Composio
Connect agents to 1000+ SaaS tools with managed auth and tool registry.
Open source
Best when agents need to act on real SaaS tools (GitHub, Salesforce, Notion) and the team wants managed OAuth, rate limiting, and tool discovery.
Selection advice
Choose Composio when the number of SaaS tools and auth integrations is growing beyond what you can manage with hand-rolled glue. The tool catalog is the product.
Best for
- SaaS tool integration
- managed auth
- tool registry at scale
Not ideal for
- teams that only need a handful of internal APIs
- projects where every tool is custom-built

Minimal implementation shape
Connect an agent to GitHub and Slack through Composio's managed auth layer. Let the agent open issues and post updates without managing OAuth tokens yourself.
