Buildless vs Cachix

Buildless is a remote build cache service for teams that want build tools to reuse compiled output rather than repeat compilations. It supports Gradle, Maven, Turborepo, Bazel, CCache, and SCCache, with the maker describing its main integrations as drop-in and requiring no changes to code, the build process, or cloud setup. The docs also list REST/gRPC, Redis (RESP), and GitHub Actions. Its described infrastructure combines Cloudflare edge routing with a Redis-compatible backend through Dragonfly Cloud, plus tunable replication and durable in-memory storage. The Team plan adds premium caching with replication, edge serving, and persistence. Individual / OSS is free, with one project, one user, 3GB of cache, and 100GB transfer. Team is free during the public beta, with five projects, up to 50 users, 10GB cache, and 1TB transfer. Builds are not halted when storage or transfer is exceeded, but overages are charged. Business pricing is TBD and lists private cloud or on-prem options.

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.
