Installation

Homebrew

brew install kerem-kaynak/tap/pier

From source

Build with make, not go build. The in-VM supervisor must be embedded into the binary:

git clone https://github.com/kerem-kaynak/pier
cd pier
make install

Laptop requirements

• aws CLI v2 and the Session Manager plugin
• git and OpenSSH (already on macOS/Linux)
• Go 1.24+ (only when building from source)

pier doctor checks all of it, plus your AWS auth and account groundwork:

pier doctor
