TRACIO is a next-generation device intelligence platform that identifies every visitor to your website or application with 99.5% accuracy. Unlike cookie-based tracking, TRACIO generates a persistent visitor identifier derived from over 300 browser signals that survives incognito mode, VPN usage, and cookie clearing.
Every visitor receives a unique visitorId that persists across sessions, browsers modes, and even after clearing cookies. The identification system collects 300+ distinct browser signals including canvas rendering, WebGL parameters, audio processing characteristics, font enumeration, and dozens more. These signals are processed server-side using a tiered MurmurHash3-128 hashing algorithm to produce stable, high-confidence identifiers.
import { Tracio } from "@tracio/sdk"
const tracio = Tracio.init({ publicKey: "5ca175fc..." })
const result = await tracio.getResult()console.log(result.visitorId) // "X7fh2Hg9LkMn3pQr5tBvQw3xZa9mK2pL4nR8dT6y"
if (result.bot.detected) { console.warn("bot, confidence:", result.bot.confidence)}Learn more about identification
A two-layer detection system combining client-side signals with server-side analysis to detect automation frameworks, headless browsers, and scripted attacks. TRACIO identifies Selenium, Puppeteer, Playwright, and headless Chrome, as well as AI browsing agents (Browser-Use, Claude Computer Use, and others) and antidetect browsers, which are scored rather than named. Good bots like Googlebot are verified via reverse DNS and allowlisted automatically.

Server-side enrichment signals provide deep context about every visitor. From VPN and proxy detection to device tampering analysis, smart signals give you the data needed to make real-time trust decisions without collecting any personally identifiable information.
| Signal Category | Signals Included |
|---|---|
| Network Intelligence | VPN, Proxy, Tor, Datacenter, IP Geolocation |
| Browser Analysis | Browser Tampering, Antidetect Browsers, Developer Tools, Privacy Settings |
| Bot & Automation | Automation frameworks, headless, AI agents, verified crawlers |
| Risk | Bot verdict (human/bot/uncertain), risk & suspect score |
Server-side IP analysis flags VPNs, proxies, Tor exit nodes, and datacenter origins, and resolves city-level geolocation and ASN — powered by commercial IP intelligence databases. These feed the aggregated risk and suspect scores.
