headless-detection

Agent Skills for browser fingerprint testing: run liarjs from Claude Code, Codex, Cursor or Copilot to score a browser against itself - 40 consistency checks over canvas, WebGL, WebGPU, audio, fonts and WebRTC, cross-checked against the TLS/HTTP layer. Playwright and Puppeteer harness QA, CI regression gates, headless detection triage.

Privacy-first browser attestation framework for anti-bot and anti-AI scraping. Stateless, cryptographic, and Unix-native. Uses Ed25519 heartbeat chains, WASM attestation, and behavioral continuity validation without tracking users, storing IPs, or collecting telemetry.

Detect bots, verify humans.

Browser tamper detection for hostile environments. Detects and blocks DevTools, automation drivers, extension injection and environment spoofing. Surfaces findings as structured risk signals, not just boolean flags.

Deep in-browser detector for Chrome DevTools Protocol traces and browser-automation artifacts. 31 probes: CDP side-channels, input-event forensics, behavioural biometrics, framework artifacts, cross-realm consistency, anti-detect tamper forensics.

Client-side HTML mutation engine — rewrites the live DOM every load so scrapers, headless browsers, and AI vision models see a hostile, ever-changing document, with zero change for real users.
