ElysionA collaborative whiteboard you can self-host

An open-source alternative to Mural. Draw together in realtime, share boards and rooms, run a timer and a dot voting. A pre-release.

Run it

Specifications

View on GitHub

Boards, rooms and templates

A board overview with rooms for teams, sharing with the roles owner, editor and viewer, built-in templates and your own, and PDF, PNG, SVG and .excalidraw export.

A realtime canvas

Excalidraw in the ariadne look, light and dark, with sticky notes, connectors and a minimap. Every change is merged by Yjs CRDTs, and you see everybody's cursor.

Facilitation

A shared timer with a countdown for everybody, and a dot voting with a ranked result when it ends, by the facilitator or when everybody has voted.

Identity you control

Login through Keycloak. The BFF, the realtime service and the business backend each check the token, and a viewer's changes are refused by the server.

Four images

Every merge to main publishes the frontend, BFF, realtime and business backend images to GHCR and creates a GitHub release, versioned by GitVersion.

A demo in one command

pnpm demo starts the whole stack with Docker, including its own Valkey, and three users to log in with.

Try it

With Docker, in one command (the images are built from a checkout; docs/self-hosting.md runs the published ones):

git clone https://github.com/GravionLabs/elysion.git && cd elysion
pnpm demo        # then open http://localhost and log in as dev, dev1 or dev2 (the password is the username)
