Find what's broken
before you ship it.

Two audits in one. Point it at a live URL and it crawls the whole site, uses every page with a keyboard, and checks every link. Or hand it your source and it reads the code for hardcoded secrets, injection, auth gaps and unsafe payment logic. Both end the same way: plain-English findings, and the prompt that fixes them.

Or try:
How deep

Why this matters

Software ships faster than anyone can check it.

95.9%
of the top million homepages fail WCAG, averaging 56 failures eachWebAIM Million, 2026
5,000+
web-accessibility lawsuits filed in the US in a single year2025 filings, federal and state
113
of 401 sites sued in one month were already running an accessibility widgetJuly 2026 filings

That last number is the one worth sitting with. The dominant fix on the market — a widget that patches the page at runtime — did not stop those sites from being sued, because it never changed the underlying code. Meanwhile an app built in an afternoon ships with no security headers, an exposed .env, dead links, and a sign-up button keyboard users can never press. None of it is visible unless someone goes looking, and looking by hand takes a day.

What it checks

What broke
Uncaught exceptions, APIs returning 500s, files that 404. Things already failing for every visitor.
Whether a keyboard works
We press Tab through your whole page. Buttons nobody can reach, focus you can't see, dead ends.
What the server gives away
Missing security headers, cookies without flags, and .env files left publicly downloadable.
What you forgot
No meta description, no share preview, no sitemap, still set to noindex from staging.
Every link on the site
We request each one. Internal links to pages that no longer exist, and outbound links that died years ago.
How it behaves on a phone
Re-rendered at 390px. Content running off the edge, tap targets too small to hit, text too small to read.

What it can't check

Axiom never attacks a running server — no probing rate limits, forcing logins, or firing injection payloads at a host you may not own. That is unreliable and, in most places, illegal. Instead it finds those same classes of bug the safe way: the live audit reads only what a page volunteers to any browser, and the code audit reads the source you own. Everything it reports, it observed.
