Lifecheck is Swiftaw's spin on the "I'm not a robot" box. It watches how your cursor moves, throws a quick game if it's unsure, and hands your server a token. That's the whole thing.
The second it loads, Lifecheck records where your cursor goes. When you click, it runs three quick checks on that trail.
A cursor that barely twitched, or a click with no movement before it, reads as a script.
Real hands jitter the whole time. A straight, tweened path barely changes direction.
A click under 300ms after load is quicker than a person can actually react.
No blurry traffic lights. Small, tactile tasks a script can't fake but a person clears in seconds.
Real people usually sail straight through. No friction tax on the humans you want.
Every pass mints a token. Check it on your server with your secret key before you trust it.
The logic runs in a sandboxed frame on our domain. You embed a URL, not copyable code.
Cursor data lives a few seconds in the browser. No cookies, no profiles, nothing sold.
Grab a key, add the script once, drop a .lifecheck box in your form. The full guide is in the docs.
Lifecheck v1.2 is free to try and quick to wire up. Built by the people behind Fortized.
