What it does

Key features

  • Isolated microVMs: APAC AI-generated code runs without host system access
  • Python/JS/Bash: APAC multi-language sandbox execution via simple SDK
  • Session persistence: installed APAC packages persist within sandbox session
  • Agent framework support: LangChain, LlamaIndex APAC tool integration
  • Custom environments: pre-installed APAC package snapshots for fast starts
  • Filesystem access: APAC sandboxes have isolated file read/write capability
When to reach for it

Best for

  • APAC developers building AI coding assistants, data analysis tools, or AI agents that need to execute user-directed or AI-generated code securely — particularly APAC products where users can instruct AI to write and run code against their data.
Don't get burned

Limitations to know

  • ! Execution cost for APAC high-frequency code runs accumulates vs self-hosted sandboxes
  • ! Network-isolated sandbox limits APAC code that needs external API calls (by design)
  • ! Cold start overhead for APAC short-lived sandbox sessions (custom snapshots mitigate)
Context

About E2B

E2B provides secure cloud sandboxes for running AI-generated code — isolated execution environments where APAC AI coding assistants and agents can execute Python, JavaScript, TypeScript, Bash, and other code without risk of compromising host systems. APAC AI application developers use E2B when building products like AI-powered code interpreters, automated testing agents, or data analysis tools that require running untrusted AI-generated code.

E2B's sandbox architecture runs each APAC code execution in an isolated microVM — AI-generated code cannot access the host filesystem, network resources beyond the sandbox, or other APAC tenant workloads. This isolation model is critical for APAC applications where users can instruct an AI to execute arbitrary code (data science tools, code tutoring platforms, AI debugging assistants).

E2B's Python and JavaScript SDKs allow APAC AI agent frameworks to spawn sandboxes, install packages, execute code, and read output programmatically — a LangChain APAC agent using E2B as its code execution tool can write Python, install `pandas`, run data analysis, and return results to the LLM all within a secure APAC sandbox session. E2B sandboxes persist within a session (installed packages remain available across multiple APAC code executions).

For APAC teams building AI-powered data analysis products (natural language to SQL, CSV analysis, financial modeling), E2B provides the execution layer where Claude or GPT-4o can generate Python code to analyze APAC data, run it securely, and return results — without APAC teams building their own sandbox infrastructure using Docker or gVisor.
