Three steps. Five minutes.

From zero to bot detection in less time than making coffee.

01

Add one line of code

<script src="https://device.ai/v1/detect.js"></script>

Drop our 4KB script into any page. Works with every framework.

02

Every visitor gets scored

{
  "score": 0.94,
  "bot": false,
  "risk": "low"
}

50+ device signals analyzed in under 100ms.

03

Block bots, allow humans

if (result.score < 0.3) {
  return res.status(403).json({ error: "bot_detected" })
}

Set your threshold. We handle the rest.

What we see

We see 278+ signals per session

Hardware, rendering, automation tells, motor behavior and network context, cross-checked against each other. Bots can fake one layer. They rarely fake all of them consistently.
