What is Service Worker?

Getting Started

Our Getting Started guide gets you up, running and debugging a "Hello world" Service Worker in Chrome. If you are stuck the FAQ may have the answer you need.

Track Status

First cut of Service Worker in Chrome M40:

Is Service Worker Ready? tracks the implementation status of Service Worker at a fine-grained, feature-by-feature level in many popular browsers.

File Bugs

Go to and include "Service Worker" in the summary. You should get a response from an engineer in about one week.

If the browser crashed while you were doing Service Worker development, go to chrome://crashes and cut and paste the Crash ID into the bug report. This kind of bug report is very valuable to us. (If you do not see crashes in chrome://crashes it may be because you chose not to send usage statistics and crash reports to Google. You can change this option in chrome://settings .)

To give feedback about Service Worker that is not specific to Chromium, use W3C's public-webapps mailing list. Use the spec issue tracker to file bugs against the Service Worker spec.


For detailed questions about usage: ask us on StackOverflow with the "service-worker" tag.
