Catch accessibility problems while you build, not after the audit.
Contrastic checks your website while your team writes it. Each problem shows up in the editor and in the pull request, with a clear fix. Your team fixes it in minutes, before a user ever meets it.
Accessibility is not optional any more
1 in 6 people has a significant disability. For them, your website works only when it is accessible.
Your users
1.3 billion people worldwide. And everyone, sometimes: with a broken arm, or in bright sunlight.
The law
Since June 2025, the European Accessibility Act asks for accessible digital products and services.
Quality
Clear structure and good labels make a site better for everyone, and for search engines too.
Today, teams find the problems too late
Most teams test accessibility in an audit, after the release. By then, each problem costs much more to fix.

The euro signs show the cost of a problem at each step, as an indication. They are not a measurement.
What Contrastic does for your team
Contrastic moves accessibility to the start of the work, where a fix is fast and cheap. Your developers get feedback the same way they get it for every other mistake.
Feedback while you type
Problems show up in the editor, the moment a developer writes them. In VS Code, Zed and IntelliJ.
A gate in every pull request
A serious problem stops the merge. Nothing inaccessible reaches your users by accident.
A clear fix, not a report
Each finding says what is wrong, where it is, which WCAG rule it breaks and how to fix it.
Quiet enough to trust
When Contrastic is not sure, it does not guess. Few false alarms means the team keeps listening.
Ready for AI coding
AI assistants copy the accessibility bugs of the web. Contrastic gives them the same feedback, so they fix their own mistakes.
Code and browser together
It reads your source code first and checks the live page as a safety net. One finding per problem, never two.

Results
- 169
rules for WCAG 2.2, the standard behind the law
- 96%
of the level A and AA criteria have at least one check
- < 3%
false alarms in our test sets, with a goal of less than 10%
- < 10 ms
to check a file of 2,000 lines, fast enough for every keystroke
We measured the false alarms on our demo shop (2.2%) and on the W3C test cases (2.9%). An automated check covers only part of each criterion, so it does not prove that a site conforms to WCAG. People still test what a tool cannot decide.
