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.
Spawn thousands of tasks across individual, isolated sandboxes in seconds on an elastic backbone.

Sandboxes
Webflow runs AI Code Components builds in Blaxel sandboxes with persistent snapshots. Blaxel reports eliminating mid-build timeouts and a separate state service, with builds resuming in about 25 milliseconds.
Hacker Squad provisions a cloud IDE per workshop attendee using Blaxel sandboxes. Blaxel reports setup falling from 90 minutes to 3 minutes, with hundreds of environments created per event and automatically deleted…
Mendral runs its autonomous DevOps engineer in Blaxel sandboxes across customer repositories. Blaxel reports hardware-isolated runs, credentials injected through an egress proxy and auditable execution without human…
Blaxel introduced label-based access control (ACL) rules for Agent Drives. Users can now assign read or read-write permissions to specific sandboxes, agents, or jobs using metadata labels. These rules, enforced by the server on both direct API calls and mounted drives, allow for granular access control to drive contents based on workload identity.
New feature
Configurable Sandbox Expiration Policies
Blaxel updated its platform to allow developers to modify or remove existing sandbox expiration policies. Users can now programmatically clear TTL settings and lifecycle expiration configurations using the SDK, enabling previously expiring sandboxes to persist indefinitely without needing to recreate the resource.
