Migrating from the Chrome App?

The original Web Server for Chrome was a Chrome App used by 200,000+ people. Google discontinued Chrome Apps, so its original author is carrying the familiar workflow forward as 200 OK Web Server.

The Chrome extension launches the desktop app and controls the ChromeOS Linux version; it does not serve files itself.
ChromeOS users can choose Android through Google Play or the Linux version on compatible devices. Compare ChromeOS options.
Feature availability differs by platform. Feature parity is a direction, not a claim that every legacy option is already present.

The original Chrome App source code is preserved in the legacy branch.
