Piston is a high performance general purpose code execution engine that safely runs untrusted and potentially malicious code in isolated environments. It exposes a public API and powers web IDEs, Discord bots, and 200+ integrations for arbitrary code evaluation.

Use cases

  • run untrusted user-submitted code safely
  • build an online code execution API for a web IDE
  • evaluate code snippets in a Discord bot
  • execute code in many programming languages from one service
  • self-host a sandboxed code runner
  • power coding challenge and contest platforms

When to choose

  • you need to execute arbitrary code from users in a sandboxed way
  • you want a single API supporting many languages
  • you are building an online judge, playground, or code-eval bot
  • you need a self-hosted alternative to hosted code execution services

When to avoid

  • you only need to run your own trusted code
  • you need heavy GPU or long-running compute workloads
  • you cannot host Linux containers or LXC environments
  • you need per-user persistent state across executions
