An example of a scan of a made-up website: the scanner checks the homepage, then 20 pages, then runs a keyboard test, lists problems such as images with no description, and gives a score out of 100 with a band such as Behind or Almost ready.
Why check your website’s accessibility?
An accessible site works for everyone who visits it. Checking it is the quickest way to know where you stand.
Lower your legal risk
Many accessibility complaints and lawsuits cite problems a check like this catches, such as unlabeled forms and images without descriptions. Finding them first gives you time to fix them.
Reach everyone
About 1 in 4 adults in the US has a disability, according to the CDC. An accessible site works for them, and for anyone on a small screen or in bright sun.
Meet your deadline
State and local governments must meet WCAG 2.1 AA by April 26, 2027, or April 26, 2028 for smaller ones.
A better site for everyone
Clear headings, labels and descriptions make every page easier to use, and search engines read them too.
How it works
Accessibility is not a one-time fix. Four steps on one loop: every recheck shows what to fix next.
01 Scan
Enter a website address. We check the homepage first, then up to 20 pages, the way visitors with disabilities use them.
You get: a score in seconds
02 Understand
Every problem in plain words: what is wrong, who it shuts out, and which problems matter most.
You get: the most serious problems first
03 Fix
Share the report with whoever runs the site, or ask Dynamosys, which runs Accessible Index, for a quote straight from the report. People fix the code; no widgets.
You get: real fixes, not an overlay
04 Recheck
Keep your report to scan again any day and get a fresh check every three months, so new pages don’t slip back.
You get: a dated record of progress
Why Accessible Index
Plain words, not jargon
Every problem is explained by what it does to a real visitor, not by a rule number.
Results in seconds
Your homepage first, then the rest of the pages fill in while you watch.
More than code checks
A keyboard test and a phone-width test, not only the page code, and a free PDF check too.
Honest about what it can see
We never call a site compliant, and we publish exactly how every score is worked out.
No widgets, no shortcuts
We never sell an overlay. A widget cannot fix a site’s own code, and sites using them are still sued.
Built on open standards
Our scanner tests against WCAG with open, industry-standard accessibility rules, so anyone can repeat a result.
For federal, state and local governments
The public index: how every government website measures up
Federal websites, every state government and the counties, cities and towns of Maryland and Virginia are in the index now. Each government gets its own page with its score, its deadline and what stops people using its site, checked again every three months.
Questions people ask
Straight answers about the check, the index and what we do with your data.
Still have a question?
Write to us. A person, not a bot, reads and answers every message.
Found a barrier on this site? Tell us. We fix our own problems first.
Is Accessible Index really free?
Yes. Checking a site is free, with no account. A full report for a business site asks for your email so we can send you a link to keep it; government pages in the index are always public. Accessible Index is run by Dynamosys, a web firm that offers to fix what the check finds. You never have to use it.
Does a good result mean my site is ADA compliant?
No scanner can tell you that. Automated checks reliably find many problems, but some need a person to judge, such as whether an image description is accurate. A site with no automated failures is a strong start, not a guarantee.
Which laws and standards do you check against?
WCAG 2.1 AA, the standard the ADA Title II rule sets for state and local governments and the Section 504 rule sets for health and human services providers. It also covers the WCAG 2.0 that Section 508 uses for federal sites, and it is the standard most ADA Title III settlements with businesses point to.
Do you change my website or need access to it?
No. We read your public pages the way a visitor does. We never sign in, submit a form or change anything.
How many pages do you check?
Up to 20: your homepage first, then one of each kind of page, with forms and search ahead of the rest. We also check how pages fit a narrow phone screen and press Tab through your homepage the way a keyboard user would.
Will an accessibility widget fix my site?
No. Widgets, often called overlays, change how a page looks without fixing its code, and sites using them are still sued. In 2025 the Federal Trade Commission ordered one overlay company to pay $1 million for claiming otherwise.
Do you sell or share this data?
We never sell personal information, and never hand over email addresses or lists of sites to vendors, law firms or anyone looking for leads. Results for government websites are public: that is the index. A report on any other site is unlisted, seen only by people with its link. Companies that run parts of the site for us, such as hosting and email, handle data only to provide that service; our privacy policy names them. Researchers can get bulk access to the index’s results, which hold no personal information, under a signed agreement that forbids contacting anyone in it. We disclose information only when the law requires it, and we never publish which company runs a website or who works there.
