korvus-browser

pip install korvus-browser gives you the korvus command: a browser engine for AI agents and automation, written from scratch in Rust, that Playwright, Puppeteer and any Chrome DevTools Protocol client drive as they drive Chrome.

pip install korvus-browser
korvus serve          # a DevTools endpoint on 127.0.0.1:9222

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp("http://127.0.0.1:9222")
    page = browser.new_context().new_page()
    page.goto("https://example.com")
    print(page.title())

This package is a launcher: the first korvus downloads the engine release of the same version from GitHub, checks it against the release's SHA256SUMS, keeps it under ~/.cache/korvus-browser/ and runs it. Linux (x86-64), macOS (Apple silicon) and Windows (x86-64).

Updates

korvus update upgrades this package with pip (pip install --upgrade korvus-browser), and the next korvus runs the new engine. Run in a terminal, korvus also checks for a newer release at most once a day and asks Update now? [Y/n]; KORVUS_UPDATE=off (or reminder, or auto) changes that. It never checks or asks outside a terminal, so scripts and CI are untouched.

License
