Install

Prefer the guided path? Use the Get started wizard.

Pick the surface you want. They share one engine and agree with each other. You can install more than one.

Requirements (everyone)

1. Node.js 26 or newer (node -v should show v26…).
2. A project repository open (TypeScript / JavaScript; git optional but recommended).
3. You do not need to clone the Prism GitHub repo to use published packages.

Choose a surface

After install, run Quickstart or jump to a task guide.

What Prism writes in your project

After the first analysis:

your-repo/
  .prism/
    cache/           index + health history
    consent.json     optional network feature decisions
    bookmarks.json   map bookmarks
    ingest/          artifacts you asked Prism to read
    tools/           tools you consented to install

Let Prism add .prism/ to .gitignore when offered — it is derived output.
