KS Labs A11y Audit · Live in production

Your Site's Health,
Around The Clock.

KS Labs A11y Audit is our own accessibility and performance monitoring platform: automated axe-core WCAG scanning, issue deduplication, and per-page Core Web Vitals with real-user field data measured around the clock. Built and run by us, in production for clients today.

Our Approach

We Audit First.
Always.

Full approach →

We Audit Before We Pitch

"We did our homework before asking for yours." We run accessibility, Core Web Vitals, and SEO audits on your real site and arrive with data, not adjectives.

We Scope Precisely

Fixed-fee milestones for project work. Time-and-materials retainers at a blended senior rate with monthly hours-by-category reporting. No surprise invoices.

We Build With Discipline

Staged deploys, visual regression testing, automated accessibility testing, editor-safe theming. Conformance doesn't drift because we test before every push.

We Stay

Defined SLAs, emergency response at no premium, monthly reporting. The person who answers is the person who can fix it.
