Namespace

Developer infrastructure company founded in Zurich in 2022 that runs faster GitHub Actions runners, remote build caches, and macOS and ARM machines for teams and coding agents.

7.9/10
Overall Score
Recommend

Namespace was founded by a former Google principal engineer who helped build Boq, and it brings Google-style build infrastructure to CI runners, caches, and dev environments.

Best for

Engineering teams that need fast Linux, ARM, macOS, and Windows runners with remote caching, including mobile teams with heavy iOS builds.

Not ideal for

Small teams with light CI needs that are well served by free GitHub minutes, or buyers who want simple per-minute prices without compute units.

Verdict

Namespace is worth using for teams with heavy CI across Linux, ARM, macOS, and Windows, especially mobile and infrastructure teams. Its caching and runner speed suit companies where build time slows releases. Light CI users can stay on GitHub's own runners.

Review Excerpts

Below are excerpts from public reviews. Our team scoured public reviews, forums, and chat rooms to get a balanced view of customers' experience with this company. Paid reviews and pay-for-play sites such as Clutch were excluded.

How it's used

“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 at Framer, company testimonial published by Namespace · namespace.so
What people like

“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.”

Mitchell Hashimoto, Creator of Ghostty, company testimonial published by Namespace · namespace.so
What people don't like

Namespace counts macOS time at a 10x multiplier and Windows at 2x in its unit minutes, so iOS-heavy teams use up included minutes far faster than Linux teams.
