Installation

Labcoat publishes native binaries for macOS and Linux on arm64 and x86_64.

curl -fsSL https://labcoat.sh/install | sh

The installer downloads the latest cli-v* release, verifies its SHA-256 checksum, and writes labcoat to ${LABCOAT_INSTALL_DIR:-$HOME/.local/bin}.

Install a specific version

curl -fsSL https://labcoat.sh/install | sh -s -- 0.7.0

Compilation prerequisites

Contract compilation requires an LLVM Clang build with a WebAssembly backend.

# macOS
brew install llvm

# Debian or Ubuntu
sudo apt install clang wasi-libc

Then verify the complete environment:

labcoat doctor

If $HOME/.local/bin is not already on PATH, the installer prints the exact export command to add.
