BuildGrid vs cachepot

BuildGrid has no write-up on Specifiction yet; its figures are above.

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.
