What It Is ​

Nstbrowser is an antidetect browser platform built for web scraping, automation, and multi-account management. It issues each browser profile a unique, authentic-looking fingerprint (canvas, WebGL, navigator, fonts, timezone) so that target sites cannot link sessions or detect automation.

It ships both a free desktop client (Windows) and a Docker-based cloud deployment. You drive it programmatically via a local REST/WebSocket API on localhost:8848, a Node.js SDK (nstbrowser-sdk-node), or a Python SDK (nstbrowser). Playwright, Puppeteer, and Selenium all connect through the standard Chrome DevTools Protocol (CDP) endpoint it exposes.

Key Features ​

  • Authentic browser fingerprints to prevent tracking and cross-session linking
  • Multi-account management: thousands of profiles with isolated cookies, storage, and fingerprints
  • Built-in proxy support with deep per-profile integration ($0.40/GB for managed proxies)
  • Cloudflare bypass and CAPTCHA solving
  • AI agent mode for autonomous task execution
  • Deployment options: local desktop client, Docker container, or dedicated cloud server
  • SDK support for Node.js and Python, plus raw HTTP/WebSocket API
  • CDP-compatible: connect any Playwright, Puppeteer, or Selenium script without code changes

Free vs Paid ​

Safety and ToS Notes ​

  • Users must agree to Nstbrowser's Terms and Conditions, Privacy Policy, and Cookies Policy upon registration.
  • Nstbrowser provides the infrastructure; you remain solely responsible for complying with the terms of service of any site you access through it.
  • Do not use Nstbrowser to bypass access controls where prohibited by the target site's ToS or applicable law.
  • Antidetect browsers are ToS-sensitive: some platforms (ad networks, marketplaces) explicitly prohibit multi-account use. Verify before automating.
