Chrome OS Updates

A modern, fast, and accessible website for tracking Chrome OS version updates, recovery images, and device information.

Live Site: https://cros.tech

About

Chrome OS Updates provides up-to-date information about Chrome OS versions across all devices and boards, including:

• Current stable, beta, dev, and canary versions for every device
• Recovery image downloads for all channels and versions
• Device specifications including architecture, kernel versions, and capabilities
• Chrome OS Flex update information
• Historical version data

This site was orignally built to provide a more user-friendly and performant alternative to the now-defunct cros-updates-serving appspot app.

Data Sources

All Chrome OS version and device data is sourced directly from Google's official APIs and community-maintained repositories:

• Version Data: Chromium Dashboard API
• Recovery Images: Google Chrome OS Recovery
• Chrome OS Flex: Flex Recovery Data
• Device Metadata: ChromeOS Update Directory - Enhanced device capabilities, kernel versions, architecture, and hardware information. (Thanks jay0lee!)

Data is automatically updated every 15 minutes via GitHub Actions (see .github/workflows/scrape.yml).
