Install

Flightline is a single Go binary. Install it with go install:

go install github.com/ul0gic/flightline@latest

Requires Go 1.26 or later. App Store Connect work requires a Mac, so that is where Flightline is meant to run (Apple Silicon and Intel are both supported). The binary itself builds anywhere Go does.

The binary lands in $GOBIN (typically ~/go/bin). Make sure ~/go/bin is on your PATH.

Verify the install

flightline --version
flightline --help

go install is the supported install method — a single static binary, no package manager needed.

Build from source

To compile from a checkout instead:

git clone https://github.com/ul0gic/flightline.git
cd flightline
make build
./bin/flightline --version

The binary is at ./bin/flightline. Move it onto your PATH if you want it system-wide:

sudo mv ./bin/flightline /usr/local/bin/flightline

Next steps

1. Generate an App Store Connect API key so Flightline can authenticate.
2. Run your first commands to confirm everything works.
