OneBuddy is designed to be lightweight and uses Chrome's efficient Manifest V3 architecture.
Manifest V3 uses service workers instead of persistent background pages, meaning OneBuddy's background processes only run when needed rather than consuming resources continuously.
In practice, OneBuddy actually reduces total resource usage for users who replace multiple single-purpose extensions. Running one extension instead of 8-10 separate ones decreases overall memory consumption and CPU usage.
Ad and tracker blocking further improve performance by preventing resource-heavy advertising scripts and tracking pixels from loading on web pages.
If you experience any performance issues, check chrome://extensions/ to see memory usage for each installed extension. OneBuddy is typically among the lightest despite offering the most features.
