Your agents need a Devbox | Namespace
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.
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.
scenario 1: DEVBOX
Namespace gives every agent a full VM with all your dependencies](/content/docs/devbox/index.html)
scenario 2: SANDBOX
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).
| Provider | Time (seconds), shorter is better |
|---|---|
| Namespace | 35.50s |
| Daytona | 70.43s |
| E2B | 78.13s |
| Vercel | 80.13s |
| Modal | 99.76s |
Not just Linux.
Devbox supports Mac, Linux, and soon, Windows.
You can't build iOS apps without a Mac

Customer story
“Namespace is the best dev infrastructure tool I’ve used in years. We run everything from our CI to Oz, our cloud agent platform, on Namespace, and I could not recommend it enough.”
Aloke Desai
Head of Product Engineering, Warp
Testimonial
“Namespace's Bazel Remote Execution has unlocked new ways for us to build software in the agentic era. We’ve been early adopters and already see promising performance benefits.”
JP Simard
Director of Mobile Engineering, Ramp
Customer story
“Namespace is really nicely plug-and-play on top of GitHub Actions, but then it also extends it in a really sensible way. It’s a great extension that adds a lot of value on top of what GitHub offers.”
Eelco Lempsink
CTO, Framer
Customer story
“The product is so good. Compared to any other provider I’ve used, it’s just been completely seamless.”
Conrad Irwin
Software Engineer, Zed
Testimonial
“Namespace has been rock-solid for us, the caching feature delivers speeds unmatched by default runners, and the ability to interactively debug runs is a killer. Team is also super responsive, even gave us some tips on how to improve internal infra. Overall very happy!”
Christian Mladenov
Software Engineer, fal.ai
Customer story
“Even though Namespace saved us money, that wasn’t the point. What matters is that it’s reliable and fast. In the end, it’s more about the cost of time than the cost of money.”
Sander van Veen
Developer Experience Engineer, DuckDB
Testimonial
“Been using Namespace for the past year or two, they’ve been absolutely awesome. The service is great, support is great. Just overall great job.”
