Superflow vs MarkLayer: a free Superflow alternative

By Dean Rusin · Last updated: October 2026

MarkLayer and Superflow both pin comments to live websites, and both have an AI story, pointed in opposite directions. Superflow sells its own review agents: pay per site or spend credits, and a built-in AI audits the page for broken links, accessibility issues, or copy problems without a human driving it. MarkLayer has no built-in reviewer at all. Instead, its MCP server opens the annotation room to whatever coding agent you already run, so the agent that reads a MarkLayer pin is the same one already sitting in your editor.

That's an architectural difference as well as a pricing one. Superflow's agent generates findings, more things flagged on the page, metered per site or by credits. MarkLayer's agent connection is built to close findings: an agent watching a room can read an annotation's CSS selector and component name, make the actual code fix, and resolve the pin itself, with the status update visible live to everyone else in the room. One workflow adds work to a page; the other removes it.

Which one earns its keep depends on where a team's bottleneck actually is. A team that struggles to catch problems in the first place, thin QA coverage, no one auditing for accessibility, benefits from Superflow's automated reviewer flagging things nobody asked it to look for. A team already drowning in flagged annotations, where the backlog is the problem, gets more from MarkLayer's model: point an agent at the room and let it clear the queue.

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: $14 a site, or credits per scan (5 for a small site, as of October 2026). MarkLayer connects the agent you already pay for, Claude Code or Cursor, and lets it fix the annotations rather than write more of them.

Frequently asked questions

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 two-way tracker integrations.
What does Superflow's free plan include?
As of October 2026 the Starter plan is $0 and includes one small-site scan. Growth is $29/seat/month, or $24 billed yearly, with 2 projects; Scale is $34/seat/month, or $28 yearly, with 4 projects. The page lists a 10-day free trial and 30 signup credits, and does not say which plans they apply to. It prints no seat limit for Starter.
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 prices per seat and says client reviewers need no seat because they review over a link. MarkLayer share links open with no account for anyone, on every page.
How does Superflow charge for AI reviews?
As of October 2026, two ways. Bulk is $14 per site per month for unlimited reviews and monitoring. Or you spend credits per scan: 1 for a single page, 5 for a small site (up to 30 pages), 10 for a medium one, 15 for a large one, 30 for an extra-large one, and 1 for a rescan. Credit packs run $10 for 25 credits up to $49 for 145. MarkLayer's MCP connection has no credit meter of any kind; the cost, if any, is whatever you already pay for the coding agent itself (Claude Code, Cursor, or another MCP client), not a per-review charge from MarkLayer.
