AgentoolRank

AgentoolRank is a free directory of 593 open-source AI agent tools: agent frameworks, coding agents, MCP servers, RAG and memory tools, evaluation and observability tools, browser agents and voice agents. Instead of ranking by total GitHub stars, it ranks tools by recent activity: 30-day star growth, commits in the last 90 days, releases in the last 6 months and issue response time. The data refreshes daily from the GitHub API, so you can see which tools are actually maintained before you build on them. Every tool has its own stats page, an alternatives page and side-by-side comparisons (for example LangGraph vs CrewAI). You can also query the data from Claude, Cursor or any MCP client through a public MCP server and JSON API. It is free to browse with no signup. If you make an open-source AI agent tool, you can submit it for free review.
