A Rust dev just killed Headless Chrome.
It's called Obscura. The open-source headless browser purpose-built for AI agents and scrapers at scale.
Chrome vs Obscura:
- Memory: 200MB+ → 30MB
- Binary: 300MB+ → 70MB
- Page load: 500ms → 85ms
- Startup: 2s → Instant
- Anti-detect: None → Built-in
Single binary. No Node, no Chrome, no dependencies.
Stealth mode is brutal:
→ Per-session fingerprint randomization (GPU, canvas, audio, battery)
→ 3,520 tracker domains blocked by default
→ navigator.webdriver masked to match real Chrome
→ Native function masking so detectors can't sniff it out
Drop-in replacement for Puppeteer and Playwright over CDP. Zero code changes.
If you run agents or serious scraping at scale, this repo prints money.
100% Opensource.
