Different jobs: bug reporting versus client review

Marker.io is designed for teams that want detailed bug reports: the widget collects environment details, and higher plans add console logs, network requests and session replay. That's valuable for QA and engineering teams debugging tricky issues.

ClientTweak is designed for reviews: getting clients, designers and stakeholders to tell you clearly what should change. Reviewers open a link, click the element and comment. You see a screenshot of what they saw and their viewport size, then send the work to your task tool.

No widget to install or remove

A widget needs to be added to every site you review and removed or hidden before launch. ClientTweak loads the site through a proxy instead, so you can review a client's live site without touching its code, and nothing needs cleaning up afterwards.

For the site itself, preview desktop, tablet and phone widths and keep comments scoped to the width they were left on.
