From Strategy to Code

Usability Testing Agency · Moderated, Unmoderated, Accessibility Audits

Usability testing as a continuous practice — not a pre-launch event. Moderated, unmoderated, expert reviews, and accessibility audits, with the synthesis discipline that turns sessions into product decisions.

Why HXRL

Our point of view

Most usability testing is theatre — a launch checklist run too late to change anything. We embed it before, during, and after design — and we tie findings to a backlog the product team actually pulls from.

Outcome

Usability findings the product team actually ships against — not a slide deck filed away after launch.

What we ship

Usability Testing

Concrete deliverables — not adjectives. Each engagement scopes which of these are in play and what success looks like for them.

01Moderated usability testing (in-person and remote)
02Unmoderated testing (Maze, UserTesting, Lookback)
03Expert reviews and heuristic evaluations
04Accessibility audits (WCAG 2.2 AA / AAA, ARIA, keyboard, screen reader)
05Research synthesis and product-team backlog hand-off
FAQ

Questions clients actually ask

Drawn from sales calls, not SEO filler. Want a question added? Drop it in the form on this page — we update from real enquiries.

Moderated or unmoderated?+

Both — moderated for new flows where you need to ask why, unmoderated for iterative testing of validated flows. Each costs differently and answers different questions.

Sample size — how many users?+

5–8 for qualitative pattern-finding. 30+ when measuring quantitative outcomes. We don't conflate the two.

Accessibility audits — manual, automated, or both?+

Both. Automated (axe-core, Pa11y) catches the obvious. Manual (keyboard, screen reader) catches the rest. Either alone is incomplete.

Continuous testing — how do you set it up?+

Recruiting pool kept warm, lightweight session cadence (every 2 weeks), and synthesis published into a repo the product team subscribes to.
