| Spec score · Build Cache Software | 8.3 (#4) | 7.6 (#15) |
| Deployment | The project publishes Docker images on Docker Hub and Quay.io, documents Docker Compose and Kubernetes examples, and can be built as a standalone Linux binary. | The project provides container images for its components and links to example deployments. |
| License | The repository identifies the project as licensed under Apache-2.0. | The remote execution repository is published under the Apache-2.0 license. |
| Purpose | bazel-remote is an HTTP/1.1 and gRPC server for use as a remote build cache for Bazel and other REAPI clients, or as part of a remote execution service. | Buildbarn implements the Remote Execution protocol to cache and optionally execute build actions remotely. |
| Security configuration | The server supports TLS, configurable minimum TLS versions, and optional unauthenticated read access when authentication is enabled. | The storage daemon supports configurable authorizers for cache and execution operations; its README example uses allow-all authorizers. |

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.
