Demonstrating your humanity with a CAPTCHA has never been more fun.

Frontend development firm Vercel has launched a Doom-themed CAPTCHA to highlight its AI website builder, as reported by [TechCrunch](https://techcrunch.com/2025/01/01/people-are-playing-a-new-doom-themed-captcha/). Rather than the typical “select all the images with traffic lights” task, this CAPTCHA dares users to take down three monsters from the legendary first-person shooter game, *Doom*.

The Doom CAPTCHA is labeled “for educational and entertainment purposes,” according to its site. So rest assured—you won’t have to rely on gaming expertise to access your bank account anytime soon. For now, you’ll still be faced with recognizing unclear images of stairs or motorcycles, likely failing a few times, as is customary with conventional CAPTCHAs.

Nevertheless, this Doom-themed CAPTCHA isn’t easy. The creators have heightened the intensity by ramping up the game speed and setting it to the “Nightmare” level. Despite the increased difficulty, the idea has sparked considerable [interest online](https://www.reddit.com/r/itrunsdoom/comments/1hr1o2a/doom_captcha_verify_youre_human_by_playing_doom/), with many keen to test their abilities and confirm they’re not bots.

If you’re ready to take on the challenge, you can see the Doom CAPTCHA for yourself at [https://doom-captcha.vercel.app/](https://doom-captcha.vercel.app/). On a desktop, navigate with the arrow keys and press the spacebar to fire. Best of luck, and enjoy hunting those monsters!
