Coverage
Past the per-page ceiling
WAVE is great for "check this page". A11y Pulse answers "how is the whole site doing, and did anything regress overnight?", without anyone needing to remember to paste URLs into a form.
Whole site, every day
A11y Pulse vs WAVE by WebAIM
WAVE checks one page.
A11y Pulse watches the whole site.
WebAIM built the developer-favourite per-page checker. We built the
continuous monitor for the things WAVE was never designed to do —
daily coverage, regression alerts, and stakeholder-ready reports.
What is WAVE?
WAVE is a suite from WebAIM, and the comparison depends on which piece you mean. WebAIM is explicit that they don't offer site-wide monitoring; they hand that use case off to Pope Tech, a partner platform that wraps the WAVE engine in a hosted dashboard.
Web checker wave.webaim.org
Free, fast, beginner-friendly. Paste a URL, get an
icon-overlay rendered onto a recreated page. One page at a
time, no history.
Browser extension Chrome · Firefox · Edge
Same engine, same overlay, but local — sees authenticated
pages, dev environments, and anything with cookies the
public checker can't.
WAVE API Credit-based
$0.025–$0.04 per page at bulk rates. The basis for most
WAVE-powered third-party tools. Build the dashboard, alerts,
and reporting yourself.

Developer spot checks
WAVE's strengths — the in-page visual overlay and free per-page checker — are unmatched for ad-hoc developer review. They were just never the goal of a monitoring product.
Why teams switch to A11y Pulse
Three things WAVE was never built to do
WAVE's per-page overlay is genuinely useful for developer review. Production accessibility needs the layers around it.
Reporting
Reports built in, not bolted on
WAVE doesn't produce a stakeholder-friendly report. Monthly digests, trend charts, and Slack alerts on regression are first-class in A11y Pulse, not something you build over the API.
Stakeholder-ready PDF
Cost arithmetic
Flat fee beats credit math
A 200-page site scanned daily is 6,000 credits a month — about $150 on the WAVE API at the bulk rate. A11y Pulse Growth covers the same scope with the dashboard, alerts, and reports included.
$49 vs ~$150 / month
Where we fit
Daily axe-core scans, triaged for you
A11y Pulse runs axe-core against your live site every day. Pages are discovered from your sitemap, by crawling, or from a curated URL list. Each page loads in real Chrome so JavaScript-rendered content and authenticated flows are covered, and issues come into a triage-first dashboard you can filter, group, and watch over thirty days. Keep the WAVE extension installed for spot checks — they pair well. A 200-page site scanned daily is 6,000 credits a month on the WAVE API — about $150 at the $0.025 bulk rate, before you've built any UI. Growth covers the same scope for $49 with the dashboard included.
- axe-core daily across your full sitemap
