[Project Fugu](https://developer.chrome.com/docs/capabilities/fugu-showcase) is a cross-company effort that lets web apps do anything mobile apps can.
Debug the powerful Project Fugu APIs with Chrome DevTools.

With DevTools you can:

- Emulate [sensors](https://developer.chrome.com/docs/devtools/sensors.md.txt) such as:
  - Idle detector states.
  - Device orientation.
  - Geolocation overrides.
- [Test URL protocol handlers](https://developer.chrome.com/docs/devtools/progressive-web-apps.md.txt#test-protocol-handler) for Progressive Web Apps.
- Test tokens for [origin trials](https://developer.chrome.com/docs/web-platform/origin-trials.md.txt).
- Explore the Origin Private File System (OPFS) of a web application with a [DevTools extension](https://chrome.google.com/webstore/detail/opfs-explorer/acndjpgkpaclldomagafnognkcgjignd).
