What Is E2B?
E2B provides secure, Firecracker-isolated cloud sandboxes purpose-built for AI agent workloads, letting agents execute code safely with fast sandbox creation, persistence, MCP tool support, and lifecycle APIs. Its 2026 pricing runs a free Hobby tier, Pro at $150/month, Pro+ at $500/month (600 concurrent sandboxes), Pro++ at $1,000/month (1,100 concurrent sandboxes), and Enterprise requiring a $3,000/month minimum — plus per-second compute billing (roughly $0.000014/vCPU-second and $0.0000045/GiB-second).
Its adoption numbers are genuinely substantial for infrastructure aimed specifically at AI agent workloads: approximately 88% of Fortune 100 companies use it, alongside notable AI companies like Perplexity, Hugging Face, Groq, and Manus, having processed over 500 million sandboxes with more than 2 million monthly downloads — real evidence of production-scale trust rather than early-stage experimentation.
It's aimed at developers and companies building AI agent platforms that need secure, isolated code execution infrastructure specifically designed for agent workloads rather than general-purpose cloud compute. See our Coding tools directory for related sandbox infrastructure like Daytona.

E2B Pros & Limitations
What We Like
- Genuinely substantial production adoption — 88% of Fortune 100, over 500 million sandboxes processed
- Purpose-built for agent workloads rather than adapted general-purpose cloud infrastructure
- Free Hobby tier available for initial testing and smaller projects
Limitations
- Higher concurrent-sandbox tiers (Pro+, Pro++) represent significant monthly cost for scaling usage
- Enterprise tier requires a substantial $3,000/month minimum commitment
- Per-second billing requires monitoring to manage costs at high usage volume
