Weekly accessibility monitoring that shows what changed.
AccessDiff scans your websites every week with automated checks against WCAG 2.2 AA, puts what is new and what was fixed at the top of the report, and sends it to whoever owns the fix.

What AccessDiff does
Scans every week, by itself
Up to 25 pages per site, found through your sitemap and links, with a polite crawler that respects robots.txt.
Leads with the diff
Every report opens with the issues that are new and the ones that were fixed since the last scan, so a regression from a deploy is the first thing you read.
Explains each fix
Each issue shows where it is on the page (selector and element) and how to fix it, from the axe-core rule documentation.
Reports you can forward
PDF and HTML reports with an email summary and a score history. The Agency plan puts your own name, logo and colour on them.
Who it’s for
- Agencies that look after many client websites
- In-house web and product teams who ship every week
- Anyone who needs a dated, forwardable record of automated accessibility checks
How it works
- Add a site. AccessDiff scans it straight away.
- Every week it scans up to 25 pages again and compares them with the last scan.
- You get the report by email: new issues first, then what was fixed and what is still open.
- Forward it to the developer or client who owns the fix, or pull the results through the API.

Every plan includes the web app, the API and the MCP server. Annual plans cost ten months. Refunds within 14 days, no questions asked.
Agents: pay per scan.

Agents start the same scan with one POST, described by an OpenAPI 3.1 document, or through the MCP server. Scans count against the plan’s allowance and are billed per scan past it, at the price in accessdiff.com/llms.txt.
Questions about AccessDiff
Does an automated scan find every accessibility problem?
No. Automated checks find a share of the issues WCAG covers. AccessDiff runs them every week and shows what changed, so new problems surface quickly; testing with a keyboard and a screen reader is still needed for the rest.
How many pages does it scan?
Up to 25 pages per site on every plan, found through the sitemap and the links on your pages.
Can I send the report to a client?
Yes. Reports come as PDF and HTML, and on the Agency plan they carry your own name, logo and colour.
