FlakeHub Cache replaces traditional Nix binary caches with a unified, identity-aware cache featuring fine-grained access controls, integrating with GitHub Actions, GitLab CI, Microsoft Entra ID, and AWS IAM via JWTs. Private flakes allow teams to securely share Nix expressions without exposing sensitive code, published only from trusted CI systems. Both features use federated authentication and a policy engine supporting IP restrictions, geo-embargoes, and role-based access. FlakeHub also enables rapid deployment of pre-evaluated closures to NixOS, nix-darwin, and Home Manager environments without requiring Nix on the target system. Pricing is $20 per organization member per month with storage and bandwidth included during an introductory period. ## Full article daily.dev links to this article rather than hosting it.
