Composio's real strength is managed OAuth across 1000+ tools — genuinely useful if you don't want to handle auth yourself. AgentRaaS doesn't manage OAuth for you; it wraps whatever endpoint or MCP server you already have credentials for in exactly-once execution, dedup, and audit logging. Different trade, worth being honest about which one you actually need.
Composio solves "get my agent authenticated against 1000 SaaS tools." AgentRaaS solves "make sure the call my agent already knows how to make never executes twice."
| Dimension | AgentRaaS | Composio |
|---|---|---|
| Core job | Exactly-once execution, dedup, circuit breaker, audit log | Managed OAuth/credential-refresh across a large integration catalog |
| Integration breadth | ~22 curated services + self-serve Custom Actions (any HTTP endpoint) + MCP Custom Actions (any MCP server — inherits the open MCP ecosystem's growth) | 1000+ tools, managed connections |
| Credential handling | You supply your own API key/token per service | Handles OAuth flows and token refresh for you |
| Self-hosted, free | Yes, unlimited, forever | No self-host free tier |
| Entry price | Free tier, $20/month Pro | Free 20K calls/month, then $29/mo (200K), $229/mo (2M) |
Composio cut its tool-call allowances by roughly 75% and raised overage rates 13–16x. Existing customers, and anyone who signed up before August 15, keep their old plan and limits only through December 31, 2026 — after that, the new pricing applies to everyone. If you're mid-evaluation, that's worth factoring into a decision that's supposed to be about reliability, not a pricing cliff a few months out.
If the actual blocker is "I don't want to build and maintain OAuth flows for 1000 different SaaS APIs," that's real, substantial work Composio has already done. AgentRaaS doesn't attempt to solve that — it assumes you already have a working credential and focuses entirely on what happens after your agent tries to use it.
