BotD is a free, MIT-licensed browser library that detects automation tools and frameworks such as Puppeteer, Selenium, Playwright, and headless Chrome. It runs entirely client-side with no server required, making it easy to add basic bot detection to any web app.
Use cases
- detect bots visiting my website
- block headless chrome traffic
- detect puppeteer and selenium automation
- client-side bot detection without a server
- identify automated browser sessions
- detect playwright headless browsers
- add bot detection to a web app
When to choose
- you need free, permissively licensed (MIT) bot detection
- you want detection to run 100% in the browser with no backend
- you need to catch common automation tools like Puppeteer, Selenium, or Playwright
- you want a lightweight npm or CDN drop-in for a web app
When to avoid
- you need advanced, continuously updated bot detection against sophisticated evasion - consider a commercial API like Fingerprint Pro
- you need server-side or backend bot detection
- you expect frequent new features - the project is in stability-only maintenance mode
