Announcing pkgmirror: self-host your own Zig mirror

pkgmirror is an open-source, self-hosted Zig toolchain and package mirror service so your builds no longer rely on third-party services or Microsoft GitHub. Mach now hosts its own pkgmirror at pkg.hexops.org. Features Zig toolchain mirroring: acts as a caching reverse proxy for Zig toolchain downloads from ziglang.org Package mirroring (optional) - instead of writing GitHub URLs in your project’s build.zig.zon, use your own server and have it mirror GitHub, Codeberg, or your project host of choice. No more Microsoft-induced downtime harming your builds. Artifact mirroring (optional) - mirror prebuilt binaries and CI artifacts the same exact way. Nominated Zig support - support for Mach’s nominated Zig versions: something less of a moving target than nightly Zig, but more frequently updated than Zig stable releases. Proactive cache warming - automatically fetches all stable and nominated Zig versions, for each OS/arch variant, so that your mirror is ready to go. Automatic LetsEncrypt…
