Muffle vs Circleboom

Both tell you who unfollowed you, and both do it well. They are built on opposite foundations, which is what decides whether either is right for you.

They are built for different jobs

Circleboom is a management suite. It authenticates as you against X's API and runs the work on its servers, which is what lets it schedule posts, write with AI, bulk delete old tweets and work from your phone. If managing accounts is part of your job, that is the shape of tool you want, and Muffle does not compete for it.

Muffle is an extension for the account you read every day. It reads the pages your own browser already loaded, so there is no account to connect and nothing on a server. That means no API bill to pass on, no follower ceiling, and no third party holding your follower history.

Where Muffle wins

Nothing to authorise. Circleboom needs an app connected to your X account. Muffle never asks, so there is no token to leak and nothing to revoke.
No follower ceiling. Their unfollower tracking stops at 25,000 followers. Muffle reads whatever your browser loads.
A year costs less than two months. $29 a year against $23.99 a month for the plan that includes unfollower tracking.
Four more things come with it. Turning off the feed, filtering by bio, bookmark search and the one-way follows list.

Where Circleboom wins

It works on your phone. Muffle is desktop Chromium only.
Scheduling, AI writing and analytics. Muffle has none of it and is not planning to.
Bulk deleting your own posts and likes. Muffle never deletes anything.
Your history survives a dead laptop, because it lives on their servers.

The trade, stated plainly

With Muffle, if your laptop dies, your follower history dies with it. With Circleboom, if pricing changes or they shut down, your access goes instead. Both are real. Pick the failure you would rather own.

Which to pick

Circleboom if managing X is part of your job: scheduling, bulk deletion, analytics, and access from your phone.
Muffle if X is somewhere you read and post, you want to know who unfollowed you without connecting your account to anybody, and you are on a desktop.
