Blink Runtime-Enabled Features in Chromium

Blink runtime-enabled features serve as internal configuration flags that allow Chromium developers to manage new web platform capabilities without rebuilding the browser. These flags facilitate safely landing experimental code by keeping it disabled by default while enabling incremental testing, origin trials, and staged rollouts. Managed primarily through a central JSON5 configuration file, the system automatically generates the necessary C++ and JavaScript plumbing to gate logic across the engine. Beyond development, these features act as vital kill-switches that integrate with Chromium’s broader management systems, such as Finch field trials and enterprise policies. The framework ensures web compatibility remains intact by allowing features to mature through "test," "experimental," and "stable" phases before they are fully launched. Ultimately, this mechanism provides a disciplined approach to innovation, allowing the engine to evolve rapidly while maintaining a stable experience for end users.
