docker pull getbusbar/busbar
A FROM scratch image: the static binary plus the provider catalog, ~6 MB
compressed (v1.5.5). Pin an exact version (getbusbar/busbar:1.5.5) or ride
latest; images carry a verifiable build-provenance attestation
(Docker Hub, also on GHCR).
Then follow Getting Started to configure and run it.
curl -fsSL https://getbusbar.com/install.sh | sh
Drops busbar and providers.yaml into the current directory,
no sudo, no global install. Then follow Getting Started.
To install onto your PATH, set the directory for the shell that runs the script, which is the one on the
right of the pipe:
curl -fsSL https://getbusbar.com/install.sh | sudo env BUSBAR_INSTALL_DIR=/usr/local/bin sh.
The Linux builds are glibc: on Alpine or another musl distribution the installer stops and tells you to use
the Docker image rather than installing a binary that cannot run.
brew install GetBusbar/busbar/busbar
Installs the release-signed binary from the tap (Apple Silicon + Intel, and Linuxbrew).
On Homebrew 6+, trust the tap once first: brew tap GetBusbar/busbar && brew trust GetBusbar/busbar.
brew upgrade busbar tracks new releases automatically.
cargo install --git https://github.com/GetBusbar/busbar-admin A small Rust CLI for the admin API: mint virtual keys, list hooks, read config version, and more. The human-facing companion to the admin API SDKs (Python, TypeScript, Go).
Or grab the binary directly
Each archive contains the single busbar binary. You'll also need the
provider catalog, providers.yaml, which the installer
fetches automatically. Builds are produced by the
release workflow and attached to
each tagged release. Source & checksums: latest release.
