Start with the foundations.
Fifteen automated checks of public HTML and response headers, explained in plain English. Get an initial indication of what deserves a closer look, without a signup.
This automated foundations check reads public HTML and response headers. It does not measure Core Web Vitals, visual design, accessibility conformance or application security. A high score is not a security certification.
What it checks
The same checks the studio ran on itself.
Every test here came out of auditing this studio’s own website — which failed several of them. The findings became the rebuild you are reading now.
Trust
HTTPS, security headers and selected response headers.
Clarity
Title, description, headline structure and image descriptions.
Mobile
Viewport handling, zoom blocking and fixed-width layout traps.
Speed
A single fetch sample, HTML size and compression.
Found
Link previews, structured data and canonical addresses.
What it cannot tell you
Automated checks find what is measurable. They cannot judge whether your message lands, whether the design earns trust in the first three seconds, or whether someone ready to buy can work out how to reach you. That judgement is the actual work — this tool highlights possible gaps for further review.
