Our story

Why PerfLeaf exists

In today's digital world, every millisecond matters. Slow websites frustrate users, hurt conversions, and waste energy. Yet many teams struggle with fragmented tools, incomplete data, and unclear priorities.

We built PerfLeaf to solve this with one platform for Core Web Vitals monitoring, accessibility auditing, security assessment, carbon footprint tracking, and clear recommendations that tell you what to fix first.

A full audit is a detailed snapshot, but websites can change between scans. Leaf Watch checks your homepage and robots.txt every day, compares the result with the last healthy baseline, and alerts you when availability, search visibility, metadata, or response behaviour changes.

How it works

Insight in three simple steps

01

Connect your site

Add a URL and we handle the rest — no code, tags or scripts required.

02

We scan and keep watch

Full-site audits measure every page, while Leaf Watch checks critical homepage signals daily.

03

Get a plan of action

Receive a prioritised list of fixes with AI-powered recommendations and clear impact.
