Get up and running with SpecShip in seconds.

One command grabs the right build for your OS (needs Node 22.5+, below 25)

Section titled “One command grabs the right build for your OS (needs Node 22.5+, below 25)”
Terminal window
# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/selvakumarEsra/specship/main/install.sh | sh


# Windows (PowerShell)
irm https://raw.githubusercontent.com/selvakumarEsra/specship/main/install.ps1 | iex

Already have Node? Use npm instead (works on any version)

Section titled “Already have Node? Use npm instead (works on any version)”
Terminal window
npx @specship/specship        # zero-install, or:
npm i -g @specship/specship

Nothing to compile, no native build — it runs on the Node.js already on your machine (22.5 or newer, below 25) and works the same everywhere. SpecShip is Claude Code only; run specship install to wire it in (project-local by default).

Initialize Projects

Section titled “Initialize Projects”
Terminal window
cd your-project
specship init

That’s it — Claude Code will use SpecShip tools automatically when a .specship/ directory exists.

Next: build Your First Graph, or see the full Installation options.
