OxiBrowser
Pure-Rust headless browser
You're building AI agents that need to browse the web. You don't need a full browser with GPU rendering, audio output, and extension support. You need something fast, small, and programmable. OxiBrowser is built for exactly that use case — a pure Rust browser engine with boa_engine for JS, html5ever for HTML, and BoringSSL for stealth TLS fingerprint emulation.

Single 24 MB binary
Pure Rust JS engine (boa), no V8, no Chromium. Run 100 instances without breaking a sweat.
~50 ms cold start
No Chromium overhead, no Node.js required. ~8 MB base memory footprint.
CDP-compatible
Puppeteer, Playwright, and any Chrome DevTools Protocol client works out of the box.
Secure by default
SSRF protection with CIDR blocking, robots.txt respect, no sandbox escape surface.
Agent-first CLI
--json output, describe for schema introspection, skill for agent prompts, session for multi-step automation.
Stealth TLS
BoringSSL C binding for stealth fingerprint emulation. Look like a real browser to anti-bot systems.
Install
cargo install oxibrowser In action
Real prompts, real output — the same interfaces humans and agents use.
