Verdict: E2B wins
E2B scores 4.1/5, edging out CrewAI at 4.0/5. AI engineers whose agents execute generated or untrusted code and who want isolated, metered-by-the-second sandboxes instead of running that code on production servers.

E2B
Pros
- + Sub-second sandbox startup in my quickstart runs — create, execute, and read files felt like spawning a process, not provisioning infrastructure
- + Firecracker microVM isolation with outbound network controls kept agent-generated code away from my credentials and services
- + Per-second billing with storage included and a public workload estimator — I could model my ~$166/month usage case before adding the Pro base fee
- + Hobby tier is a real evaluation: $0 with a one-time $100 usage credit, no credit card, 20 concurrent sandboxes
- + Python and JavaScript SDKs with pause/resume persistence and prebuilt dependency templates shorten integration to an afternoon
Cons
- - No local-only mode — the core product assumes cloud connectivity, which fails airgapped requirements without an enterprise deal
- - Per-second CPU/RAM billing punishes sloppy sandbox lifecycle management; idle open sandboxes keep metering
- - Concurrency ceilings (20 on Hobby, 100 on Pro) require paid add-ons for larger fleets — up to 1,100 concurrent on Pro+
- - Deliberately narrow: no agent orchestration, memory, or model routing included — bring your own framework
- - Some integrations (the Vercel AI SDK 7 sandbox package) were marked experimental in the docs at time of writing
CrewAI
Pros
- + Role/goal/backstory abstraction produced clearly differentiated agent behaviour from one underlying model in my three-agent crew test
- + Export-as-MCP-server worked as documented — the crew came up as a tool server a coding agent could call
- + Tracing, OpenTelemetry export and Slack-based human-in-the-loop pauses made a recurring workflow operable
- + The open-source framework installs from PyPI and runs anywhere Python runs; no platform commitment required
- + Studio's AI copilot generated a working workflow skeleton from a plain-language description
Cons
- - Free tier is 50 workflow executions/month — a demo allowance, not a working quota
- - The $25/month Professional tier shown on archived pricing pages is gone; after free there is only a sales conversation
- - Token burn surprised me: a reviewer loop on a three-agent crew cost far more than a single-agent equivalent
- - Hierarchical delegation occasionally looped or duplicated work until I tightened task boundaries
- - SSO, RBAC and PII redaction are Enterprise-gated, so the free tier is unusable for sensitive data
