Edit this page, right now.

This is a working copy of TweakTags running entirely in your browser. There is no server and no sign up: the backend is a small script that keeps the content in memory, so nothing you do here leaves this tab, and a refresh puts everything back.

Click Sign in in the bar at the bottom right.
Use the demo account:
admin@example.com / password
There is a second account, editor@example.com / password, if you want to see what an editor sees.
Click Edit page. The editable spots pick up a dashed outline.
Click the heading or the paragraph below and type. Try the toolbar on the rich text.
Scroll to the three cards. Every line in them is its own tag, so a component is edited piece by piece rather than as one block.
Grab the bar anywhere that is not a button and drag it out of your way.
Click Save, then reload the page to see it come back from the store.

What just happened. The heading, the paragraph, and the banner image are ordinary HTML elements that each carry a data-tweaktags-* attribute, and so is every line of the three cards below them. TweakTags crawled the page, loaded the saved content, and made those elements editable for the signed in user. Everyone else sees the saved content and nothing else. That is the whole idea: you bolt it onto a site you already have, instead of rebuilding the site around a CMS.

Try managing users. Signed in as the admin, open Users in the bar. You can add somebody, change a role, reset a password, or delete a user. The rules are worth poking at, because the backend enforces them rather than the buttons hiding them:

Your own row has no Delete, and its role cannot be changed.
A superuser cannot be deleted. Change them to an editor first, then the Delete lights up. Removing an administrator is meant to be two decisions.
Click your email address in the bar to open Account and change your own email or password. Both ask for your current password first. Change the email and watch the address in the bar update straight away.
Sign in as editor@example.com and the Users panel is gone, but Account is still there. Managing people is superuser work; managing yourself is not.
