Sharing

Share a board as a live link that anyone can open in their browser. Comments come included.

Two ways to hand a board over

Click Share board in the top bar and the dialog offers both:

Export Board — download the board as a standalone HTML page with all media files and sub-boards bundled in a ZIP. No cloud, no setup, works offline. Free.
Live Link — publish the board to a URL anyone can open in a browser, with comments. Pro-only in the desktop app.

The same dialog imports an exported ZIP back into a board — see Importing a Shared Board, or Importing and Exporting Boards for the full round trip.

Where a live link is hosted

By default, live links go through GreenLight’s open storage — nothing to configure, and anyone with the link can view the board. The dialog says so under the two cards.

If you would rather host shares yourself, click Create own private storage in the same dialog. The app provisions everything in your free Cloudflare account — R2 bucket, D1 database, and the Worker — from a single API token. After that:

The URL is on your own Workers subdomain (or your custom domain).
The board HTML and media files live in your R2 bucket.
Comments live in your D1 database.
You own everything. You can take a board offline by deleting it from R2; you can export comments straight from D1.

Step-by-step: Cloudflare Account Setup.

For each shared board:

HTML page — a self-contained rendering of the board, hosted at https://<worker>/view/<share-id>.
Media files — every image and video, served from storage with CDN caching.
A download ZIP — the viewer page has a download button that hands visitors the board’s media as one archive.
Comments — viewers can leave threaded comments pinned to the canvas, without an account.

Cost

Open storage costs you nothing. On your own Cloudflare account, the free tier covers:

10 GB / month R2 storage with 1M Class A operations and 10M Class B.
100k / day Worker requests.
5 GB / month D1 storage with 5M reads, 100k writes.

For a few shared boards with moderate traffic, you stay inside the free tier. Heavy use (lots of large videos, viral boards) starts to incur Cloudflare’s metered pricing — the app cannot bill you, only Cloudflare can.

Free vs Pro

Live-link sharing in the desktop app is Pro-only. Export Board and Import board are free, and viewing a shared link needs nothing at all.
