Pros
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
  • Under 500 lines of TypeScript - easy to read, fork, and customize
  • Works with any OpenAI-compatible endpoint including local LLMs
  • Configurable breadth and depth give precise control over research cost
  • MIT licensed with Docker compose setup included
  • Strong traction (~19k stars) and a Python community port
Cons
  • Claude-only
  • Newer than LangGraph/CrewAI
  • No hosted UI - command-line only, you run it yourself
  • Requires paid Firecrawl + LLM API keys to be useful at scale
  • Free Firecrawl tier hits rate limits quickly at default concurrency
  • Output quality depends entirely on the model and Firecrawl plan you bring
