unInsta by DustFeather

unInsta lets you bulk unsend all your messages in any Instagram DM conversation, directly from your browser.

Open any DM thread on instagram.com, click the extension icon, and hit "Unsend All."
unInsta will find every message you've sent in that conversation and unsend them one by one, automatically.

HOW IT WORKS

1. Navigate to any DM conversation on instagram.com
2. Click the unInsta icon in your browser toolbar
3. Optionally set a date boundary to only unsend messages newer than a specific date
4. Click "Unsend All" and let it run

unInsta collects all your messages first, then unsends them with built-in rate limiting to stay within Instagram's limits.
You can see real-time progress with elapsed and remaining time estimates.
