Humans get on. Bots miss the train.
Captchoo stops bots without making people squint at traffic lights. Invisible for most visitors, a two-second slide for the rest, and no tracking cookies.
Why Captchoo
Security your visitors won't even notice.
Most people never see Captchoo at all. Their browser quietly proves it is real, and they carry on with what they came to do.
Private by design
No tracking cookies, no ad profiles, nothing sold. Captchoo checks for bots, not people.
A slide, not a puzzle
When a visitor does need a check, it is one easy slide with keyboard and screen reader support.
Feather light
A small script that loads after your page, so it never slows down your sign up.
See what you stopped
A simple dashboard of real visitors, blocked bots and where they came from.
Developers
Two lines in. Bots out.
Drop in the script, put the widget in your form, and check the token on your server. Works with any stack: plain HTML, React, Vue, WordPress, Laravel, Rails or Node.
- Drop-in replacement for the checkbox you use today
- One verify call from your server
- Test keys for local development

Questions
All aboard?
What is Captchoo?
Bot protection for websites: sign up forms, logins, checkouts and comments. It stops automated abuse without making real people solve image puzzles.
How does it tell humans from bots?
Most visitors pass invisibly: their browser solves a small math puzzle that costs a person nothing but adds up fast for bots sending thousands of requests. When more proof is needed, Captchoo shows one quick slide.
Does it track my visitors?
No. Captchoo sets no tracking cookies, builds no ad profiles and sells nothing. It only answers one question: human or bot?
Is it accessible?
Yes. The slide works with a mouse, a finger or the keyboard, and screen readers announce every step. No one is ever asked to identify pictures.
