Bot Detection

Automatic filtering of bots, crawlers, and automated traffic.

How it works

Revlytics includes built-in bot detection that silently blocks all tracking for non-human visitors. No events are sent when a bot is detected.

Detection methods

The script checks for:

Method	What it detects
WebDriver flag	navigator.webdriver === true (Selenium, Puppeteer, Playwright)
Headless browsers	PhantomJS, Nightmare, headless Chrome
Known bot globals	window.callPhantom, window._phantom, window.__nightmare
User agent patterns	Common bot strings: bot, crawler, spider, headless, curl, wget, python, go-http-client
Missing user agent	Agents shorter than 5 characters or missing entirely
Document attributes	Automation-related attributes on document.documentElement

No configuration needed

Bot detection is always active and cannot be disabled. This ensures your analytics data is clean by default.

What happens

When a bot is detected, the script returns immediately — no events are sent, no replay is recorded, and no cookies are set. The detection is completely silent with no errors thrown.
