In their own words
Cachix
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.
Nexspence
Nexspence is a self-hosted artifact repository manager positioned as a replacement for other artifact repository managers. It supports 15 formats, including Maven, Docker, npm, PyPI, Go Modules, NuGet, Helm, Cargo, Apt, Yum, Conan, Raw, Conda, and Terraform. Hosted, Proxy, and Group repository types are available across formats, with format-specific exceptions. A one-command migration streams repositories, users, and artifacts from a live Nexus instance and is described as pausable and conflict-safe. Storage can use MinIO, AWS S3, Wasabi, or a local filesystem, with per-repository blob-store assignment. Identity options include OIDC/SSO providers, just-in-time provisioning, and group-to-role mapping. Security controls include LDAP, API tokens, JWT, fine-grained RBAC, and SSRF-protected outbound fetches. OSV.dev scanning covers Maven, npm, PyPI, and Cargo; Docker and OCI scanning requires an operator-supplied Trivy installation. Deployment options include Docker Compose, Helm/Kubernetes, and native packages or archives for Linux, macOS, and Windows. Nexspence is free at free and licensed under GNU AGPL v3 or later.
