DebugBear Alternative: Free Website Speed Testing
Looking for a free DebugBear alternative? debugutils.dev gives you Lighthouse scores, Core Web Vitals, waterfall, filmstrip, and LCP analysis — no account required.
DebugBear is a solid web performance monitoring tool. It’s well-designed, has good CI/CD integration, and the Core Web Vitals tracking is useful. But it starts at $35/month and puts nearly everything behind a paywall. If you need a free alternative for one-off speed testing, here’s what to know.
What DebugBear Does Well
DebugBear focuses on continuous monitoring: you set up a schedule, it runs Lighthouse tests against your pages regularly, and alerts you to regressions. The trend charts and field data integration are genuinely useful for teams managing performance over time.
For teams who actively track Core Web Vitals as a KPI, the paid monitoring features are worth considering.
Where DebugBear Falls Short for Free Use
The free tier is limited to a handful of test runs with no scheduling and limited report depth. To access:
- Continuous monitoring
- CrUX field data
- Detailed historical trends
- CI/CD integration
- More than a few test runs
You need a paid plan.
