EvoScientist vs openevolve

The two are close in size: 4.6k stars for EvoScientist, 7.3k for openevolve. Over the days we have tracked them EvoScientist moved +7.2% and openevolve +12.8%, so openevolve is growing faster right now.

openevolve leads on model freedom and setup ease. EvoScientist does not take any axis by a clear margin.

Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.

Where they stand today

Auto-distills a growing memory/knowledge graph into reusable AutoSkills and a multi-agent research loop, enabling long-running self-evolving AI scientists.

Six axes, head to head

Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.

Which one to pick

Pick EvoScientist if…

Self-evolving research — pick EvoScientist when you want an opinionated, multi-agent system that autonomously builds a persistent knowledge graph and drafts reusable skills for iterative scientific workflows.

Runs in cli, web-app. Works with byok, openai, anthropic, other-fixed.

Pick openevolve if…

Research-grade reproducibility — pick this when you need deterministic, scientific-grade autonomous algorithm discovery and hardware-aware code optimization with flexible local or cloud LLM backends.

  • Model freedom: Any provider & local (5/5 against 3/5)
  • Setup ease: One-command start (5/5 against 3/5)
Runs in cli. Works with byok, openai, anthropic, gemini, local-ollama.
