AgentoolRank

AgentoolRank is a free directory of 593 open-source AI agent tools, including agent frameworks, coding agents, MCP servers, RAG and memory tools, evaluation tools, browser agents and voice agents. Tools are ranked by recent GitHub activity rather than total stars: 30-day star growth, commits in the last 90 days, releases in the last 6 months and issue response time, refreshed daily. Each tool has a stats page, an alternatives page and side-by-side comparisons, free with no signup. A public MCP server and JSON API let AI assistants query the data.
