Firebox gives AI agents a disposable code sandbox
Firebox presents an API for running code in isolated microVM sandboxes, with examples for creating a sandbox, executing a command, and destroying it.
- For
- Developers running AI-generated code
- Worth noticing
- The example lifecycle shows a sandbox ID, command output, exit code, 29 ms duration, and a final destroyed status.
Field notes
Documentation lays out a three-step API sequence: create a sandbox with vCPU and memory settings, execute a command, then delete it; curl and Python examples are visible, with TypeScript listed as another option. The page says each run receives its own Firecracker microVM and describes timeouts, CPU and memory caps, streamed output, and pause/resume. These are homepage descriptions and examples; the service is labeled “Private pilot — invite only,” so general availability is not established.
