The RedFlag marketing site: oversized "RED FLAG STATUS" type over a dotted wave field, above the line "Scan for WCAG issues, track what needs fixing, and get reports your whole team can read."

An accessibility testing platform that turns one-off audits into a scan, fix and prove loop.

RedFlag browser extension popup on the free plan, offering a single-page scan and a full-site crawl of up to 100 URLs.

Accessibility work in most teams arrives as a six-week audit engagement: a PDF of findings lands, some issues get fixed, and nobody can show which ones. By the next release the report is already out of date.

The problem is not detection: automated rules already catch a meaningful slice of WCAG. It is that findings sit outside the team's workflow, severity is treated as a flat issue count, and there is no defensible way to prove a fix actually landed when procurement asks for conformance evidence.

Founder and product lead for RedFlag, Qern's own product. I own the product decisions, the design and the delivery, including the deliberate choices about what the tool refuses to claim.

Designed the product around four entry points into an existing workflow: a Chrome extension running axe-core locally on the active page, sitemap-driven full-site crawls of up to 100 pages per run on Pro, an issue queue with explicit states (open, in progress, ready to verify, confirmed fixed) behind a weighted per-domain compliance score, and VPAT/ACR plus CSV export generated from the same live dashboard data. Every violation carries its WCAG 2.1 or 2.2 criterion, severity, selector, HTML snippet and fix guidance: the reporting is a view of the issue data, not a separate document to keep in sync.

Built as Qern's own product, which makes the client-facing accessibility practice and the product practice inform each other: the audit work sets the requirements, and building against them exposes where automated tooling genuinely helps and where it cannot.

RedFlag scan results listing accessibility violations, each with its severity, description and rule type.

RedFlag is live and publicly available, free for a single domain with a paid Pro tier, alongside a published blog on accessibility and search. Usage, conversion and revenue figures are not published and are not claimed here.

The hardest product decision was where to stop claiming. Automated rules cover a real but partial slice of WCAG, so RedFlag says that plainly and recommends manual review for the rest, a weaker marketing line and a much stronger product, because a compliance score is only useful if the person relying on it knows what it does not cover.

The RedFlag brand and component system: the logo lockup, typography and colour palette, the card, button and issue-list components built from them, and those components assembled into the browser extension and dashboard.
