Give your AI agents secure, authenticated access to 1,700+ apps
A large catalog of pre-built integrations spanning productivity, CRM, support, engineering, finance, HR, and e-commerce apps, each exposing callable actions to your agent.
Composio runs OAuth flows, stores and refreshes credentials, and enforces per-action permission scopes so agents act only where you allow them.
One managed MCP endpoint that connects Claude, ChatGPT, Codex, Cursor, and other MCP clients to your entire tool catalog in a few clicks.
Start background agents from events occurring across connected apps, so work can begin without a user prompt.

Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.

Free / Open-sourceExceptional open-source gateway for LLM provider routing, but lacks Composio's extensive library of SaaS tool integrations and auth.


Free / Open-sourceOpen-source MCP gateway and pay-per-call catalog, but offers less extensive managed authentication workflows than Composio.
#3
Free / Open-sourceThe TypeScript framework for building, deploying, and observing AI agents

Powerful universal API infrastructure for connecting agents to B2B data, but focuses more on unified SaaS data than tool execution.

Excellent managed authentication and event triggers for agent workflows, but less specialized around native MCP gateway protocols.
SpecialistComprehensive enterprise LLM gateway and guardrails, but focuses more on model routing than third-party SaaS tool execution.
The low-cost cloud sandbox where AI agents actually live

Self-hosted cloud development environments and AI coding agents for enterprise teams

SpecialistFlexible Python agent framework with built-in tools, but less focused on acting as a standalone universal integration middleware.

Provides unified web data and tool APIs for agents, but lacks the deep multi-app authentication management of Composio.

Standardized API access layer for AI agents, but supports a narrower ecosystem of pre-built third-party tool integrations.
