Run AI-generated code in isolated Firecracker microVMs or WebAssembly environments with background jobs, batches, budget limits and execution receipts, hosted
What it is
WBX Sandbox is a complete execution platform for AI agents that runs code securely in isolated environments. It offers two runtime options: Firecracker microVMs for full Linux workloads and lightweight WebAssembly for focused computations. The platform handles background jobs, batch execution of up to 1,000 tasks, automatic retries, cost control through Budget Guard, and provides detailed execution receipts with logs and file hashes.
Developers can connect their agents in minutes using native MCP support for ChatGPT and Claude, a Python SDK, or REST API. The platform manages infrastructure automatically, including timeouts, cleanup and retries, so users can focus on shipping agents rather than managing servers.
WBX runs on refurbished enterprise servers in the EU operated by an internet service provider, offering reliable hardware put to useful work. All pricing is per-second billing for allocated vCPU and memory, with flexible plans from free tier to enterprise dedicated capacity.

- Isolated Firecracker microVMs with own kernel and filesystem
- Background jobs that survive disconnects
- Batch execution with up to 1,000 jobs and dependency passing
