Sandboxes aren't enough.
Your agents need a Devbox.

No credit card required.

A full development environment with your codebase, test suite, databases, and network access.

Namespace Devbox
Interactive demo for sighted users: a cloud agent splits a release test matrix across a 10 by 10 grid of devboxes running macOS, Linux, and Windows. The instances boot in a wave and run in parallel; two fail, the agent edits two files and reruns them, and all 100 pass. Filter the fleet by OS or hover an instance to inspect it. The windows sit on a subtle off-white texture.

Devbox vs sandbox.

The difference decides what your agents can actually do.

Namespace gives every agent a full VM with all your dependencies

Your agent just gets a remote code execution environment

Performance is something we obsess about.

In the recent Dax benchmark, based on real-world tasks, Namespace ranked #1 (shorter is better).

It's not even close

Every Devbox runs on the highest single-core performance across Mac and Linux.

Bar chart of Dax benchmark times (shorter is better): Namespace is fastest at 35.50s, 2.0x faster than Daytona (70.43s), 2.2x faster than E2B (78.13s), 2.3x faster than Vercel (80.13s) and 2.8x faster than Modal (99.76s).
