Block bot signups without making people solve puzzles.
Attrelix looks at the inbox, the network, the browser and the accounts a signup is linked to, and returns a decision with reasons in milliseconds.
One script tag and one server call. No card to start.
Why fake signups hurt
Bot signups fill your database with accounts that never convert, burn free usage, send spam through your product and skew every activation metric you track.
CAPTCHAs slow real people down and are solved cheaply by services. Checking the signup itself catches what the puzzle misses.
What gives a fake signup away
Automation
WebDriver, headless browsers and DevTools-protocol control, plus browsers with zero-size windows, software rendering or contradictory fingerprints.
Missing or replayed tokens
A signup that skipped your page's script, or reused a token, never ran in a real browser session. Both add risk.
Bursts
Many signups from one device, address or subnet in a short window, the shape a script leaves behind.
Questions
Does it replace a CAPTCHA?
It can. Many teams remove the CAPTCHA and show one only when Attrelix returns review.
Does the script slow down my page?
The agent is a small file loaded with defer. It collects signals in the background and does not block rendering.
Can bots just skip the script?
Then the check has no valid token, and a missing token adds risk points you control in settings.
What does it cost?
1,000 checks a month are free with no card. Paid plans start at $29 a month for 10,000 checks.
Other use cases
Stop paying for someone else's script.
1,000 checks a month free. No card.
