About WCAG Checker

Why This Tool Exists

WCAG Checker was built to solve one focused problem well, without asking you to sign up, install anything, or hand over your data. Too many tools on the internet wrap a simple utility in an account wall, an email capture, or a heavy SaaS interface. This one doesn't.

Our thesis is simple: the best small tools are ones you can use in under ten seconds, trust with sensitive inputs, and come back to any time without friction. That's the bar we hold ourselves to.

How It Works

WCAG Checker scans websites for WCAG 2.1 AA/AAA and WCAG 2.2 AA accessibility issues and generates fix suggestions using the open-source axe-core engine. The axe rules run inside a sandboxed iframe in your browser — your page HTML and every generated report stay on your device. We never receive, log, or store the URLs you scan or the HTML you paste.

The only network call is a lightweight server-side fetch that retrieves the public HTML of the URL you enter (so we can sidestep CORS). That request proxies through our server and then returns the raw HTML straight to your browser — we do not persist it anywhere.

Our Privacy Philosophy

We do not collect, store, or transmit the data you enter into the tool. There is no database of user submissions because there is no submission to the server in the first place. The only data we see is standard web analytics: page views, referrers, rough geography, browser — the aggregated kind of data that every website receives.

Who Built This

WCAG Checker is built and maintained by TJ (Tushar Jaitly), a Solution Architect who spends his nights and weekends shipping small, focused tools that scratch real itches. The broader portfolio is a collection of utilities — each solving one problem, each free, each privacy-first.

You can find the rest of the portfolio and follow along on GitHub.

How This Tool Stays Free

WCAG Checker is funded by non-intrusive display advertising (Google AdSense) on some pages. That covers hosting and keeps the tool free for everyone. If you want to support it without seeing ads, sharing the tool with someone who needs it is the best thing you can do — word of mouth is how a free utility survives.

Tech Credits

WCAG Checker is built with Next.js, React, TypeScript, and Tailwind CSS, and the accessibility rules come from axe-core by Deque Labs. It is hosted on Vercel. Thank you to all the open-source maintainers whose work makes this possible.
