The perpetual sandbox platform
Last verified:
Blaxel is the perpetual sandbox platform for AI agents that need to run code fast. Unlike traditional sandboxes that expire or suffer from cold starts, our sandboxes automatically scale to zero after 1s of inactivity and resume in under 25ms with full memory state preserved — allowing you to keep millions of secure sandboxes on standby indefinitely. We also co-locate your agent logic alongside these sandboxes to eliminate network overhead, delivering near-instant latency for end users.
