Tools / performance and technical health
Check laboratory signals of mobile-loading problems.
We run local Lighthouse using a mobile profile and organise laboratory metrics with selected asset and technical signals. The result identifies areas for investigation; it is not a diagnosis of every user’s experience.
What we check
Technical signals in the context of a decision.
- FCP, LCP, CLS and selected Lighthouse metrics
- response time and initial rendering
- asset count and weight
- images, fonts and JavaScript
- selected cache and render-blocking signals
- third-party script impact
What you receive
A shorter route to the right action.
- 01laboratory mobile-profile score
- 02highest-impact delay signals
- 03evidence, impact and confidence
- 04priority for further measurement and optimisation
Honest test boundary
This is one laboratory Lighthouse run using a mobile profile. It does not measure real-user INP, represent every device or network condition, or prove the root cause without performance-trace analysis. Decisions should combine it with field data and critical user journeys.
„Great collaboration — reliable, fast and to the point!”

Efficient delivery
Define the scope of a deeper performance analysis.
Lighthouse surfaces signals in one mobile profile. A deeper analysis connects field data, performance traces and critical user journeys.
