Would you like to know how to leave multiple subreddits at once? With Beleave, you simply mark the subreddits and click ‘Leave Communities”.

Hi, I needed to leave multiple subreddits but it was a hassle doing so manually one by one. So, I built ‘Beleave’ to help automate the task. It uses Reddit’s API to mass leave subreddits. It’s completely free. I didn’t even put ads in it.
