What is Caliper?

Caliper runs your real coding agent with and without your skills, MCP servers and rules, then shows which ones improve results and what they cost in tokens. Supports Claude Code, Codex, Pi and Hermes.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what Caliper does well

  • Evidence instead of guesses
  • Tracks token cost

Cons: where it falls short

  • Developer-focused CLI
  • Runs take time and tokens
