Summary

Cachepot is an open-source compiler caching tool for Linux, macOS, Windows, and self-hosted environments. It stores compilation results on local disk or cloud storage so builds can reuse results instead of recompiling when possible. The documented compiler list includes GCC, Clang, MSVC, rustc, NVCC, and Wind River Diab. Distributed compilation can package local toolchains automatically, and storage options include local disk, S3, Redis, Memcached, Google Cloud Storage, and Azure Blob Storage. Build integrations include Cargo, CMake, Jenkins, GitLab, and Concourse CI. Its distributed-compilation security design describes authentication, encrypted transport, and sandboxed compiler execution on build servers; bubblewrap is the preferred sandbox option over Docker. The default local cache limit is 10 gigabytes and can be changed with CACHEPOT_CACHE_SIZE. There are notable constraints: Rust crates that use the system linker and incrementally compiled crates cannot be cached, while cache hits require matching absolute paths. The repository was archived on February 28, 2023, in favor of upstream sccache. Cachepot is free under the Apache-2.0 license.

Who it is for

Cachepot may suit developers and build teams looking for a self-hosted or local compiler cache with distributed compilation. Its archived status and Rust and path limitations are important considerations.

What is good

Free and Apache-2.0 licensed.
Supports GCC, Clang, MSVC, rustc, NVCC, and Diab.
Offers local and cloud storage backends.
Distributed compilation packages local toolchains automatically.
Includes documented sandboxing and transport encryption.

What to know first

Repository was archived on February 28, 2023.
Some Rust crates cannot be cached.
Cache hits require matching absolute file paths.
Server-side hash verification is listed as a TODO.

Verdict

Cachepot documents broad compiler, storage, and build-system support, along with distributed compilation. The repository is archived, and its documented Rust and path constraints may affect whether it fits a build workflow.
