Best Captcha Discord Bots

A captcha bot puts a gate between joining and posting: the new member solves a challenge, then receives a verified role that opens the rest of your channels. It filters out most automated raid accounts, but it also adds friction for real people, so the challenge type matters. A single button click, an image code and an external web page are very different asks.

Set it up before you need it. You need a locked-down @everyone permission set and a verified role that actually unlocks something, because the bot only hands out the role and will not fix your channel permissions for you. Check whether failures are logged, whether there is a timeout kick, and whether alt detection is premium.
