OverpoweredJS Information

OverpoweredJS is the browser identity layer for the modern web. We replace brittle IP- and cookie-based controls with a durable, privacy-first browser fingerprint that survives VPNs, CGNAT, iCloud Private Relay, and incognito. With a single drop-in agent and API, teams detect automation and spoofing, score risk in real time, and enforce policy without adding friction. What we solve - Repeat signup & promo abuse without CAPTCHA or SMS - Click fraud and traffic laundering in ad flows - Anti-detect browsers, headless/automated tooling, and spoofed UAs - Geofencing/compliance that fails when IPs are masked - Dirty analytics from cookie clears and rotating addresses How it works - Persistent, pseudonymous browser IDs that remain stable across sessions, modes, and IP changes - High-entropy signal fusion (rendering, storage, timing, GPU/WebGL, WebRTC/network traits) to catch spoofing - Real-time botScore + risk signals for allow/deny, throttle, or step-up flows - Edge-first, first-party deployment to keep latency low and IDs durable - Simple integration: agent + REST API for Node, Cloudflare Workers, and modern front-end frameworks Privacy & compliance - Privacy by design: no need for PII to deliver accuracy - GDPR/CCPA-ready data handling Who uses us - SaaS and marketplaces protecting trials, credits, and promos - Fintech, ticketing, gaming, and media enforcing regional rules - Ad platforms and growth teams demanding clean attribution - Security teams blocking bots before they hit core endpoints Outcome One user, one profile—even when the IP changes. Stop chasing IPs. Start recognizing browsers. Learn more: https://overpoweredjs.com
