[Docs](https://clayjs.com/docs) · Script tag # The script tag The script tag, versioned URLs, and loading plugins through the query string. ```html ``` Every clayjs URL carries a version, because a saved document hardcodes its script tag and there is no way to reach it afterwards to change it. Two forms: | URL | What it serves | | --- | --- | | `/v1/clay.js` | The newest 1.x release. Rolls forward with fixes and features, never across a major version. | | `/1.0.0/clay.js` | That exact release, forever. Cached for a year as immutable. | | `/v1/clay.standalone.js` | The whole library in one file, for a page that must load with no network. Same query params. Details on [Offline](https://clayjs.com/docs/offline). | Use `/v1/` unless you have a reason not to. Both forms exist for every satellite, so `/v1/clay-ui.js` and `/1.0.0/sap.js` work the same way. Published versions are listed at [versions.json](https://clayjs.com/versions.json). There is no unversioned URL: `clayjs.com/clay.js` was retired at 1.0 and returns 404. The default build includes the save lifecycle and rich text (`editable`). Plugins load conditionally through the URL, in the browser only: | Param | Meaning | Example | | --- | --- | --- | | `plugins` | Comma-separated plugins to load | `clay.js?plugins=sync,undo` | | `exclude` | Remove a default-on plugin | `clay.js?exclude=richclay` | Loadable plugins: `richclay` (default on), `source` (default on), `indicator`, `sync`, `sortable`, `undo`, `cms`, `quickcrop`, `upload`, `people`, `wire`, `ai-edit`, `demo`. Turn a default-on plugin off with `exclude=`. Seven have a checkbox in the configurator; ask for the rest by name. The [configurator](https://clayjs.com/#configure) composes this URL for you. Everything else is a separate library with its own script tag: see [Advanced](https://clayjs.com/advanced) and [Plugins](https://clayjs.com/plugins). npm builds for bundlers live at [@panphora/clayjs](https://www.npmjs.com/package/@panphora/clayjs). For a page with no network at all, [the standalone build](https://clayjs.com/docs/offline) is every module in one downloadable file.
