Cachix vs Inedo ProGet

Cachix hosts Nix binary caches so teams can share binaries across CI, development, and deployment environments. Its CLI can push binaries, watch a Nix store, and configure Nix to use a cache. The service says its optimizations speed up cache roundtrips, while Cloudflare CDN provides performance and unlimited bandwidth on all plans. When a cache reaches its storage limit, least-recently-used entries are removed; Cachix says it sends a warning email at 85% of that limit. Documentation includes CI guides for GitHub Actions, Buildkite, CircleCI, GitLab CI, Hercules CI, Hydra, and Travis CI. Cachix Deploy uses a pull model to deploy continuously to Nix profiles such as NixOS, nix-darwin, and Home Manager. Teams can assign read or write access, revoke tokens, and require a token for private cache reads and writes; cache entries are signed. Enterprise options include on-premise or self-hosted deployment, SSO, SLA, dedicated premium support, custom deployment, and audit logs. Cachix offers a free plan and a 14-day trial. Listed Starter, Standard, and Pro plans have prices available by contacting Cachix.

Inedo ProGet is a package and container repository for teams that need a central place to manage software packages and Docker images. It supports formats including NuGet, PyPI, Conda, npm, Ruby Gems, Maven, Chocolatey, PowerShell/DSC, RPM/Yum, Debian/apt, and Alpine/APK. Teams can cache upstream packages, set approval workflows, scan for vulnerabilities, identify licenses, and block packages that fail their requirements. ProGet can host private Docker registries and scan container contents to help control which images reach production. It integrates with CI/CD tools and includes a CLI and HTTP API for component identification and SBOM publishing. Deployment options include self-hosted Windows or Linux installations and cloud VM or container environments. Identity and operational features include LDAP, SAML, load balancing, high availability, and feed replication for disaster recovery. The free edition permits commercial use and unlimited feeds for private packages and Docker, but has limited security and compliance features. Paid annual plans start at $2,395/year. Licensing is per server, and test or development installations require separate licenses.
