Composio is an AI integration platform designed to speed up building of smart agent systems. To that end, it lets users connect over 250 apps with a single line of code.

Furthermore, Composio supports all the tools you already use — Gmail, GitHub, Slack — acting as a bridge that makes building of AI agents faster. In fact, it lets LLM agents talk with these services via function calls. You can think of it like handing your AI a toolbox and saying – “Go build.” Cause that’s how it works, with engineers reporting 30-40 percent fewer errors when using Composio to structure calls to third-party services.

As noted above, Composio is made primarily for developers. That means you install an SDK, type a command, and boom — a Gmail tool, a GitHub tool, even custom APIs you wrote. It can sing along popular frameworks like LangChain, CrewAI, Autogen, and others . So instead of wrestling with OAuth tokens or messing up JSON, you spin up agents in minutes — not days.

Composio also cares about trust and it’s SOC II compliant. It logs every action and lets teams set role-based access for safety. For what it’s worth, big companies like 11x AI and UC Berkeley’s Gorilla vouch for it — reportedly saving hundreds of engineering hours and landing multimillion-dollar deals .

Now, we should add that Composio is not the only game in town, with its competitors including Arcade.dev and OpenAI Swarm, as well as self-rolled frameworks. But Composio’s edge is its huge out-of-the-box library that includes more than 250 ready-made tools. That’s bigger than many rivals. Plus, it supports custom tool import via OpenAPI specs, so you’re never boxed in.

So the bottom line is – if you’re a developer looking to build AI agents, this may be the tool you need.
