Trusted by AI leaders. Used by 65% of the Fortune 500. Why CrewAI Open Source? CrewAI is built in the open to make multi-agent systems available to all. Teams have the freedom to create, orchestrate, and scale agents without barriers. Backed by more than 100,000 developers, CrewAI sets the standard for transparent, reliable, and enterprise-capable AI. Planning Planning agent for tasks CrewAI agents can now plan through long-running, complex tasks and recover automatically when errors get in the way. ![69a111972d2e0bbcc6adbbcf Planning](https://crewai.com/_next/image?url=https%3A%2F%2Fimages.ctfassets.net%2Frmv9a2eqdsyw%2F3cXllr4YlasQkEpLS28rxI%2F8142f479ef14eaddefbc07a4a82ec061%2F69a111972d2e0bbcc6adbbcf_Planning.avif&w=3840&q=75) Tools 100s of open-source tools out of the box CrewAI provides AI agents with hundreds of open-source tools out of the box — search the Internet, interact with websites, query vector databases, run code, and much more. With first-class support for MCP (Model Context Protocol), Custom MCP Servers, and native sandbox tools for E2B and Daytona, agents can safely execute code and call any tool you need, anywhere. ![69a111972d2e0bbcc6adbb51 Tools](https://crewai.com/_next/image?url=https%3A%2F%2Fimages.ctfassets.net%2Frmv9a2eqdsyw%2F6jIU7JjyfjEygrByFZBCgD%2F98a10c8f9f0a6059685f13fad4792cfc%2F69a111972d2e0bbcc6adbb51_Tools.avif&w=3840&q=75) Memory Sophisticated memory-management CrewAI’s memory system is built for real production agents going beyond search-backed storage, acting as a cognitive layer that intelligently remembers, resolves contradictions, forgets intentionally, and knows when it lacks context. Updated for extreme performance, simplicity, and bleeding edge workflows.

It lets users replay from specific steps, fork workflows, and run tasks with different inputs without starting from scratch. [Read docs](https://docs.crewai.com/en/concepts/checkpointing#checkpointing) ![Checkpointing](https://crewai.com/_next/image?url=https%3A%2F%2Fimages.ctfassets.net%2Frmv9a2eqdsyw%2FBkvsOx1owVtx8ZjzqvJmh%2F889ae839ea1717a6571a70e04f64e870%2FScreenshot_2026-05-19_at_4.55.29%25C3%25A2__PM.png&w=3840&q=75) Agent-to-Agent (A2A) Connect Crews with the A2A protocol Run crews, flows, tasks, tools, knowledge, memory, and LLM calls asynchronously with native async/await support. Streaming results flow back in real time from flows and crews, and async context managers make resource cleanup automatic. Write the orchestration you want — CrewAI handles the concurrency.
