ComposioFreemium
Gives agents authenticated access to 1,000+ applications, handling OAuth, tool selection, and sandboxed execution so you do not build integrations one at a time.

Composio vs E2B
Pricing, pros, cons, and ideal use cases — side by side.
E2BFreemium
Isolated sandboxes where an AI agent can run the code it just wrote without touching anything you care about.
At a glance
| Composio | E2B | |
|---|---|---|
| Pricing | FreemiumFree tier to get started; paid and enterprise plans are not published on the site and require a demo. | FreemiumHobby is free with $100 one-time usage credits, community support, sessions up to 1 hour, and 20 concurrent sandboxes; no credit card required. Pro is $150/month with customisable sandbox CPU and RAM, sessions up to 24 hours, and 100 concurrent sandboxes, expandable by purchase to 1,100. Enterprise is custom. Compute is billed per second on vCPU, RAM, and storage on top of the plan fee. |

Pros & cons
Composio
Pros
- Eliminates per-integration OAuth work across 1,000+ apps
- Just-in-time tool selection avoids context-window tool bloat
- Sandboxed execution environments for multi-step workflows
- Works with MCP clients including Claude Code and Cursor
- Real free tier for evaluation
Cons
- Paid pricing is not published
- Routing agent credentials through a third party needs a security review
- Another dependency in the critical path of every agent action
- Tool coverage depth varies by application
E2B
Pros
- Real isolation for agent-executed code — the correct security posture
- Sub-second sandbox start times
- Free tier with $100 credits is enough for a genuine evaluation
- Concurrency limits are published and purchasable
- Per-second billing means short runs are genuinely cheap
Cons
- The $150 Pro step is steep relative to the free tier
- Compute is billed on top of the plan fee — the plan price is not your bill
- Long-lived idle sandboxes are the standard way teams overspend
- Developer infrastructure — no value without engineering
- You still own the prompt-injection risk; isolation limits blast radius, it does not prevent bad instructions
Which should you choose?
Composio is built around engineering teams building production agents; E2B leans more toward teams shipping code-interpreter or data-analysis agent features. Shortlist the one whose strengths line up with your biggest constraint.
