Summary
Obscura is an open-source headless browser engine written in Rust that runs JavaScript via V8, supports the Chrome DevTools Protocol, and serves as a Puppeteer and Playwright drop-in replacement.
It consumes 30 MB of memory in a 70 MB binary with built-in anti-detect, versus 200+ MB and 300+ MB for headless Chrome. The Apache-2.0 project captures screenshots, live screencasts, and PDF exports without requiring Chromium or Node.js.
