Examples

Everything here lives under examples/ in the repository and runs against the same two packages the rest of this documentation describes.

Example	Tiers	What it is for
CMS	both	Two Python packages — free and paid — filling the same three contribution points, on shadcn/ui. The clearest statement of package → extension → plugin → contribution. Runs on this page.
Music store	both	The full model: slots, a contribution point, an extension, a lazy plugin, and a checkbox per plugin on both tiers. Runs on this page.
Astro CMS	both	A SQLite-backed multi-user and multi-site CMS with Astro live collections, Primer, Lexical, Python-packaged extensions and optional x402 paid routes.
Frontend	TypeScript	The smallest thing that is still a platform: two plugins and a slot.
Frontend + backend	both	The same, with a FastAPI backend and a gated slot.
CLI	Python	A command-line host extended by a plugin, with no browser anywhere.
Federation	TypeScript	Plugins fetched from a URL: one that works, one that fails on purpose, and one installed by pasting a link.
Extension	both	One pip install shipping a Python plugin and its UI — and appearing in a server that was already running.

Start with the music store demo if you want to see the model rather than read it — the Plugins panel on its right switches any plugin off while it runs, on either tier.
