v132 · Entropy Budget Tracker

Entropy Budget Tracker

sharedStorage.selectURL() is guarded by two per-page entropy budgets: a page-load budget (12 bits) and a site budget (30 bits across page loads). Chrome 132 saved queries mean a query is charged once, then free for the rest of the page load. This tracker lets you simulate query runs and see exactly when budgets are charged vs. free.
