cachepot vs EngFlow Remote Caching

Cachepot is a compiler caching tool for Linux, macOS, Windows, and self-hosted environments. It keeps compilation results on local disk or cloud storage so a build can reuse them rather than compile again when possible. The documented compilers include GCC, Clang, MSVC, rustc, NVCC, and Diab. Cachepot can also distribute compilation in an icecream-style setup, automatically packaging local toolchains. Storage choices include local disk, S3, Redis, Memcached, Google Cloud Storage, and Azure Blob Storage. Build integrations include Cargo, CMake, GNU make, Jenkins, and GitLab CI. The project describes authentication, encrypted transport, and sandboxed execution on build servers as security features; bubblewrap is its preferred sandbox option, with Docker also supported. The default local cache limit is 10 gigabytes and can be changed with CACHEPOT_CACHE_SIZE. Rust crates that invoke the system linker and incrementally compiled crates cannot be cached, and cache hits require matching absolute paths. Cachepot is free and open source under Apache-2.0, but its repository was archived on February 28, 2023, in favor of upstream sccache.

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.
