Spectrum
Browser UI for trying Prism without installing an extension.
Spectrum is the local browser version of the Prism interface — for trying it without an extension, and for developing Prism itself. It indexes the repository selected in Dispatch, not the Prism checkout.
Running it
From a clone of the repository:
bun install
bun run --filter '@repo-prism/playground' devOpen the URL it prints. Pick a repository from the same dropdown Dispatch uses,
or pass ?root= on the URL.
What it is for
Trying Prism. Every screen the extension has, without installing into an editor.
Developing Prism. Spectrum and the extension share
@repo-prism/app-shell, so screen work lands in both. Spectrum has a
browser DevTools loop the extension webview lacks.
Differences from the extension
| Spectrum | Extension | |
|---|---|---|
| Open a file in an editor | No | Yes |
| Workspace | Dispatch-selected repo, ?root=, or environment | Editor folder |
| Reindex on save | Manual | Automatic |
