Every release binary, with checksums. If you just want it installed, the one-line installers do this for you.

Current release: v0.9.1. Binaries are hosted on GitHub Releases. They are unsigned — verify the SHA-256 below before running, especially on a machine you did not build them on.

No linux-arm64 build yet: it compiles, but the V8 startup snapshot cannot be cross-compiled, so it needs a native ARM builder. SHA256SUMS, LICENSE, NOTICE and THIRD_PARTY_LICENSES.md ship with every release.

Verify

macOS and Linux — check every file the release published:

curl -fsSLO https://github.com/YawLabs/oam/releases/download/v0.9.1/SHA256SUMS
shasum -a 256 -c SHA256SUMS --ignore-missing

Or a single file, compared against the line above:

shasum -a 256 oam-aarch64-apple-darwin

Windows (PowerShell):

Get-FileHash .\oam-aarch64-pc-windows-msvc.exe -Algorithm SHA256 | Format-List

Get-FileHash prints uppercase; the sums above are lowercase. Compare case-insensitively, or pipe through .Hash.ToLower().

After downloading

The file is the whole runtime — there is nothing to unpack. On macOS and Linux mark it executable and put it on your PATH:

chmod +x oam-aarch64-apple-darwin
mv oam-aarch64-apple-darwin ~/.local/bin/oam
oam --version

macOS quarantines files downloaded by a browser, and these are unsigned, so Gatekeeper will refuse the first run. Clear the attribute:

xattr -d com.apple.quarantine ~/.local/bin/oam

Installing a specific version

The installers take OAM_VERSION — a release tag, including the v. Unset, they resolve the latest release.

macOS and Linux:

curl -fsSL https://oamjs.org/install.sh | OAM_VERSION=v0.9.1 sh

The variable has to be on sh, not on curl — curl is a different process and would not pass it along.

Windows:

$env:OAM_VERSION = "v0.9.1"; irm https://oamjs.org/install.ps1 | iex

Two related knobs: OAM_INSTALL_DIR changes the target (default ~/.oam/bin, or %LOCALAPPDATA%\oam\bin), and OAM_INSTALL_BASE points at a mirror instead of GitHub Releases. Whatever the source, the installer still verifies against the published SHA256SUMS and refuses a mismatch.

An existing install updates itself with oam self-update, which re-runs this installer and performs the same verification.

All releases

Older versions, with notes and their own checksums, are on the releases page.
