Relationship with Homebrew
zerobrew is more of a performance-optimized client for the Homebrew ecosystem. We rely on:
- Homebrew's formula definitions (homebrew-core)
- Homebrew's pre-built bottles when available
- Homebrew's package metadata and infrastructure
Our innovations focus on:
- Content-addressable storage for deduplication
- APFS clonefiles for zero-overhead copying
- Source build fallback using Homebrew's Ruby DSL
zerobrew is experimental. We recommend running it alongside Homebrew rather than as a replacement, and do not recommend purging homebrew and replacing it with zerobrew unless you are absolutely sure about the implications of doing so.
Project status
- Status: Experimental, but already useful for many common Homebrew formulas.
- Feedback: If you hit incompatibilities, please open an issue or PR.
