Performance budget — JSON
Lighthouse budget
The Lighthouse CI budget file I deploy on every B2B marketing site. Performance ≥ 90, A11y = 100, BP ≥ 95, SEO = 100. Mobile.
What’s in it
A lighthouserc.json file with budget assertions for Lighthouse CI. Configured for: Performance > 0.90, Accessibility = 1.00, Best Practices > 0.95, SEO = 1.00. LCP budget < 1500ms. CLS budget < 0.05. Total JS budget < 200KB.
How to use it
Drop into your repo root. Run lhci autorun in your CI pipeline. PRs that regress the budget fail the check. Configure to allow per-PR overrides for justified regressions.
