Pros
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
  • Roughly 100 lines of Python — trivially readable and hackable
  • Scores 74%+ on SWE-bench Verified despite the minimal design
  • Model-agnostic via litellm, OpenRouter, and Portkey
  • Sandbox-friendly: Docker, Podman, Singularity, Bubblewrap, local
  • Apache 2.0; backed by the SWE-bench and SWE-agent authors
Cons
  • Claude-only
  • Newer than LangGraph/CrewAI
  • No GUI, IDE integration, or hosted product
  • Bash-only tool surface — no built-in browser, search, or planning tools
  • You build your own ops layer (logging, cost caps, retries)
  • Aimed at researchers more than day-to-day end users
