This mode ignores the soft process limit and behaves just like a process-per-site policy for all sites, with an additional restriction that a process may only be reused while the number of main frames in that process stays below a threshold. | ❌ |
| ServiceWorkerAutoPreload | Enables auto preloading for fetch requests before invoking the fetch handler in ServiceWorker. The fetch request inside the fetch handler is resolved with this preload response. If the fetch handler result is fallback, uses this preload request as a fallback network request. Unlike navigation preload, this preloading is applied to subresources. Also, it doesn't require a developer opt-in. crbug.com/1472634 for more details. | ❌ |
| ServiceWorkerStaticRouter | Enables ServiceWorker static routing API. https://github.com/WICG/service-worker-static-routing-api | ✅ |
| ServiceWorkerStaticRouterRaceNetworkRequestPerformanceImprovement | crbug.com/374606637: When this is enabled, race-network-and-fetch-hander will prioritize the response processing for the network request over the processing for the fetch handler. | ❌ |
| RunVideoCaptureServiceInBrowserProcess | Run video capture service in the Browser process as opposed to a dedicated utility process. Camera requests from Lacros are forwarded to Ash via a Mojo connection established through cros-api. Since cros-api isn't available in utility processes, Lacros's video capture service has to run within the browser process. | ❌ |
| SchedQoSOnResourcedForChrome | Update scheduler settings using resourced on ChromeOS. | ❌ |
| SecurePaymentConfirmationBrowser | Browser-side feature flag for Secure Payment Confirmation (SPC) that also controls the render side feature state. SPC is not currently available on Linux or ChromeOS, as it requires platform authenticator support. | ❌ |
| SecurePaymentConfirmationDebug | Used to control whether to remove the restriction that PaymentCredential in WebAuthn and secure payment confirmation method in PaymentRequest API must use a user verifying platform authenticator. When enabled, this allows using such devices as UbiKey on Linux, which can make development easier. | ❌ |
| ServiceWorkerPaymentApps | Service worker based payment apps as defined by w3c here: https://w3c.github.io/webpayments-payment-apps-api/ TODO(rouslan): Remove this. | ✅ |

| SiteIsolationForCrossOriginOpenerPolicy | Controls whether to isolate sites of documents that specify an eligible Cross-Origin-Opener-Policy header. Note that this is only intended to be used on Android, which does not use strict site isolation. See https://crbug.com/1018656. | ❌ |
| DisableProcessReuse | When enabled, OOPIFs will not try to reuse compatible processes from unrelated tabs. | ❌ |
| SpareRendererForSitePerProcess | Controls whether SpareRenderProcessHostManager tries to always have a warm spare renderer process around for the most recently requested BrowserContext. This feature is only consulted in site-per-process mode. | ✅ |
| StrictOriginIsolation | Controls whether site isolation should use origins instead of scheme and eTLD+1. | ❌ |
| SubframeProcessReuseThresholds | Controls whether subframe process reuse should be restricted according to resource usage policies. Namely, a process that is already consuming too much memory is not attempted to be reused. | ❌ |
| SuppressDifferentOriginSubframeJSDialogs | Disallows window.{alert, prompt, confirm} if triggered inside a subframe that
is not same origin with the main frame. | ❌ |
| SyntheticPointerActions | Dispatch touch events to "SyntheticGestureController" for events from Devtool Protocol Input.dispatchTouchEvent to simulate touch events close to real OS events. | ❌ |
| TouchDragAndContextMenu | This feature allows touch dragging and a context menu to occur simultaneously, with the assumption that the menu is non-modal. Without this feature, a long-press touch gesture can start either a drag or a context-menu in Blink, not both (more precisely, a context menu is shown only if a drag cannot be started). | ❌ |
| UnrestrictedSharedArrayBuffer | This feature is for a reverse Origin Trial, enabling SharedArrayBuffer for sites as they migrate towards requiring cross-origin isolation for these features. TODO(bbudge): Remove when the deprecation is complete. https://developer.chrome.com/origintrials/#/view_trial/303992974847508481 https://crbug.com/1144104 | ❌ |
| UseBrowserCalculatedOrigin | Enable using browser-calculated origins on navigations, instead of renderer-calculated ones. | ❌ |
| UserActivationSameOriginVisibility | Allows user activation propagation to all frames having the same origin as the activation notifier frame. This is an intermediate measure before we have an iframe attribute to declaratively allow user activation propagation to subframes. | ✅ |
| VerifyDidCommitParams | Enables comparing browser and renderer's DidCommitProvisionalLoadParams in RenderFrameHostImpl::VerifyThatBrowserAndRendererCalculatedDidCommitParamsMatch. | ✅ |
| V8VmFuture | Enables future V8 VM features | ❌ |

| WebBluetoothNewPermissionsBackend | Controls whether Web Bluetooth should use the new permissions backend. The new permissions backend uses ObjectPermissionContextBase, which is used by other device APIs, such as WebUSB. When enabled, WebBluetoothWatchAdvertisements and WebBluetoothGetDevices blink features are also enabled. | ❌ |
| WebOtpBackendAuto | Controls which backend is used to retrieve OTP on Android. When disabled we use User Consent API. | ❌ |
| WebPayments | The JavaScript API for payments on the web. | ✅ |
