E2B

E2B (e2b-dev) provides secure, isolated cloud sandboxes for AI agents and AI-generated code, built on a forked Firecracker microVM runtime. The platform ships a REST Sandbox API, JavaScript and Python SDKs, a Code Interpreter SDK, a Desktop Sandbox for computer-use agents, persistent volumes, a custom template build system, and an e2b CLI. The Apache-2.0 licensed core repos — E2B, infra, firecracker, code-interpreter, and desktop — also support self-hosted deployments on AWS, GCP, Azure, or bare Linux. E2B is LLM-agnostic and used by labs and enterprises building code interpreters, deep-research agents, data analysis features, reinforcement-learning environments, and computer-use agents.

E2B publishes 12 APIs on the APIs.io network, including access-tokens API, admin API, api-keys API, and 9 more. Tagged areas include AI, Agents, Code Execution, Code Interpreter, and Sandboxes.

The E2B catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

E2B’s developer surface includes authentication, developer portal, documentation, getting-started guide, API reference, signup flow, engineering blog, and 42 more developer resources.

  data:
  - Firecracker microVM sandboxes that cold-start in under 200ms in-region and run up to 24 hours on Pro
  - Pause, resume, and snapshot sandboxes to persist agent state across invocations
  - Custom sandbox templates built from e2b.toml or programmatic SDK definitions with cached build layers
  - Persistent volumes attachable to any sandbox with a separate Volume Content API authenticated by short-lived JWTs
  - Up to 100 concurrent sandboxes on Pro (expandable to 1,100 with purchase) and up to 20 on Hobby
  - Adjustable per-sandbox CPU and RAM, plus 10-20 GiB of free storage depending on tier
  - JavaScript/TypeScript and Python SDKs for the Sandbox, Code Interpreter, and Desktop products
  - Code Interpreter SDK returns Jupyter-style outputs (stdout, charts, images, html, markdown, latex)
  - Desktop Sandbox boots a Linux desktop with noVNC stream and mouse/keyboard/screenshot primitives for computer-use agents
  - MCP Gateway and MCP server integrations that expose sandboxes as tools to Claude, ChatGPT, and other MCP clients
  - LLM-agnostic — works with Anthropic, OpenAI, Mistral, Llama, and any custom model
  - Built-in integration patterns with LangChain, LlamaIndex, Vercel AI SDK, CrewAI, AutoGen, and Hugging Face
  - Open-source CLI (`e2b`) for template init, build, list, deploy, sandbox connect, and logs
  - Apache-2.0 licensed core; the platform is buildable from the e2b-dev/infra Go monorepo for self-hosting on AWS, GCP, Azure,
    or bare Linux
  - Enterprise BYOC and on-prem deployments with a forked Firecracker microVM runtime in Rust
  - Per-second usage-based pricing on CPU, RAM, and storage with a $100 signup credit
  - Used in production by AI labs, agent startups, and Fortune 100 enterprises; 1B+ sandboxes started and 3.5M+ monthly SDK

description: E2B (e2b-dev) provides secure, isolated cloud sandboxes for AI agents and AI-generated code, built on a forked
  Firecracker microVM runtime. The platform ships a REST Sandbox API, JavaScript and Python SDKs, a Code Interpreter SDK,
  a Desktop Sandbox for computer-use agents, persistent volumes, a custom template build system, and an e2b CLI. The Apache-2.0
  licensed core repos — E2B, infra, firecracker, code-interpreter, and desktop — also support self-hosted deployments on AWS,
  GCP, Azure, or bare Linux. E2B is LLM-agnostic and used by labs and enterprises building code interpreters, deep-research
  agents, data analysis features, reinforcement-learning environments, and computer-use agents.
