Hosting
Each site runs in an unprivileged LXD container. The control plane never executes customer PHP.
Runtime
Ubuntu 24.04, Nginx 1.26, PHP-FPM 8.1 to 8.4, MariaDB 11.4, Redis 7.4, WP-CLI, and Composer.
Isolation
One container per site. Customer PHP stays unprivileged. Live code is immutable in Git mode.
Regions
Google Cloud regions for the standard fleet, plus a Hetzner budget tier. You can also attach your own node.
What comes next
