Dedalus Labs is a technology company building persistent Linux virtual machines for AI agents. Its platform provides full Linux environments that start in under 50 milliseconds while preserving filesystem and runtime state between sessions. Unlike traditional sandboxes that may need to pull images, start runtimes, or install dependencies, Dedalus Machines are designed to avoid cold starts.

The service offers kernel, memory, and filesystem isolation, with root access inside each sandbox. Dedalus describes its VM-level isolation as a stronger boundary than Docker containers or V8 isolates and says it is suitable for running untrusted code. Each machine provides a complete Linux environment intended to give agents flexibility and persistent access to their work.

Pricing is based on active compute time, with no charges for idle periods. Dedalus Labs invites users to join its waitlist and offers documentation, product details, and pricing information. The company is backed by Y Combinator and is based in San Francisco, California.
