About Namespace

Namespace is a commercial infrastructure service that speeds up the build, test and development workflow of software teams. It runs on its own vertically integrated stack, including custom hardware, a hypervisor and a scheduler, and offers fast coding, build and test environments across Mac, Windows and Linux.

Products include Devboxes, which are development environments aimed at AI coding agents, and a runner service that works as a drop-in replacement for GitHub Actions runners with added observability. Build acceleration is offered for Docker, Bazel, Turbo and Nix, and the company has announced a partnership to give Cursor's cloud agents a full computer.

Namespace is a hosted service that can be started without a credit card, with documentation, a changelog and a status page, and pricing published on its pricing page. It is aimed at engineering teams whose CI queues and build times have become a bottleneck, including teams that build iOS, Rust or monorepo projects.
