Garnix, the Nix‑based CI service, announced it will cease operations on July 15th 2026. The team said the platform is being absorbed by Shopify, and the hosted service will be discontinued. Users must retrieve any stored build artifacts before the shutdown, as all data—including caches and logs—will be erased on that date. Customers relying on nightly builds should plan migration now.

The decision follows years of community‑driven development funded through an Open Collective, during which Garnix became a go‑to for reproducible macOS builds in the Nix ecosystem. By open‑sourcing its codebase, the founders hope developers can self‑host or spin up shared instances, preserving the workflow that many have integrated into CI pipelines, and maintain the same level of cache sharing across projects.

Existing users must migrate to alternative CI providers or deploy their own Garnix instance before the cutoff. The open‑source release includes the full build orchestration stack, allowing teams to replicate the original environment on‑premise. Without immediate action, projects relying on Garnix’s macOS runners will lose a reliable build target, forcing a redesign of their deployment pipelines. Teams can also contribute improvements back to the repository.
