I sell WordPress stuff, and setting up demos was always a pain: a separate demo site to keep alive, spam signups, visitors breaking things for the next person.

So I built 'TryDemoWP'. Every visitor gets their own private copy of your site. It deletes itself when the timer runs out, so nobody can break it for anyone else.

The plugin, TryDemo Sandbox Publisher, means you don't have to export or upload anything:

1. Install it and paste a connect token

2. Click 'Push'

3. Get a demo link to share

What it does:

- Leaves out what a demo doesn't need: caches, backup folders, revisions, transients, spam comments

- Never exports `wp-config.php`, so your DB password and salts stay on your server

- Keeps going in the background even if you close the tab

- Shows live upload progress and an estimate of time left

- Adds an optional Buy Now bar and email capture to every demo, with click tracking

I'd love feedback, especially from theme and plugin sellers. What would make you switch from your current demo setup?
