In their own words
bazel-remote
bazel-remote is free, Apache-2.0-licensed open-source software that runs as a self-hosted HTTP/1.1 and gRPC server for Bazel remote caching and other REAPI clients. Cache data can stay on disk with a configured maximum size; least recently used files are removed when that limit is reached. Storage backends include S3, Google Cloud Storage, and an experimental Azure Blob Storage proxy. The server exposes HTTP REST endpoints and REAPI v2 ActionCache, ContentAddressableStorage, Capabilities, and Byte Stream services over gRPC. Zstandard-compressed CAS blobs can reduce network use and increase effective cache capacity. Prometheus metrics are available for HTTP and gRPC endpoints. Deployment options include Docker images, Docker Compose, Kubernetes examples, or a standalone Linux binary, including ARM64 Docker deployments such as Raspberry Pi. Authentication supports .htpasswd-style credentials or mutual TLS; LDAP is experimental, and only one mechanism can be active. TLS settings are configurable. The default permits unauthenticated access, so operators must configure protection.
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.
