Early Access Program
LRDefender identifies devices using GPU rendering, canvas, audio, and hardware signals — not cookies. We're looking for engineering and fraud teams who want to shape the next generation of device intelligence.
Platform Capabilities
What you can build with
Cross-Browser Device ID
Identify returning devices across Chrome, Firefox, Safari, and Brave using GPU-level signals that persist through incognito mode.
VPN & Proxy Detection
Detect VPNs, proxies, Tor exit nodes, and spoofed geolocations with multi-source IP reputation scoring.
Bot & AI Agent Detection
ML-powered behavioral analysis distinguishes real humans from headless browsers, automation frameworks, and AI agents.
90+ Hardware Signals
GPU renderer, WebGL pipelines, canvas fingerprint, audio context, font metrics, and dozens more — collected in under 40ms.
Real-Time Risk Scoring
Suspect scoring, velocity signals, replay attack detection, and federated threat intelligence — all computed in real time.
Self-Hosted Option
Deploy on your own infrastructure. No data leaves your network. Full control over retention, regions, and encryption keys.
Technology
How it works under the hood
LRDefender collects 90+ signals from your visitor's browser — including GPU rendering output, WebGL shader precision, canvas drawing differences, and audio processing characteristics — to build a cryptographic device fingerprint.
These hardware-level signals can't be cleared like cookies and persist across incognito sessions, browser switches, and VPN connections.
Signal Categories
GPU & WebGL Rendering
Shader precision, texture limits, and rendering output differences unique to each GPU
Canvas & Audio Fingerprints
Cryptographic hashes of rendered pixels and audio oscillator output
Hardware & Environment
CPU cores, memory, screen, timezone, language, and behavioral signals
Don't take our word for it
Try the live playground — it runs a real fingerprint on your browser and shows you all 90+ signals. No signup, no API key.
