Markup.io is for many reviewers approving a file; Userback is for feedback from a live site that needs the browser's evidence. Markup.io's workspace is $79 a month with unlimited members and more than thirty file types. Userback has two free seats, then Team at $29 a month billed annually, with session replay from Business.
A review tool for files and websites, sold by workspace rather than by seat, where collaborators join as guests without registering and more than thirty file types, video included, take comments.
A feedback platform with a four-step ladder, opening up AI insights, replay and mobile SDKs as a team moves up it.
Markup.io is a review tool for files and websites, sold by workspace rather than by seat. Every plan carries unlimited members, admins and guests, collaborators join without registering, and comments go on any of more than thirty file types, video included. Its site does not mention console logs, network requests or session replay; its Chrome extension attaches a screenshot to a comment, and its integrations are described by category rather than by name.
Userback is a feedback platform built around a widget, with a plan ladder that opens as a team grows: two seats free, then Team, Business and Business Plus adding AI insights, session replay, developer tools, a mobile SDK and Intercom and Zendesk integrations. MCP connectors for Claude, ChatGPT and Cursor arrive from Team. On the free plan, feedback stops being visible after seven days.
Markup.io UserbackEvery claim about Markup.io and Userback comes from each vendor's own public materials, read on 13 September 2026. Products change; check each vendor's site before deciding. Pending cells are unresearched, not zero.
The third option
Notarus is Userback's job without the ladder. Session replay, console logs, network requests and the environment are attached to every report on the free plan, with unlimited seats and 5 projects, and every panel action is an MCP tool as a shipping rule rather than a connector.
It has none of Markup.io's reach across files and none of Userback's reach into apps and support desks. Feedback is taken on a live web page only, with no PDF, video, image or Figma file, no mobile SDK, and no Intercom or Zendesk integration.
Where Markup.io bills the workspace and Userback bills the seat, Notarus bills neither, and the three amounts are on the pricing page.
No. Userback's Free Forever plan carries two seats, two projects and feedback visible for seven days. Markup.io lists only paid plans, Pro from $79 a month, Business from $499 and Enterprise on request, and its 14 day trial asks for a card. When a Markup.io trial lapses the account is restricted to the five most recent MarkUps and 10 GB rather than closed.
Userback at every published step for a small team: Team is $29 a month billed annually for five seats and five projects, and Business, where replay and developer tools begin, is $79 billed annually. Markup.io's Pro is $79 a month for one workspace. The workspace carries unlimited people, so Markup.io pulls ahead only when the review group is large.
Userback does, on its Business plan, alongside console logs and network requests listed as developer tools. Markup.io's site does not mention session replay, console logs, network requests or browser metadata; its Chrome extension attaches a screenshot to a comment.
Userback does, from its Team plan at $29 a month billed annually, with MCP connectors for Claude, ChatGPT and Cursor so an AI assistant can read the feedback. Markup.io's site does not state an MCP server or any AI feature, and this page marks both as pending rather than absent. Userback also adds AI insights and sentiment from Business. Between these two, Userback is the one that puts an assistant on the feedback today.
Userback, on its Business Plus plan, where a mobile SDK takes feedback from native apps beside the website widget; the same ladder connects Intercom and Zendesk. Markup.io's site does not state a mobile SDK, so it is marked pending here rather than ruled out, and what it names is live websites and more than thirty file types including video. Notarus has no mobile SDK and no Intercom or Zendesk integration. A team collecting feedback inside a native app is looking at Userback's Business Plus plan.
