Ziflow is a proofing platform; you route campaign assets through it for approval. Couac is narrower. It's a Ziflow alternative for website feedback for the moment the question stops being which visual to sign off and becomes which bug to fix. So two jobs, not the same one.
Ziflow shines when dozens of files wait for a clean approval and a final sign-off. But the day a button stops working in production, you don't want an approval cycle; you want the capture, the DOM, the console and the network sitting in a ticket your developer opens straight away.
| Criterion | Ziflow | Couac |
|---|---|---|
| What gets reported | Assets to approve: design, video, PDF, banners, emails, 1200+ file types. The review is about the content, not the technical environment. | A bug on a web page. Annotated capture, DOM selector of the clicked element, console, network requests, device: everything you need to reproduce it. |
| What happens next | An approval workflow: stages, reminders, compared versions, final decision and sign-off. Built to push a validation forward. | A Kanban board where the ticket lives, changes status and gets comments; plus a REST API, signed webhooks and a native MCP server so agents can read and act. |
| The technical side of the widget | A browser plug-in lets reviewers comment on a live site or an HTML5 banner. But no console, network or device context is attached to the comment. | A JS widget you drop on the site; it grabs the technical context on its own, without the reporter ever knowing what a console is. |
On Ziflow, a comment tells you what's wrong with the asset. But a developer needs more: the exact URL, the targeted element, the console error, the failed network call, the device. Couac sticks all of that to the ticket; your developer opens it and fixes it without guessing.
Ziflow pulls your reviewers into its approval platform. Couac does the opposite: the client clicks the widget and that's it. And to follow up, you send a board shared by magic link, no signup, no onboarding to explain.
Ziflow's strength is approval routing. Couac targets the developer end of the chain: signed webhooks into your CI, a REST API for your scripts, a native MCP server so an agent can read a ticket, comment and move a status. The history stays machine-usable.
The comparison pages link to each other, then point to the MCP docs, REST API docs and pricing. Readers find the next page; search engines see how the topic fits together.
No, and that's on purpose. Ziflow is built for multi-format proofing and asset sign-off; if your need is getting a campaign approved, keep Ziflow. Couac only handles one thing: bugs and feedback on your web pages.
Alongside, in most cases. You approve your visuals in Ziflow; you surface the site's technical bugs with Couac. Two different stages of the project, so two tools that don't step on each other.
That's right. The Ziflow plug-in is there to drop comments on a site or a banner. The Couac widget attaches the console trace, network requests, device and DOM selector to the ticket; that's what saves the developer time on the other end.

Request access, install the widget on a pilot project, then check whether the context is enough to fix the issue without asking for three more screenshots.
