UX Check review
A free Chrome extension for documented heuristic reviews, not participant-based usability testing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
UX Check is a free Chrome extension for developers and designers who need to evaluate website usability without recruiting or observing test participants. Its workflow centers on structured heuristic reviews: evaluators can work from Nielsen’s 10 usability heuristics or create a custom checklist, then document interface issues as they review a site. Personal and commercial use are available at no cost, making the product suited to solo practitioners and small teams that want a lightweight review process.
The standout feature is the way UX Check turns a browser-based review into a documented deliverable. Evaluators can add notes to issue annotations, capture UI screenshots, and export findings with those screenshots to a Word document. That combination supports a practical handoff from inspection to written recommendations, particularly when a team needs a record of observed interface issues rather than a live research session. Custom heuristic lists also make the extension applicable to review frameworks beyond Nielsen’s standard checklist.
Its focus is intentionally narrow. UX Check provides a heuristic-evaluation workflow, but not participant recruitment, moderated sessions, or unmoderated sessions. It is therefore a fit for developers, designers, and small teams conducting internal website reviews, especially when a free browser extension and Word export match the process. Teams that need to observe users, manage testing sessions, or run participant-based usability research should choose a broader usability testing platform instead. Support is provided by email, and the product is deployed as a Chrome extension.
