What is it?

Ignis is a compatibility layer that supplies browser-compatible implementations of the Electron APIs Obsidian relies on, so the Obsidian interface can run in a standard web browser instead of through a remote desktop session. Your vault stays on the server, and the Docker image downloads Obsidian from its official source at first start rather than bundling it.

It supports the core Obsidian editor, canvas, bases, themes and CSS snippets, plus most community plugins built on the plugin API. Plugins that need Node native modules or child_process do not load. Multi-vault management, file upload and download, live sync between browser tabs over WebSocket, and a mobile layout are included.

The project is in active development and has no built-in authentication, so it should be placed behind an authentication layer and served over HTTPS before being exposed to other machines.
