Reviewer scorecard
“The most mature AI developer platform. Assistants API, function calling, and the Playground are all well-designed. Documentation is extensive.”
“150ms cold starts for sandboxed code execution. Essential for AI agents that need to run untrusted code safely.”
“Reliability has improved dramatically. The rate limits are generous on paid tiers. The Assistants API is finally stable enough for production.”
“AI agents running code need sandboxing. E2B's micro-VMs are purpose-built for this use case.”
“OpenAI has the largest ecosystem of developers and integrations. Even if other models catch up, the platform moat is real.”
“Safe code execution for AI agents is critical infrastructure. E2B is building the sandbox layer that every agent needs.”
