Public and Private Demo Links with Previews (Slack, X)
Share demos that actually preview and control who can access them.
What changed
Reliable Demo Share Link Routing
Fixed share demo link routing so /demo/share/:token is now served by the backend instead of the frontend SPA Shared demo links now return server-rendered HTML with metadata on the first request Eliminates cases where previews failed because bots were hitting the client-only app shell Share demo links now behave consistently across environments and platforms
Preview Demo Support for Slack and X
Shared demos now generate rich previews when pasted into Slack and X Open Graph and Twitter metadata is included directly in the initial HTML response Titles, descriptions, and preview images are now visible without requiring JavaScript Public links are optimized for distribution and visibility across platforms
Public and Private Demo Links
Added support for both public and private demo links Public demo links are open and optimized for sharing with previews Private demo links support invite-only access with approved-email verification Only invited viewers can access private demos, even if the link is forwarded Makes it easy to switch between broad sharing and controlled access
Preview Images for Shared Demos
Shared demo links now include preview images that display across Slack and X Replaced missing or inconsistent previews with a reliable image for every shared link Ensures images meet platform requirements (large, accessible, and publicly available) Lays the groundwork for demo-specific preview images in upcoming updates
Why it matters
Share demos that actually preview and control who can access them.
This release includes updates across Reliable Demo Share Link Routing, Preview Demo Support for Slack and X, Public and Private Demo Links, and Preview Images for Shared Demos.
