Converting Docker-based Actions to JavaScript/TypeScript
Best alternatives to BLAST in 2026
Running code in an isolated, disposable environment — a sandbox — is something AI agent builders, CI systems, and security teams all need constantly, but every sandboxing tool tends to lock you into one specific backend, just Docker or just a VM. BLAST is a small tool from Stanford's MAST research group that gives you one simple command to spin up a sandbox on whichever backend you actually have available. BLAST is an open-source sandbox orchestration layer, shipped as a single binary around 7 MB, that abstracts Docker, SmolVM, and Hypeman behind one unified API for forking and running sandboxed commands. It handles resource scheduling, snapshot persistence, and monitoring automatically, and the whole codebase is intentionally minimal, around 3,500 lines of Rust. MIT-licensed and free.
