Install

anchor ships as a single self-contained binary. You don’t need .NET installed to run it.

Linux and macOS

curl -fsSL https://raw.githubusercontent.com/fuseraft/anchor/main/install.sh | bash

The script downloads the latest release for your platform and installs anchor to ~/.local/bin. Pass --system to install to /usr/local/bin instead (it uses sudo if needed):

curl -fsSL https://raw.githubusercontent.com/fuseraft/anchor/main/install.sh | bash -s -- --system

If ~/.local/bin isn’t on your PATH, the script prints the line to add to your shell’s rc file.

Both install scripts check the download against the release’s SHA256SUMS and refuse to install an archive that doesn’t match.

anchor installed this way updates itself. Once a day, a session checks for a new release and downloads it, checked against the same SHA256SUMS, and the next time anchor starts it runs the new version. "autoUpdate": false in the config turns this off; to update by hand, run the install command again. A copy installed by Homebrew, Scoop or winget isn’t touched: anchor tells you a new release is out and leaves the update to the package manager.

Windows

irm https://raw.githubusercontent.com/fuseraft/anchor/main/install.ps1 | iex

This installs anchor.exe to %LOCALAPPDATA%\anchor\bin and adds that folder to your user PATH. Open a new terminal afterwards. On ARM64, the x64 build runs under emulation.

Windows asks before every shell command

anchor’s shell safety rules read commands as bash, but Windows runs them with cmd.exe, which splits and quotes differently. Until the rules understand cmd and PowerShell, Windows builds never treat a command as read-only and never offer “always allow” for commands. See Safety and approvals.

With a package manager

Homebrew on macOS and Linux:

brew install fuseraft/tap/anchor

Scoop on Windows:

scoop bucket add fuseraft https://github.com/fuseraft/scoop-bucket
scoop install anchor

brew upgrade anchor and scoop update anchor update it.

From a release

Download an archive for your platform from the Releases page, extract it, and put anchor on your PATH. Builds are published for linux-x64, linux-arm64, osx-x64, osx-arm64 and win-x64.

Each release lists the archives’ checksums in SHA256SUMS, and carries a signed build provenance attestation that ties every archive to the GitHub Actions run that built it. With the GitHub CLI, check one with:

sha256sum --check --ignore-missing SHA256SUMS
gh attestation verify anchor-<version>-linux-x64.tar.gz --repo fuseraft/anchor

From source

Building needs the .NET 10 SDK. The tests also need git and python3.

git clone https://github.com/fuseraft/anchor.git
cd anchor
./build.sh      # runs the tests, then publishes bin/anchor for this machine

Check it works

anchor --version

Next, set an API key and start a session.
