Choose caveman if…

  • caveman is primarily JavaScript; LeanEuclid is Lean.

  • When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content.

When NOT to use caveman

  • When requiring complex and detailed prompts that necessitate more nuanced expression beyond simple, 'caveman'-style sentences.
  • For situations where adherence to formal or specific linguistic structures is mandatory for the task's success.

Choose LeanEuclid if…

  • LeanEuclid is primarily Lean; caveman is JavaScript.
  • Tags unique to LeanEuclid: lean, euclidean-geometry, autoformalization, formalization.
  • Also covers Computer Vision.
  • LeanEuclid ships Docker support for self-hosted deployment.

When NOT to use LeanEuclid

  • Last GitHub push was 228 days ago (slowing maintenance, Nov 25, 2025). Validate activity before betting a new project on LeanEuclid.
  • LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
  • Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
