The low-cost cloud sandbox where AI agents actually live
Pay for vCPU, memory and disk separately while the sandbox runs; when it sleeps or is deleted the compute meter stops and you are left with disk cost only.
Launch Claude Code, Codex, OpenClaw, OpenCode, Hermes, Grok or your own Docker image, each in its own tenant-isolated sandbox.
Files survive sleep, restarts and weeks of inactivity, and agents can be attached to cron-style schedules so work runs unattended.
Expose individual ports publicly, attach your own domain, or keep everything behind an API key on an authenticated URL.

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.

SpecialistThe AI developer cloud for GPU pods, serverless inference and clustering
SpecialistRuns serverless Python containers optimized for AI model inference and batch jobs rather than persistent agent sandboxes.

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.

SpecialistRobust TypeScript framework for agent workflows and tools, but requires writing custom integration code instead of pre-built connectors.


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.

SpecialistCloud browsers and web APIs for AI agents
SpecialistComprehensive enterprise LLM gateway and guardrails, but focuses more on model routing than third-party SaaS tool execution.

SpecialistSelf-hosted infrastructure platform for provisioning secure cloud development workspaces and governing AI coding agents.

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