Archery is a build system for debugging the building of Pacman packages for Arch and Artix. It uses Docker to achieve a distro-agnostic way to attempt builds. It has a web interface to queue up builds and see their progress.
As a package maintainer for Artix, it is sometimes necessary to try builds both in Artix and Arch locally. This used to be a tedious and error-prone process, particularly for builds that I needed to run on my headless server to satisfy larger RAM requirements. Now with Archery I can easily queue up a build with the parameters I need and wait.
