· SUPERFLOW VS MARKUP.IO · THE AI QA REVIEWER FOR AGENCIES
Markup.io is a feedback tool. Superflow is a feedback tool + a team.
The team is AI agents, built from your QA checklist. They check every site change and pin what they find. Your team decides. Your client approves from a link.
If your agency reviews client sites in Markup.io, this page is for you.
If flat-price, link-based visual commenting on websites and files, with a simple statuses and sign-off flow, is all you need, Markup.io is a fine tool. Stay.

The collaborative platform for modern web teams.
Who checks the site
Markup.io was built before AI could check a site.
Verdict
A MarkUp is a record of what a person already caught. That's the part Superflow removes.
Superflow
Superflow- Agents run your checklist. Every change, desktop and mobile.
- Findings land as pinned comments, rationale attached.
Markup.io
Markup.io- A person checks it. Nothing checks the site automatically.
- No AI features found on markup.io, July 2026.
(verified July 2026)
How the client says yes
Feedback is easy to collect. A yes is harder.
Verdict
Markup.io's Sign off flow is real and per-reviewer, a genuine strength. Superflow's gate goes further: your team decides first, then the client approves, from their phone, no account.
Superflow
- Multi-step review flows: agents check, your team gates, then the client.
- Your client opens a link and taps Approve. No account, no login, no app, from their phone.
Markup.io
- Guests comment free from a link with no account.
- Statuses plus a per-reviewer Sign off flow: Open for review, Editing content, On hold, Completed. Only Admins and owners set status.
(verified July 2026)
Where you review
Comments on a copy are comments about the past.
Verdict
Markup.io reviews the live URL through a proxy render; Superflow reviews the site itself, behind logins and SSO, no extension.
Superflow
- Superflow lives on the site itself: passwords, Okta, SSO, no extension needed, guests included.
- Findings tagged by device.
Markup.io
- Renders the live URL through its own proxy, inside an iFrame.
- Login-gated or iFrame-blocking sites can break, and may need the Chrome extension or a temporary auth change by your dev team.
(verified July 2026)
What stays private
Your team needs somewhere to disagree.
Verdict
Renders as a difference only if the Markup.io side resolves to one.
Superflow
- Internal-only notes your team sees and the client never does.
- The debate stays private; the client sees one settled answer.
Markup.io
- Private MarkUps make a whole MarkUp private, a different concept.
- Internal or private comments the client cannot see: not yet verified.
What gets captured
Both tools pin. The difference is what gets attached without asking.
Verdict
Pinning is even. Capture is the gap: Markup.io's auto-screenshot rides the Chrome extension. Superflow's attaches itself, no extension.
Superflow
- Element and text pins, area comments.
- A screenshot attaches to every comment automatically.
- Recordings: screen, video, voice, from the toolbar.
Markup.io
- Chrome extension auto-captures a screenshot on every comment or pin.
- Auto screenshots without the extension: not yet verified.
- Native video or screen recording: not yet verified. Loom integration attaches video.
(verified July 2026 except where noted)
What it remembers
Boards hold tasks. They don't accumulate a client.
Verdict
The tenth project should not start like the first.
Superflow
- Brand rules and past decisions, learned once, fed to the agents next project.
Markup.io
- No per-client memory or knowledge concept found: not yet verified.
How it fits your stack
The fix still has to ship.
Verdict
Markup.io has native Teams and Loom; Superflow doesn't today. If Teams or Loom is your spine, weigh that honestly. Markup.io's sync runs outbound only; Superflow's runs two-way.
Superflow
- Custom statuses, client gates, kanban.
- Two-way Asana, Monday, ClickUp. Slack built in.
Markup.io
- Workspaces, Folders, and Statuses on a dashboard. No kanban found.
- Native Slack, Microsoft Teams, Loom, and Zapier, plus a public API with webhooks.
- No native two-way sync: outbound only, via Zapier, the API, or webhooks.
