Run prompts on every model at once. Score. Version. Ship.
Revalvo is a local-first workbench for prompt engineering and LLM evaluation. Run the same prompt against every model in parallel, score responses with 40 built-in evaluators, version prompts like code, and batch-test on datasets — before anything hits production.
