Web Platform
Read the documentation for Web Platform APIs, some of which are experimental in Chrome. For example, origin and developer trials, or features only found in Canary.
What are Chrome release channels?
Learn how Chrome uses Canary, Dev, Beta, and Stable release channels to test new features, and roll out updates.
What are Chrome flags?
Activate additional debugging tools, or try out new or experimental features.
What are Chrome Variations?
Test new features or changes to the Chrome browser or Chrome OS which runs on Chromebooks.
Shipped APIs
Page Lifecycle API
The Page Lifecycle API provides lifecycle hooks so your pages can safely handle these browser interventions without affecting the user experience.
Early Hints
Early Hints is an HTTP status code (103 Early Hints) used to send a preliminary HTTP response ahead of a final response.
Picture-in-Picture for any Element
Display arbitrary HTML content in an always-on-top window.
Better screen sharing with Conditional Focus
Conditionally focus a tab or window when screen sharing on the web.
Privacy-preserving screen sharing controls
Guide the user away from oversharing thanks to privacy-preserving screen sharing controls on the web.
Better tab sharing with Capture Handle
The web platform now ships with Capture Handle, a mechanism that allows a capturing web app to ergonomically and confidently identify the captured web app, if the captured web app has opted-in.
Recognize your users' handwriting
The Handwriting Recognition API allows web applications to use advanced handwriting recognition services to recognize text from handwritten input in real time.
Navigation API
Discover modern client-side routing with the Navigation API, which adds improved functionality to build single-page applications.
Better tab sharing with Region Capture
The web platform now ships with Region Capture, a performant and robust way for cropping a video track.
Full control with the VirtualKeyboard API
Manage yourself the browser deals with content occlusion when a touch device's virtual keyboard appears.
Smooth and simple transitions with the View Transition API
The View Transition API lets you create seamless visual transitions between different views on your website.
Prefetch and prerender pages with the Speculation Rules API
Use the Speculation Rules API to achieve near-instant page navigations
Long Animation Frames (LoAF)
Use the Long Animation Frames API to identify slow animation frames which are likely to affect the Interaction to Next Paint (INP) Core Web Vital metric which measures responsiveness.
Back/forward cache notRestoredReasons API
Report information on whether a page was blocked from using the back/forward cache on navigation.
Get started with origin trials
Test a new or experimental web platform feature.
Third-party origin trials
Providers of embedded content can test new or experimental web platform features.
Troubleshoot origin trials
Address common problems with Chrome trial tokens in meta tags, headers, and scripts.
Origin trials
Origin trials allow developers to try out new features and give feedback.
Scroll and zoom a captured tab
The Captured Surface Control API lets web apps scroll and zoom captured tabs.
Capture a video stream from any element
The Element Capture API is a performant and robust way for transforming a capture of the current tab into a capture of a DOM subtree.
Launch Handler API
Control how your app is launched, for example, whether it uses an existing or a new window and whether the chosen window is navigated to the launch URL.
Measure soft navigations
Experimenting with JavaScript-driven same-document navigations that use the history API or the new Navigation API, triggered by a user gesture and modifies the DOM, modifying the previous content, as well as the URL displayed to the user.
Compute Pressure API
Allow your implementation to use the right underlying hardware metrics to ensure that users can take advantage of all the processing power available to them
Deprecating
These features were part of the web platform but are now in the process of being deprecated and removed.
Deprecating the unload handler
The unload event will be gradually deprecated starting from Chrome 117. Learn what this means and how sites and enterprises can prepare for this
No longer pursuing
These features are no longer supported nor in experiment.
Declarative Link Capturing

Storage Foundation API
Gain direct access to stored data through buffers and offsets.
Notification triggers
Schedule local notifications that don't require a network connection
