What Heurio is
Heurio is a collaborative website review tool for design, development, and marketing teams. Reviewers attach comments, notes, suggestions, and severity levels directly to elements on live webpages. They choose what to flag; the Chrome extension does not scan pages automatically. Built-in heuristic guidelines support structured evaluations, and teams can create custom heuristics. Projects can be shared by link or team invitation. Professional includes PDF and CSV export, unlimited projects, and up to ten seats. Organization adds centralized project management, activity logs, and team management for workspaces from ten seats. Heurio runs as a Chrome extension and supports Chromium-based browsers including Edge, Brave, Arc, and Opera, as well as a web platform. The trial workspace provides full access for three days, costs nothing, requires no credit card, and allows up to three seats. Professional costs $19 a month per seat. Heurio is headquartered in Budapest, Hungary; its privacy policy identifies Apptum Hungary Ltd. as controller and cites GDPR and Hungarian law.
