iQWEB – a diagnostic engine for website performance issues

I’m a solo developer from New Zealand and have been building a project called iQWEB over the past few months.

The idea came from a pattern I kept seeing when talking to web designers: tools like Lighthouse and PageSpeed produce a lot of metrics, but turning those signals into something meaningful for client conversations is difficult.

I started experimenting with a deterministic scoring model that analyses performance, structure and security signals and tries to identify the primary constraint affecting a site.

The output is a structured diagnostic report that highlights:

• the primary constraint affecting the site • the fixes most likely to produce the biggest improvement • explanations developers can use when discussing issues with clients

The goal isn’t to replace Lighthouse or PSI but to interpret those signals into something closer to a technical diagnosis.

Curious to hear whether developers think this kind of prioritisation model makes sense or if it misses the point.
