Prebuilt aether binaries are published for macOS, Linux, and Windows on amd64 and arm64. Every download is verified against the release’s checksums.txt before it is installed.

macOS and Linux

The script detects your OS and architecture, verifies the checksum, and installs aether to /usr/local/bin (using sudo only if that directory isn’t writable). To install somewhere else, set AETHER_INSTALL_DIR:
To upgrade, run the script again — it always installs the latest release.

Homebrew (macOS)

This taps Aether-Runtime/aether and installs the aether cask in one step. The cask is macOS-only; on Linux, use the install script above. To upgrade later:
Use the fully qualified name in both commands. Since Homebrew 6.0, content from non-official taps must be trusted before it loads, and naming the cask in full grants that trust for this cask alone. The short form brew upgrade aether fails with Refusing to load cask ... from untrusted tap.

Windows

The script detects your architecture, verifies the checksum, installs aether.exe to %LOCALAPPDATA%\Aether\bin, and adds that directory to your user PATH. To install somewhere else (skipping the PATH update), set AETHER_INSTALL_DIR first:
To upgrade, run the script again — it always installs the latest release.
Windows binaries ship starting with the first CLI release after v0.1.8. Until that release is published, this command fails with a download error.
