Bottom line: MarkLayer is the closest free, no-sign-up replacement for Markup.io if all you need is visual feedback on live pages. PageProofer, BugHerd, and Pastel are paid options that add agency workflow features. Hypothesis is free but text-only.

Best for: Anyone who wants the core Markup.io use case (live webpage feedback) without sign-up or fees.
Visual feedback on staging sites with sticky-note style comments. Has a free trial; paid plans for teams.
Best for: Teams already comfortable with a paid SaaS workflow.
Visual bug tracker with a Kanban board and integrations into Jira, GitHub, Trello, and Asana. Paid only.
Best for: Teams that need full bug-tracking workflow, not just feedback.

Best for: Agencies running structured client review cycles.
