Is this Threads character counter free?

Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.

What happens if a Threads post goes over the limit?

Threads crops or refuses it. The counter marks the exact tail that would be lost, so you can cut the right words instead of guessing.
