Automate real browser profiles, not headless guesses
Headless browsers announce themselves through dozens of small differences. NexLogin profiles are full, headed browsers with persistent storage and a consistent fingerprint, and your scripts connect to them over the Chrome DevTools Protocol.
What goes wrong today
- Headless Chrome differs from a real browser in ways sites can see.
- Stealth plugins patch JavaScript and leave inconsistencies behind.
- Test sessions lose their logins every run.
Local REST API
Create, start and stop profiles from code. Each start returns a DevTools WebSocket URL.
Your framework, unchanged
Use connectOverCDP in Playwright, connect in Puppeteer, or debuggerAddress in Selenium.
Persistent sessions
Logins and cookies persist in the profile, so runs start already signed in.
How it works in NexLogin
Create profiles in the app or by API
Start a profile and get its CDP URL
Connect your script
Stop the profile; storage is saved
Frequently asked questions
Does automation change the fingerprint?
No. The fingerprint is set inside the browser, so a script and a person see the same values.
Is there a headless mode?
Profiles run headed by default because that is what real users run. A headless option for CI is planned.
