At Google I/O 2025, we unveiled new features to supercharge your productivity and to empower you to build a more powerful, seamless, and modern web.
Here are 10 key innovations that put cutting-edge capabilities directly in your hands and are sure to inspire your next project.
1. Carousels are easier than ever to build with a few lines of CSS and HTML
Build beautiful carousels with CSS that are interactive at first paint. Chrome 135 introduced new CSS primitives—styleable fragmentation, scroll marker elements, and scroll buttons—simplifying carousel creation without JavaScript. Use familiar CSS concepts to create rich, interactive, smooth, and more accessible carousels, in a fraction of the time.
2. Declarative Popovers: Introducing the new Interest Invoker API
The experimental Interest Invoker API is available as an
origin trial.
With this feature, you can declaratively toggle popovers when visitor interest
is active for a small duration. Goodbye unstylable
[title] attribute; hello
[interesttarget]! Combine it with the
Anchor Positioning API and
Popover API
to create
rich, responsive, and interactive UI elements like tooltips or hover cards,
without JavaScript. The possibilities are endless with modern CSS!
3. Several built-in AI APIs using leading models like Gemini Nano are available, now featuring multimodal capabilities in the Prompt API
Our built-in AI journey continues, bringing you enhanced privacy, reduced latency, and lowered cost, along with access to high-quality, AI-created output. Built-in AI uses expert models and Gemini Nano, Google's most efficient model, for on-device tasks. From Chrome 138, the Summarizer API, Language Detector API, Translator API, and the Prompt API for Chrome Extensions are available in Stable. In addition, the Writer API and Rewriter API are available in origin trials.
The new Proofreader API, along with the Prompt API with multimodal capabilities, are available in Chrome Canary.

4. Client-side AI extends with Firebase and Gemini Developer API to provide a hybrid AI solution
Our collaboration with Firebase and Gemini Developer API means you can now build AI-driven web experiences on mobile and desktop. These applications use client-side AI when possible and seamlessly scale to server-side AI to reach all devices and browsers. Starting today, Firebase AI Logic provides seamless access to Chrome's built-in Prompt API backed by Gemini Nano and similar smaller models on the server side using the Gemini Developer API.
5. AI assistance in Chrome DevTools supports your debugging workflow across styling, performance, and more
With AI assistance, you can chat with Gemini to help you debug styling errors in the Elements panel, resolve performance problems in the Performance panel, identify network issues in the Network panel, and locate source files in the Sources panel. Plus, AI assistance can now apply its styling-related changes directly to your source code in the Elements panel.
6. Real-user data, Lighthouse Insights, and AI features in the Chrome DevTools Performance panel helps you understand and fix performance issues
With the reimagined Performance panel, you can now access local and real-user Core Web Vitals data and ask Gemini to help you understand and fix performance issues. The Insights sidebar brings Lighthouse insights into your traces helping you debug faster—all without having to leave your workflow or disrupt your productivity.
7. Baseline features availability is now in your familiar tools: VS Code, ESLint, and more
Achieve greater accuracy and confidence in your web development workflow with Baseline integration. Within your familiar web development tools, you will gain clear visibility into the availability of web features across major browsers:
- IDEs: VSCode now displays the Baseline status of features right as you build, with support coming soon to WebStorm by JetBrains and VS Code-based IDEs including Firebase Studio, Windsurf, GitHub Codespaces, and more.
- Linters: CSS and HTML linters can proactively warn you when you're using a feature that is newer than your Baseline target. Baseline is supported in ESLint for CSS, HTML ESLint, and Stylelint.
- Analytics: RUMvision combines Baseline data with real user metrics, letting you strategically select the optimal Baseline version for your audience. Google Analytics users can upload their data to the Google Analytics Baseline Checker to get Baseline recommendations.
- Compilers: use browserslist-config-baseline to plug your Baseline targets into your code compilation tools like Babel and PostCSS so that you can use modern features in your source code, and compile them down in your production builds.
8. Gain a complete view of web feature support with Web Platform Dashboard
Last year we announced the Web Platform Dashboard, a way to explore the web-features data that maps the entire web platform as a set of features. With the web-features dataset now 100% mapped, for the first time ever, you can see the Baseline status of every feature on every browser—from AVIF to View Transitions—including their availability and adoption. Stay informed and build with confidence!
9. Developer trial for a streamlined sign-in experience with Credential Manager
We recognize the friction that multiple authentication methods, including passwords, identity federation, and passkeys can cause for users of your sites. Our goal is to bring a unified and effortless sign-in experience for users, and so we're bringing the intuitive experience of Android's Credential Manager to Chrome. Soon, when users click sign in Chrome will surface credentials which are available for this site, such as passkeys and passwords from Google Password Manager, making sign in seamless. We plan to add identity federation to this experience too. The Credential Manager for the web is now in developer trial; stay tuned for more updates later this year.
10. Iterate on Chrome Extensions faster with the ability to cancel submission review
Submitting your Chrome Extension should feel seamless, worry-free, and exciting! However, we know that one area of friction was being unable to quickly fix a mistake in a pending submission. Earlier this year, we introduced the ability to cancel a pending submission, which builds on the ability to roll back a previously published version—all with the goal of letting you make changes and resubmit quickly.
