Depot vs EngFlow Remote Caching

Depot provides software delivery tools spanning source control, builds, CI runners, sandboxes, caches, and registries. Its container build service is a drop-in replacement for Docker builds, with persistent caching and native x86 and Arm support. Depot CI runs existing GitHub Actions workflows as a programmable, debuggable CI service, while Depot Registry is an OCI-compliant registry for builds, pull-through caching, and other artifacts. Integrations include GitHub Actions, CircleCI, GitLab CI, Google Cloud Build, Travis CI, Bitbucket Pipelines, Buildkite, Jenkins, and AWS CodeBuild. Cache integrations cover Bazel, Go, Gradle, Maven, Pants, sccache, Nx, and Turborepo. Each build and CI run is isolated in a dedicated virtual machine. Depot says communications use TLS and storage is encrypted at rest; it also identifies SOC 2 Type 2 compliance and time-bound, permission-based debugging access. Plans start at $20 a month, billed monthly, with a 7-day trial and no free plan. Developer includes community support; Business includes Slack Connect support.

EngFlow Remote Caching is a remote cache service for reducing repeated builds and test reruns, developer workload, and compute costs. It uses gRPC, cache compression, and Build without the Bytes to limit latency and unnecessary data transfers. A layered cache keeps frequently requested data available, while the Build & Test UI reports cache hit rates, build time, and status in real time. The Free tier supports Bazel and provides in-cluster caching on one machine with 32 CPU cores, running Linux. Enterprise supports Bazel, Goma for Chromium, and Soong for AOSP, as well as in-cluster or external storage such as S3 and GCS. Free is self-hosted; Enterprise can be self-hosted or managed. The service is available for Linux, macOS, Windows, web, and API use. EngFlow says builds run in isolated, encrypted environments with dedicated infrastructure by default, and its solutions receive regular third-party audits against the five SOC 2 principles. Free costs nothing; Enterprise pricing is custom quote. A trial request form is available, with no duration stated.
