Top 23 LLM Open-Source Projects

1. firecrawl

   1 25 188,065 9.9 TypeScript

   Supercharge your AI agents with data from the web and beyond. Building the library for superintelligence. 🔥

   

   Project mention: A 200 OK is not an article: the bug that made me write my own web layer in Rust | dev.to | 2026-09-22

   I'm not going to pretend the field is empty. Firecrawl is the hosted API you can call from a lambda. If you live in Python, Crawl4AI is mature and ships a Docker server. Scrapling does adaptive parsing with session and proxy control. For plain browser automation over MCP the reference answer is still Playwright MCP. All four are in the repo's comparison table, and if you want a URL you can hit from a serverless function, use a hosted service.

2. AppSignal

    Project mention: Why does my vector DB retrieval keep returning duplicate noise for my chat agent, and how to fix it? | dev.to | 2026-10-07

    In langchain-qdrant, LangChain's lambda_mult reaches Qdrant as its diversity, so the direction flips, as an open LangChain bug report records. At 0.5 the two readings coincide; the trap opens when you move it.

    Project mention: 300+ languages doesn't mean what you think: three tiers of code understanding | dev.to | 2026-08-08

    I am not the first person to look at this. aider evaluated stack-graphs and went with tree-sitter tags plus PageRank instead (#534). So did OpenHands (#742) and SWE-agent (#38). Three serious teams reached the same conclusion: too much work, unmaintained upstream, not worth it.
