E2B provides secure, isolated sandbox runtimes for AI-generated and agent-driven code, built on Firecracker microVMs that cold-start in under 200ms. The platform's Code Interpreter, AI Sandboxes, and Desktop Sandbox products let LLMs execute Python, JavaScript, Ruby, C++ and other languages with full filesystem, terminal, package management, and browser access for sessions up to 24 hours. Customers include AI labs, agent startups, data teams, and enterprises building code interpreters, deep-research agents, data analysis features, and computer-use agents. SDKs are available for Python and TypeScript and integrate with OpenAI, Anthropic, Mistral, Llama, LangChain, LlamaIndex, and the Vercel AI SDK. Pricing is freemium with Pro and Enterprise tiers and a startups program.
