How Fugu is my browser? is an online testing tool for web developers that shows how well the current browser supports Project Fugu-related capabilities. Project Fugu is a cross-company collaboration aimed at giving web apps capabilities as close as possible to iOS, Android, or desktop apps, while preserving the Web’s core principles around security, privacy, and trust. In that sense, the site is more like a health check page for modern Web API capabilities in your browser.
Based on the captured page content, the tool identifies whether “my browser” is sufficiently “Fugu” and lists information such as Feature Name and Supported in Browser. The page also shows the usage share of certain capabilities during Chrome page loads, with data sourced from Chrome’s anonymous usage statistics across channels and platforms. It supports downloading test results by clicking Screenshot, and can also attach a screenshot after using Share, making it useful for developers discussing browser capability differences within teams, communities, or issues.
One thing to note is that the page explicitly states not all features are exposed on all platforms. For example, the Contact Picker API is currently only exposed on mobile, so achieving a 100% score is theoretically impossible. The official guidance also suggests treating the score as a fun competition rather than an absolutely scientific conclusion.
The captured content does not mention any paid plans, subscriptions, or commercial editions, so it can only be assumed that the page is likely free to use, but there is no formal pricing statement. There is also no information about an API, SDK, command-line tool, batch testing, or CI integration. Whether it is open source and whether self-hosting is available are also not disclosed in the captured content, so these should not be inferred.
Its main advantage is its very clear positioning: it quickly answers the question “how many Project Fugu capabilities does the current browser support?” The interface is also straightforward, and the screenshot and sharing features reduce the friction of distributing results. Its data is also tied to Chrome’s anonymous usage statistics, offering some ecosystem-level reference value.
The downside is that it is more of a lightweight testing page than a full compatibility database. For development decisions, you should still cross-check with MDN, Can I use, or Chrome Platform Status to confirm API details, permission models, platform limitations, and production readiness.
It is suitable for PWA developers, frontend engineers, browser capability researchers, and teams that need to evaluate the availability of modern Web APIs. The captured content does not provide information about access from mainland China, so actual network availability needs to be tested. If access is unstable, Can I use, MDN compatibility data, or Chrome Platform Status can be used as alternative references.
