Sizing your plan#
Multiply pages × scans per month, then add 10 per site you add.
| Site size | Weekly | Monthly | Daily |
|---|---|---|---|
| 50 pages | ~215 | ~50 | ~1,500 |
| 100 pages | ~430 | ~100 | ~3,000 |
| 500 pages | ~2,150 | ~500 | ~15,000 |
| 1,000 pages | ~4,300 | ~1,000 | ~30,000 |
| 5,000 pages | ~21,500 | ~5,000 | ~150,000 |
Weekly is the right default. Daily above ~2,000 pages exceeds every published plan.
Report buckets#
| Bucket | Meaning | Act on it? |
|---|---|---|
| Violations | Confirmed problems | Yes — your work list |
| Alerts | Probably fine, worth a glance | If time allows |
| Passes | Checks that passed | No |
| Incomplete | Scanner could not decide | Yes — needs a human |
Severity order#
Fix top to bottom.
| Severity | Meaning | When |
|---|---|---|
| Critical | Blocks use of the page entirely | Now |
| Serious | Major barrier, many users | This sprint |
| Moderate | Real but workable | Backlog |
| Minor | Polish | When convenient |
WCAG failure vs best practice#
| Tag on the finding | What it means |
|---|---|
WCAG A / WCAG AA + criterion number | A real failure against the standard. Counts for conformance and legal exposure. |
WCAG BEST PRACTICE | A recommendation, not a WCAG failure. Worth fixing; doesn't affect conformance. |
When reporting to a client or a board, count only the tagged criteria. The headline score includes best-practice rules and weights by affected elements, so it reads far worse than your actual conformance gap.
AI fix statuses#
| Status | What to do |
|---|---|
| Applied / ready | Review, then apply |
| Needs your input | Replace the [PLACEHOLDER] with your own wording |
| Dev required | A developer must choose between the listed options |
| Decide | Automated validation failed — review manually |
Never apply a suggestion unread. A wrong aria-label is worse than none.
Score bands#
| Score | Read |
|---|---|
| 90–100 | Good. Mostly best-practice items left. |
| 75–89 | Typical. A few real problems, usually template-level. |
| Below 75 | Prioritise. Likely contrast or labelling failures sitewide. |
A score is not a compliance certification. Automated testing reaches roughly 20–40% of WCAG success criteria.
Where things live#
| I want to… | Go to |
|---|---|
| See overall health | Overview |
| Scan a page or the whole site | Pages |
| Scan a URL on any domain | New scan (top bar) |
| See scans not tied to a site | Ad-hoc scans |
| Check URL discovery | Sitemaps |
| Check a PDF | PDF documents |
| See whether we're improving | Score trends |
| Build a conformance report for buyers or auditors | Conformance report |
| Set up recurring scans | Settings → Scanning |
| See where credits went | Settings → Credit history |
| Change plan | Settings → Plan and billing |
| Invite a colleague | Settings → Team (needs Pro or Agency) |
Scan scheduling options#
Settings → Scanning, per site: Change opens the choice of Off, Daily, Weekly or Monthly, each with what a run costs. Off is the default: nothing recurring happens until you change it.
Free plan limits#
- 1 site, and no delete control in the portal. Choose your first site deliberately.
- Scanning a page on another domain isn't blocked (1 credit, under Ad-hoc scans); only tracking a second site is.
- 100 credits ≈ one site plus ~90 page scans.
- Need more sites? Individual Lite ($49) already gives 3; you don't need an Agency plan.
Assistive technology Zylyn's reviewers use#
NVDA and JAWS (Windows screen readers), VoiceOver (Apple), keyboard-only navigation, high-contrast mode, and 400% zoom reflow.
