python developers building async applications who need efficient document processing integrated into their workflows.

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. Here is the repo: https://github.com/Goldziher/kreuzberg Staring is caring

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
