Web studio with its own testing software
Websites that are fast, get found and work for everyone.
We build new websites, fix barriers and bugs in existing ones and look after them afterwards. Every job is backed by a measurement before and after. Fixed price after a written request, no meeting needed.
Eight services: new websites and shops, fixing what is broken, getting faster and easier to find, documents, ongoing care.

Before and after, measured
Three example pages, deliberately built with typical faults and then fixed. Both versions are public, so you can check every number yourself.
Loading speed
Google PageSpeed, mobile

Oversized images, a blocking script in the head and layout jumps removed. Largest element after 2.1 instead of 6.8 seconds.

Five causes: invisible focus, unlabelled fields, a pay button made of a div, low contrast, missing text alternatives. Automated tests do not cover every criterion.

How we work
Everything in writing. You never need to book a meeting, and every agreement can be read again later.
Request
You send the address and what you need through the form. A few sentences are enough.
Measurement and fixed price
We measure the current state and send an offer: what we do, by when, at what price.
Implementation
In the real code of your website, in your system. No add-on script that merely hides faults.
Proof
The same measurement again, plus a list of every change. You see what improved.
Why Percelia
Measurement, not claims
Many agencies say a site is now fast or accessible. We show the number before and after, with the tool and the date.
Our own testing software
It tests on six layers: rules, keyboard, zoom and reflow, the screen reader's view, forms and messages, plus AI judgement. Checked against the official W3C test collection.
How the software testsFixed in code, never covered up
We do not sell an overlay tool that hides faults while the page loads. The change lives in the source code, and that code is yours.
Work samples
Three example sites for made-up businesses, built as for real clients and tested with our software.
For agencies
You sell, we deliver: testing and remediation for your client projects at fixed trade prices, in a report without our logo and with no contact to your client.
The tool behind the work
Our testing software measures every page we build or repair. You can run it on one page for free: enter the address, see the first findings, no sign-up. It is not a full audit, but it is an honest start.
Start the free checkFrequently asked questions
The law in detail- What does it cost?
- That depends on scope and system. After your request we measure and send a fixed price. Work only starts once you agree.
- Do we need a call?
- You do not have to: request, offer, questions and handover all happen in writing, which is usually faster and leaves everything on record. If you would rather talk, call us. The number is in the footer.
- Is my website fully compliant afterwards?
- Nobody can honestly promise that, and no software can either. We fix the measured, named points, prove every change and say openly what cannot be tested automatically.
- Which systems do you work with?
- WordPress, WooCommerce, Shopify, plain HTML, React and Next.js, plus sites from AI tools such as Lovable, Bolt and v0. For other systems we tell you after the request whether it fits.
- What does the free check show?
- It tests one page automatically for common barriers and shows the first findings. It is a start, not a full audit.
What should get better on your website?
Put it in a few sentences. You get a written assessment and a fixed-price offer.
