  • Private local-first alternative to Cursor
  • Any model support via Ollama or OpenAI-compatible servers
  • Import-first approach: reads existing configs from all your tools and converges them before you write YAML
  • No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
  • Portable across tools: single harness.yaml travels with you to every machine and tool
  • Open source and free: no cost beyond existing Claude subscription
