## Beschreibung

**Find out where your site fails WCAG — before anyone else does.**

Install the plugin, click one button, and QAProof loads your home page in a real

browser and checks it against **WCAG 2.1 Level AA**. You get a score and the issues
it found straight away. **No account, no API key, nothing to configure for that 
first check.

It is an accessibility scanner, not an overlay or a toolbar: it changes nothing

on your site and shows nothing to your visitors. It finds a11y defects and tells
you where they are, so you or your developer can fix them properly — the approach
the accessibility community asks for, and the one that stands up when someone checks
your work against WCAG, EN 301 549, the European Accessibility Act (EAA) or Section
508.

#### What it checks

QAProof runs the checks that can be made automatically, and tells you exactly
 where
each one failed:

 * **Colour contrast** (color contrast) — text and UI borders measured against the
   4.5:1 and 3:1 thresholds, with the computed colours it used.
 * **Images without alt text** — and alt text that is a file name, a placeholder
   word, or far too long.
 * **Form fields without labels** — including fields whose only label is a placeholder,
   which disappears as soon as someone types.
 * **Keyboard focus** — controls with `outline: none` and no visible focus style,
   which strand keyboard users.
 * **Heading structure** — skipped levels, empty headings, more than one H1.
 * **ARIA** — invalid roles and roles missing the attributes they cannot work without.
 * **Landmarks** — content sitting outside any navigable region.
 * **Touch targets** — controls below the 24×24px minimum.
 * **Page language** — a missing or malformed `lang` attribute, which decides how
   a screen reader pronounces your page.

Every finding names the **WCAG success criterion** it relates to, the **exact
 element
(
CSS selector and a snippet of the source) and what was measured —
 the actual contrast
ratio, the actual size — so you can check it yourself rather than take our word 
for it.

#### An honest word about „compliance“

Automated checks find a meaningful share of accessibility problems, and they
 find
them in minutes. They **cannot** tell you that a site is compliant.

No automated tool can judge whether your alt text is _meaningful_, whether your

tab order makes sense, or whether a screen reader user can actually complete your
checkout. Standards like **EN 301 549**, the **European Accessibility Act, Section
508 and Italy’s AgID guidelines all expect manual testing with a keyboard and a 
screen reader.

Use this to find what can be found quickly, to measure whether you are getting
 
better, and to hand a developer a precise list. Do not use it as a compliance certificate—
and be sceptical of any tool that offers you one.

#### Check the whole site, not one page

**Site Audit** finds your pages from your sitemap and checks every one of them,

then does the thing a page-by-page list cannot: it groups the findings.

On a WordPress site most defects live in a template, so the same problem
 appears
on every page that uses it. Instead of reporting it forty times, Site Audit says**„
this one fix covers 38 pages“** — and sorts the list so the fix with the widest 
reach is at the top.

Run it again after the work is done and you get the other half: **what changed
 
since last time.
 How many issues were resolved, which ones, on which pages,
 and
anything new that appeared. That is the part you can show a client.

Coverage is always stated plainly — how many pages were checked out of how many

were found, and which ones could not be loaded. A page behind a bot wall or one 
that times out is reported as exactly that, and never counted as passing.

How many pages one run checks depends on your plan: **5 on the free plan**, 50
 
on Pro, 150 on Business. The report always says how many it found so you can see
what was left out. When a run finishes, a copy of the report is emailed to the address
on your account.

#### Beyond accessibility

The same plugin also covers the visual side of QA, if you need it:

**Design Fidelity**

**Does the live site actually match the design?**

**The situation:** „I sent the mockup to the developer and the result looks nothing
like it. I spend hours comparing elements by eye — and still miss things.“

**What you get:** Connect your Figma account and pick a design — QAProof compares
it against your live page. Every layout shift, color mismatch, typography difference,
and spacing issue is flagged with its exact location and a copy-paste CSS fix.

**Responsive Testing**

**Does your site hold together on every screen size?**

**The situation:** „Everything looks fine on my phone. Then a client calls from 
their iPad and says half the page is broken.“

**What you get:** Your page is tested at five viewports — desktop, tablet (portrait
and landscape) and mobile (portrait and landscape). The AI identifies overflow, 
broken stacks, illegible text, and layout failures across all five viewports — **
not just the device you happened to check.**

**Visual Regression Monitoring**

**Did the last update break something you haven’t noticed yet?**

**The situation:** „After a plugin update, the header shifted and a button disappeared.
We only found out a week later — when a client complained.“

**What you get:** Set a baseline screenshot of any page. QAProof re-checks it on
your schedule (daily, weekly or monthly) and emails you when the score drops below
your threshold. **Catch broken deploys in hours, not weeks.**

**Design Audit (Design Debt Score)**

**How consistent is your design system — really?**

**The situation:** „Our site uses 47 shades of gray and 12 different font sizes.
There’s a design system, but nobody follows it. And we have no way to measure how
bad it’s gotten.“

**What you get:** QAProof reads your live design tokens directly from the DOM — 
colors, fonts, spacing, CSS variables — and grades your design system’s internal
consistency on a score from 0 to 100. 0 is ideal. See exactly **where the drift 
started.**

#### Who uses QAProof?

QAProof works equally well for non-technical site owners and experienced development
teams.

 * **Agencies & studios** — audit a client site in minutes instead of an afternoon,
   and hand over a PDF that names the WCAG criterion and the element for each finding.
 * **Public-sector sites** — councils, schools and agencies working to EN 301 549,
   the European Accessibility Act or AgID: find what is findable automatically, 
   then put your manual testing time where it counts.
 * **Freelancers** — prove your work matches the design with objective data. A score
   is more convincing than „trust me.“
 * **In-house teams** — set up monitors on your key pages and get alerted the moment
   a deploy breaks something.
 * **WordPress site owners** — no code, no complexity. Install the plugin and click
   one button.
 * **QA engineers** — help identify, reproduce, and investigate issues quickly, 
   making the development process faster and more reliable.
 * **Designers** — see exactly where your design was implemented incorrectly, and
   hand developers the precise CSS they need to fix it.

#### Getting started

**Your first check needs nothing but the plugin:**

 * Install and activate QAProof.
 * Open the **QAProof** menu and click **Check my site**.
 * A real WCAG 2.1 AA check of your home page runs — usually 1–2 minutes — and you
   get a score and the issues found.

**To go further**, connect a free account (Settings  it takes a minute) and you 
can:

 * audit any page, not just the home page, and pick WCAG Level A, AA or AAA;
 * see every issue rather than the first few, each with its element and a recommendation;
 * export a PDF or email the report;
 * set a monitor that re-checks a page on a schedule and tells you when the score
   drops;
 * run the visual tests below.

#### What you get in every report

 * **An overall quality score** from 0 to 100 — clear, communicable, and objective.
 * **Category-by-category breakdown** with visual charts.
 * **Every issue listed with its exact location** on the page.
 * **Ready-to-paste CSS fix recommendations** — not „something looks off“ but „add
   margin-top: 16px to .header-nav“.
 * **PDF reports** — the findings, the elements and the measured values, ready to
   send to your client in one click.
 * **Email reports** — send directly from the interface without downloading.
 * **WCAG level selector (A / AA / AAA)** — adjust audit strictness to match your
   requirements.
 * **Saved designs** — save a Figma design once, reuse it across all future tests.

#### Why choose QAProof over separate tools?

The market has tools for design comparison. Separate tools for regression. Separate
tools for accessibility. **QAProof combines all five in one platform.**

 * WCAG 2.1 accessibility audit — Level A, AA, AAA
 * A real result before you create an account
 * Design vs. live page comparison
 * Figma tool support
 * Responsive testing across 5 viewports
 * Visual regression monitoring
 * Design Debt Score
 * WordPress plugin with built-in admin UI
 * Scheduled automatic monitoring
 * PDF reports
 * AI-generated CSS fix recommendations

#### Start for free today

Install the plugin and click **Check my site**. You will know where your site stands
before you have typed an email address.

## Installation

 1. Install the plugin from the WordPress plugin directory (or upload the ZIP via Plugins
    Add New  Upload).
 2. Activate it — a **QAProof** menu appears in your admin sidebar.
 3. Open **QAProof** and click **Check my site**. Your accessibility score and the 
    issues found appear in a minute or two. No account needed for this.

To audit other pages, see every issue, export PDFs or set up monitoring:

 1. Create a free account at [qaproof.io/signup](https://qaproof.io/signup) and copy
    your API key (API Keys page).
 2. Paste it into **QAProof  Settings** and save.

## FAQ

### Do I need an account?

Not for the first check. Install the plugin, click **Check my site**, and you get
a real score and the issues found on your home page — no account, no API key, no
card.

An account (free) is what unlocks auditing other pages, seeing every issue rather
than the first few, PDF export and scheduled monitoring.

### Is QAProof free?

The WordPress plugin is **free and open-source** (GPL-2.0+). The first check of 
your site needs no account at all.

The QAProof service then has a **Free plan**: 10 AI generations as a one-time trial—
they do not reset monthly — 1 monitor, and 7 days of test history. If you sign up
with an email address you get 3 of those 10 until you verify the address; signing
in with Google or GitHub gives you all 10 immediately. Paid plans (Pro, Business,
Scale) add more generations, monitors and history. Full pricing at [qaproof.io/pricing](https://qaproof.io/pricing).

### Is this an accessibility overlay or a toolbar?

No. QAProof adds nothing to your pages and your visitors never see it. Overlays 
and toolbars try to patch a site from the outside at page load; they are widely 
rejected by disabled users and by accessibility professionals, and in 2025 the US
Federal Trade Commission fined one overlay vendor $1,000,000 over claims about what
its script achieved.

QAProof does the opposite job. It reads your page, tells you which WCAG success 
criterion each defect relates to and which element is at fault, and then gets out
of the way so the problem can be fixed in your theme or content — where it actually
lives.

### Does this make my site legally compliant?

No, and no automated tool can. It finds the problems that can be detected automatically—
a large and useful share of them — but judging whether alt text is meaningful, whether
the tab order makes sense, or whether someone using a screen reader can finish a
purchase needs a person. EN 301 549, the European Accessibility Act, Section 508
and AgID all expect manual testing alongside automated checks.

### Do I need a Figma account?

Only for Design Fidelity (Figma vs live page). Responsive, Accessibility, Design
Audit and Visual Regression need just a URL.

### What information does QAProof send when I run a test?

Only what you explicitly submit: the **URL of the page** you want to test and, for
Design Fidelity, the **Figma design link**. QAProof never reads your post content,
user accounts, visitor data, passwords, or any other information from your site.

Every request also carries a normal User-Agent identifying the plugin version and
your WordPress and PHP versions — the same thing any HTTP client sends — so we can
tell which versions are in use when something breaks. Emailed reports carry the 
address you send them to, and the feedback form carries your WordPress user ID and
your site’s home URL so we can reply about the right site.

The one request that happens without an API key is the first check: when you click**
Check my site**, the plugin sends your site’s public home page URL to api.qaproof.
io so it can be loaded and audited. Nothing is sent until you click that button.

### Where are my test results stored?

Results are stored securely in your **QAProof account**, scoped to your workspace.
The plugin itself stores only your settings (API key, saved designs as name + Figma
link, notification and test preferences). Test results are not saved to your WordPress
database.

### How long does a test take?

Most tests finish in a few minutes (typically 1–5). **Design Fidelity:** 1–3 minutes.**
Responsive Testing:** 2–4 minutes (5 viewports). **Accessibility Audit:** 2–5 minutes.**
Design Audit:** 1–3 minutes.

### Does the plugin work on WordPress Multisite?

Yes. The plugin can be network-activated, and each site in the network manages its
own settings and API key independently. Note that test history lives in the QAProof
account behind the API key — sites that share one API key share one test history.

### What happens if I enter a wrong API key?

The API rejects it and the plugin shows an error; no test runs until you enter a
valid key. You can update your key at any time.

We use QAProof daily in our QA workflow to compare design mockups with live pages.
The AI catches pixel-level differences that manual review misses.Setup is straightforward,
the plugin integrates cleanly into WordPress admin.Great time-saver for teams that
care about design accuracy.

## Änderungsprotokoll

#### 1.0.43

 * **Reports no longer name CSS classes your page does not have.** To photograph
   a page in its final state the audit marks lazy-loaded images, animations and 
   collapsed menus as loaded, and those marker classes were leaking into the selectors
   in your report — so a finding could point at `img.img-fluid.lazyloaded`, an element
   nowhere in your HTML. Runtime state such as the active carousel slide is left
   out too, which also stops one defect being listed several times depending on 
   which slide happened to be showing.
 * The package no longer carries a second copy of Chart.js. Chart.js v4 publishes
   only minified builds, so the 208 KB `chart.umd.js` shipped next to the file the
   plugin loads was a duplicate that was never loaded. THIRD-PARTY-NOTICES.txt now
   says exactly what is bundled.

#### 1.0.42

 * Settings no longer says „This site is connected to your QAProof account“ when
   the saved key is one the API rejects. It says a key is saved, and lets the account
   panel — which actually asks the API — report whether it works.

#### 1.0.41

 * Added the GPL-2.0 LICENSE file that THIRD-PARTY-NOTICES.txt has been telling 
   you to read. The build now refuses to package without it.
 * Category names in the report now describe what is actually in them: an invalid
   ARIA role was filed under „Spacing & Layout“ and a broken page language under„
   Text Readability“.

#### 1.0.40

 * **A mistyped API key now tells you so.** Settings queued an error and never printed
   it, so pasting a malformed key returned a page that silently did nothing. Saving
   correctly says so now too.
 * **The PDF no longer carries a „verified“ seal.** Nothing verified it — there 
   was no signature and nothing a recipient could check. It says what it is: an 
   automated check. This plugin’s own FAQ tells you to be sceptical of exactly that
   kind of mark, and it should hold itself to that.
 * **The readme now matches the code** on what leaves your site (the plugin version
   and your WordPress and PHP versions travel in the User-Agent, as with any HTTP
   client), on Site Audit’s per-plan page limit, and on the fact that a finished
   site audit emails you a copy.
 * Fixed a finding that contradicted itself on a default WordPress theme, reporting
   content „outside any landmark region“ while listing the landmarks it was inside.
 * Errors from the analysis service are now written for you rather than for whoever
   operates it.

#### 1.0.39

 * **Listing rewritten so the plugin can actually be found.** The directory search
   could not match us on „EAA“, „a11y“ or „accessibility scanner“ at all, because
   those words appeared nowhere in this file. They do now, and the tag that pointed
   at a four-plugin corner of the directory has been spent on ones people search.
 * **New FAQ: is this an overlay or a toolbar?** It is not, and the difference matters
   enough to say so plainly.
 * The accessibility report is now the first screenshot, instead of the dashboard.

#### 1.0.38

 * **Download the site audit as a PDF.** One file with the score, what changed since
   your last audit, the fixes that cover the most pages, and the per-page table —
   the report you send to a client. It states plainly how many pages were checked
   out of how many were found, and which could not be loaded.

#### 1.0.37

 * **Site Audit: check the whole site, not one page.** A new page finds your pages
   from your sitemap, checks every one against WCAG 2.1 AA, and groups the findings—
   so a defect in a template reads as „this one fix covers 38 pages“ instead of 
   being listed thirty-eight times.
 * **See what you fixed.** Run it again and the report opens with what changed since
   last time: how many issues were resolved, which ones, on which pages, and anything
   new. The re-scan deliberately re-checks the same pages so the comparison is like
   for like.
 * Coverage is stated plainly — how many pages were checked out of how many were
   found, and any page that could not be loaded is reported as that rather than 
   counted as passing.
 * Fixed: secondary text in the plugin’s own admin screens did not meet the WCAG
   1.4.3 AA contrast threshold (3.87:1 on light, 3.50:1 on dark). Both themes corrected.

#### 1.0.36

 * Listing name now says what else the plugin does: „Accessibility Checker & Visual
   QA“.

#### 1.0.35

 * **Connecting an account is one click.** „Connect a QAProof account“ opens qaproof.
   io, signs you in or creates a free account, and brings you back with the API 
   key already saved. Pasting a key by hand still works.
 * The first-run check lets you change the URL, so a local or staging install is
   no longer a dead end, and warns before running if the address cannot be reached
   from the internet.

#### 1.0.34

 * **You can now see a real accessibility score without an account.** The Dashboard
   runs a WCAG 2.1 AA check of your site on request — no API key, nothing to configure—
   and shows the score and the issues found. Connect a free account when you want
   the rest.
 * The URL fields on the Tests and Accessibility pages are pre-filled with your 
   own site address instead of being empty.
 * Listing rewritten around what the plugin is mostly used for: accessibility.

#### 1.0.33

 * Plugin homepage link now points to qaproof.io.
 * Settings: account panel says „1 monitor“ (was „1 monitors“).
 * Listing: screenshot captions added; accessibility audit description clarified(
   automated WCAG 2.1 check, with a link to the free no-signup checker).

#### 1.0.32

 * Every accessibility and responsive finding now shows WHERE it is: the exact CSS
   selector (click to copy) and a snippet of the element’s source, right on the 
   finding card and in the PDF report.
 * Tests page now discloses that AI element detection uses 1 AI generation before
   you run it.
 * Plugin copy aligned with actual behaviour — descriptions, tooltips and button
   labels now say exactly what each action does.
 * Compatibility confirmed with WordPress 7.1.
 * Responsive Test is now the default test type — it needs only a URL, no design
   file.
 * Quota and limit errors now show a working upgrade/verify link instead of a generic
   error.
 * Added a „Create a free QAProof account“ link to Settings for new installs.
 * Dashboard „Upgrade Plan“ now opens your QAProof billing page.

#### 1.0.30

 * Fidelity audit improvements and stability fixes.

#### 1.0.29

 * Report fidelity improvements across all five test types.
