Share the prototype, not the zip file.

Drop an HTML file or a zipped prototype and get a link your team can open in seconds. Revisions keep the same link, and everything cleans itself up after 72 hours.

Made for the messy middle of design work

Instant share links

One upload, one short link. Send it to a teammate, a client or the whole studio.

Gone in 72 hours

Links expire on their own, so old drafts never linger in someone's inbox.

Versions and rollback

Publish revisions behind the same link and step back to any earlier version.

Sandboxed by default

Every prototype runs in a locked-down sandbox, away from your account and your team's.

How it works

1
Drop a file
An HTML page or a zip with index.html at the top. Drag it in, or publish from a script.
2
Get a link
The link works right away. Add a viewing password if it shouldn't travel.
3
Share it
Send it to anyone, or share it with a teammate on Mock so it shows up in their portal.

Mock is invite-only

To get in, ask your admin to add your GitHub username. Then sign in with that GitHub account.
