AMA – I’ve built 7 commercial RAG projects. Got tired of copy-pasting boilerplate, so we open-sourced our internal stack.

Hey folks,

I’m a senior tech lead with 8+ years of experience, and for the last \~3 I’ve been knee-deep in building LLM-powered systems — RAG pipelines, agentic apps, text2SQL engines. We’ve shipped real products in manufacturing, sports analytics, NGOs, legal… you name it.

After doing this again and again, I got tired of the same story: building ingestion from scratch, duct-taping vector DBs, dealing with prompt spaghetti, and debugging hallucinations without proper logs.

So we built ragbits — a toolbox of reliable, type-safe, modular building blocks for GenAI apps. What started as an internal accelerator is now fully open-sourced (v1.0.0) and ready to use.

Why we built it:

I’m happy to answer questions about RAG, our approach, gotchas from real deployments, or the internals of ragbits. No fluff — just real lessons from shipping LLM systems in production.

We’re looking for feedback, contributors, and people who want to build better GenAI apps. If that sounds like you, take ragbits for a spin.
