Spec score 7.9 #8 of 23 in Build Cache Software

What it is

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.

Spec sheet

Purpose
Cachepot is a compiler caching tool that avoids recompilation when possible and stores results on local disk or cloud storage.Read 2 Oct 2026 · github.com
Platforms
The README says prebuilt x86-64 binaries are available for Windows, Linux, and macOS.Read 2 Oct 2026 · github.com
Build integrations
The README describes using Cachepot with Cargo, CMake, and Jenkins, and the official documentation also has GitLab and Concourse CI pages.Read 2 Oct 2026 · github.com
CI security caveat
The GitLab guide warns that compilation output can leak data from the execution environment and says CI secrets should not be treated as secret from that output.Read 2 Oct 2026 · cachepot.cc
Default cache limit
The README says the default local cache size is 10 gigabytes and can be changed with CACHEPOT_CACHE_SIZE.Read 2 Oct 2026 · github.com
Distributed compilation
Cachepot supports icecream-style distributed compilation with automatic packaging of local toolchains.Read 2 Oct 2026 · github.com
Path limitation
For a cache hit, the README says absolute file paths must match, including paths to third-party Rust crates in Cargo's default registry cache.Read 2 Oct 2026 · github.com
Project status
The repository says Cachepot was archived on February 28, 2023 and superseded in favor of upstream sccache.Read 2 Oct 2026 · github.com
Rust limitations
The README says Rust crates that invoke the system linker and incrementally compiled crates cannot be cached.Read 2 Oct 2026 · github.com
Sandbox support
The threat model documents built-in sandbox support using bubblewrap or Docker, with bubblewrap named as the preferred choice.Read 2 Oct 2026 · cachepot.cc
Security caveat
The threat model lists server-side hash verification as a hardening goal and marks it TODO.Read 2 Oct 2026 · cachepot.cc
Security design
The project describes authentication, transport encryption, and sandboxed compiler execution on build servers as security features of distributed compilation.Read 2 Oct 2026 · github.com
Storage backends
The documented storage options include local disk, S3, Redis, Memcached, Google Cloud Storage, and Azure Blob Storage.Read 2 Oct 2026 · github.com
Supported compilers
The README lists gcc, clang, MSVC, rustc, NVCC, and Wind River diab compiler.Read 2 Oct 2026 · github.com

Strong points and limits

Strong points

  • Supports six listed compiler families.
  • Distributed builds package local toolchains automatically.
  • Offers several local and cloud storage backends.
  • Free and open source under Apache-2.0.

Limits

  • Repository archived on February 28, 2023.
  • Some Rust crates cannot be cached.
  • Cache hits require matching absolute paths.
  • Server-side hash verification remains a TODO.

Who it suits

Cachepot may suit teams maintaining builds that use its listed compilers and integrations and can work within its Rust and path-matching limits. Its archived status is important for anyone considering it for a current project.

Verdict

Cachepot documents broad compiler, storage, and build-system support, along with distributed compilation. Its archived status and caching constraints warrant consideration before adopting it.
