Is MarkLayer a free Superflow alternative?

Yes, for the annotation core. MarkLayer has no project, seat, or credit limits. It does not replicate Superflow's automated AI page audits or its tracker integrations.

What does Superflow's free plan include?

As of August 2026: 1 project, 1 team seat with unlimited guests, 60 AI credits a month (roughly 6 agent reviews), and 1GB storage. Paid plans start at $24/seat/month billed annually.

How do the AI features actually differ?

Superflow ships its own review agents: you spend credits and an agent posts findings on the page. MarkLayer ships an MCP server: your existing coding agent (Claude Code, Cursor, any MCP client) connects to the room, reads each annotation with its CSS selector and component name, fixes the code, and resolves the pin. One generates feedback; the other clears it.

Can both handle client review?

Yes. Superflow supports unlimited guests, with anonymous guest mode on higher tiers. MarkLayer share links open with no account for anyone, on every page.

Superflow vs MarkLayer

By Vadym Rusin · Last updated: August 2026

MarkLayer and Superflow both pin comments to live websites, and both have an AI story, pointed in opposite directions. Superflow sells built-in AI agents that review pages for you, metered by monthly credits, alongside recorded video/audio feedback and deep tracker integrations. MarkLayer is free with no meters, and its AI angle is an MCP server that puts your own coding agent inside the review room.

Bottom line

Choose MarkLayer for unlimited free annotation with your own AI coding agent working the room via MCP. Choose Superflow if you want built-in AI reviewers that audit pages for you, recorded video/audio feedback, and native Asana/ClickUp/Jira routing, priced per seat and per credit.

About Superflow

Superflow is a paid website review platform with comments pinned to live pages, video and audio recordings, and built-in AI agents that review pages on a credit system.

About MarkLayer

MarkLayer is a free, open-source web app for annotating any live webpage. Paste a URL atmarklayer.app and draw, comment, arrow, or highlight directly on the page in your browser — no install, no account, no sign-up. Share a single link and anyone can open the annotations in any browser. A free Chrome extension is available for the sites the web app cannot embed, such as pages behind a login, but it is optional and never required to view a share link. There is no paywall and no trial period.

Superflow and MarkLayer take AI in opposite directions. Superflow sells its own review agents: 10 credits per page audit, credits reset monthly. MarkLayer connects the agent you already pay for, Claude Code or Cursor, and lets it fix the annotations rather than write more of them.
