In their own words
BuildFetch Cache
BuildFetch Cache is a remote cache platform intended to reduce build times and CI costs across build systems. It lists native support for Bazel, Gradle, Maven, Sbt, Buck2, Moon, Buildbarn, Ccache, Sccache, Go, Nx, and Turborepo; its listed compiler and language support includes C, C++, Rust, Go, Kotlin, Java, TypeScript, Scala, Assembly, CUDA, Objective-C, Objective-C++, and AMD ROCm HIP. Remote cache outputs can be shared across engineer workstations, CI, and AI agent environments. For Bazel, it supports both gRPC and HTTP remote cache APIs. BuildFetch uses NVMe for ephemeral cache storage and SSD for persistent storage, and its dashboard shows throughput, tail latency, request volume, and storage usage. Scoped project tokens can set read-only or read-write access. The product is offered through BuildFetch Cloud and can also be deployed in Custom Cloud or on-premise Kubernetes environments. The free Open Source plan has caps of 20GB fast cache storage, 50GB network traffic, and 100,000 cache requests, with 45 days LRU retention; those resource caps cannot be exceeded. Paid plans start at $55 a month, and a 45-day trial is listed for Custom. BuildFetch says data is encrypted in transit and at rest.
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.
