homebrew-tap

Homebrew formula for the Vast.ai CLI, which ships a curl | bash installer and a PyPI package but no Homebrew path.

brew install Kilo-Loco/tap/vastai

Use the full name. brew tap plus brew install vastai fails with Refusing to load formula ... from untrusted tap unless you first run brew trust kilo-loco/tap.

Notes

• Upgrade with brew upgrade vastai. The CLI's own vastai update correctly declines on a Homebrew install, but suggests pip and the curl | bash installer, neither of which applies here.
• If you previously ran install.sh, its ~/.local/bin/vastai will shadow this one. Run vastai uninstall first, or check with which -a vastai.
• Apple silicon on macOS 26 or 15 gets a prebuilt bottle and installs in seconds. Anything else builds all 39 resources from source, which pulls ~2GB of toolchain first (cryptography needs Rust, pillow needs six image libraries). Budget several minutes there.
• Intel macOS cannot be bottled: homebrew-core no longer ships Intel bottles for part of the dependency chain, so it is an untested source build.
• Linux is unsupported (depends_on :macos): pillow's setup.py needs a *_ROOT hint per native library there, and after two fix rounds (zlib, then jpeg) the chase was stopped. Linux users should use pip install vastai or the upstream installer.
