In their own words
FosterStack
FosterStack is a self-hosted remote build cache server intended as a replacement for Develocity Build Cache Node. It supports Gradle and the Apache Maven Build Cache Extension remote HTTP mode, although Maven acceptance coverage is in progress. Size-capped LRU eviction frees space for new entries. HTTP Basic Auth over TLS uses constant-time credential comparison, and credentials are not logged. Prometheus metrics and a read-only status page report hit rates and cache size against its cap. Deployment options are a Docker image or static binary; release binaries are available for Linux and macOS on amd64 and arm64. Windows is not built or planned. The MIT-licensed core has signed releases with SLSA provenance, and security patches are included in the free tier. The maker says the free core makes no outbound connections and collects no telemetry or usage data. FosterStack identifies the product as v0.1 and says nobody outside its own work is yet running it in a production build pipeline. The full self-hosted server is free. Team, Business, and Compliance plans are described but not yet available, with listed prices of $49.00 per month, $199.00 per month, and $499.00 per year, respectively.
NativeLink
NativeLink brings remote build caching, remote execution, and observability into a Rust-native platform. Its content-addressed cache deduplicates build artifacts so teams, CI systems, and agents can reuse prior results. Remote execution spreads compilation and tests across worker fleets on AWS, GCP, or bare metal, with GPU, ARM, and Apple Silicon support. Listed build systems include Bazel, Buck2, Siso, Soong, Pants, Goma, BuildStream, and CMake through recc. CI integrations include GitHub Actions, GitLab, Buildkite, and Jenkins; other listed connections include AWS, GCP, Azure, S3, GCS, and Redis. The product also lists integrations with AI coding platforms. It can run as a self-hosted Rust binary. Clients support Linux, macOS, and Windows, while servers support Linux and macOS. The free Open Source tier includes community Slack support. Most of the monorepo uses FSL-1.1-Apache-2.0, but metrics and remote persistent workers are Business Source License modules requiring Enterprise or a separate license for shared production use.
