Performance Budgets with Lighthouse
Define and enforce performance budgets so size and metric limits are checked automatically, preventing regressions before they reach production.
What Is a Performance Budget?
A performance budget is a set of agreed limits, such as max JavaScript size or a minimum LCP, that the team commits not to exceed. It turns vague goals into enforceable thresholds.
Why Budgets Matter
Without budgets, performance erodes silently as features pile on. A budget makes regressions visible and blocking, shifting performance left into development.
