What is Dedalus Labs?

Dedalus Labs is a Y Combinator-backed company building Dedalus Machines — microVMs that boot in 50ms with full Linux, persistent storage, and VM-level isolation. The platform provides production compute infrastructure for AI agents, with per-second billing and scale-to-zero pricing where sleep is free.

What are Dedalus Machines?

A Dedalus Machine (DM) is a full Linux microVM that spins up in 50ms. Each machine has its own guest kernel with hardware-enforced VM-level isolation, persistent storage that survives restarts, and per-second billing. When your machine sleeps, you pay nothing. The API is three operations: create, exec, sleep.

How fast do Dedalus Machines boot?

Dedalus Machines boot in 50ms using snapshot restore, not image pull. This is state-of-the-art as of 2026 and orders of magnitude faster than existing providers. The speed comes from a custom virtual machine monitor (VMM) called the Dedalus Hypervisor, built on the Cloud Hypervisor project.

What isolation model does Dedalus use?

Dedalus uses VM-level isolation, the strongest isolation model available. Each machine gets its own dedicated guest kernel. The host CPU enforces boundaries in hardware via privilege ring transitions (VMX root/non-root) and Extended Page Tables (EPT). This is hardware isolation, not containers or user-space kernels.

How does Dedalus Machines pricing work?

You get 50 free hours of compute per month. The Pro tier starts at $20/month with higher rate limits. You are billed per-second for active CPU time only. When your machine sleeps, you pay $0. Storage is persistent and priced separately from compute.

How is Dedalus different from E2B, Daytona, or Fly.io?

Most providers force a tradeoff: fast startup but restricted environments (V8 isolates, Pyodide), or full sandboxes with slow boot times. Dedalus Machines give you both: a full unrestricted Linux environment with 50ms boot, VM-level isolation, persistent storage, and scale-to-zero billing. No imposed session limits, no garbage collection.

What can I run on a Dedalus Machine?

Anything you can run on Linux. Dedalus Machines include systemd, root access, any package manager, any runtime, any binary. GPU support for ML workloads. Nested virtualization for building your own sandboxes. No restrictions on languages, frameworks, or system-level tools.

Does Dedalus support persistent storage?

Yes. Dedalus Machines serve fully POSIX-compliant filesystems with a 100% pass rate on pjdfstest. Memory, volumes, and compute survive restarts. You can access files even while your machine sleeps. Compute and storage are disaggregated, enabling live VM migrations with zero downtime.
