Add drawings, spreadsheets, interactive HTML tools, and PDF exports to your Lunaris workspace. This repository contains the official extension marketplace, extension source, and tools for building your own.
| Extension | What you can do |
|---|---|
| Excalidraw | Sketch ideas, map workflows, and collaborate on diagrams. |
| Exporter | Choose, order, and style workspace content for a PDF. |
| Mini Apps | Run a self-contained HTML tool inside your workspace. |
| Spreadsheet | Edit shared workbooks and exchange tabular data. Integration candidate; not published. |
| Northstar Pulse (Demo) | Learn the extension lifecycle through a dashboard with synthetic data. |
Each extension README covers use cases, features, usage, and the technology behind it.
Lunaris reads marketplace.json directly from this repository.
There is no registry website or GitHub API dependency.

Build and test the extension, create an artifact with registry/build-artifact.ts,
and commit it. Then run bun registry/update-marketplace.ts and commit the index
separately so descriptor URLs contain the artifact commit's full SHA.
Published versions are immutable by default. See the publishing guide for commands, verification, and the explicit replacement workflow.
Any public host can serve the same root JSON contract. GitHub users can point Lunaris
at https://github.com/owner/repository; Lunaris resolves its root marketplace.json.
Other hosts provide the complete HTTPS manifest URL. Descriptor URLs can be absolute or
relative to that URL. Descriptors and every executable asset are pinned by byte length
and SHA-256.
All manifest, descriptor, and asset responses must permit browser CORS, for example:
Access-Control-Allow-Origin: *
Content-Type: application/jsonSee template/README.md for one- and multi-extension layouts,
commit-pinned GitHub artifacts, and generic static hosting.
The extension sources and starter use Plugin SDK 0.10. The registry supports iframe sandbox protocols 6 and 7; protocol-7 builds require a compatible Lunaris host. The SDK emits runtime metadata during the build. Older builds without runtime metadata retain protocol 6.
