Composio review

Composio ranks first because it pairs a large catalog with the most generous free allowance on this list. The Hobby plan includes 100,000 tool calls, 50,000 triggers, unlimited connected accounts and three team members a month without a credit card, and every plan gets the full set of 1,500+ toolkits. Composio handles OAuth consent, token storage, refresh and scopes for each connected account, and exposes tools through SDKs, a CLI for coding agents and a managed MCP gateway. Triggers start background agents from events in connected apps, and the Firewall feature blocks instructions hidden in tool results before the agent reads them. Pro costs $29 a month, includes $29 in monthly credits that do not roll over, and adds unlimited team members and spend controls. The main caveat is the shared OAuth apps: Composio says they work in production but are not built for production scale, so plan to register your own apps before launch.

Who it is for

Developers and startups who want a generous free tier and the fastest path from prototype to agents acting in users' apps.
