Where Kumiau fits
From a prototype on your machine to shipped, in one place.
Kumiau is the easy place to get a prototype live and shareable — no hosting to set up, no deploy pipeline to configure. From there, it gets feedback that sticks — pinned to the exact spot, correctly attached to the exact revision — and a connected coding agent turns that feedback into the next shipped version.
Where you already are
From zero to shareable, then to shipped.
- Instead of setting up hosting yourself
A shareable link in seconds, not a deploy pipeline.
Upload a prototype and it's instantly a real, running link — no build config, no hosting account to spin up, no zip file to email around. Choose who can view it or comment, by a link or a verified account, and change that anytime.
- Coming from Figma
See it live, not just designed.
Once a prototype is real and running, feedback belongs there too. Reviewers pin comments to the exact spot on the live experience — the actual interaction, the actual state — in a thread you resolve together.
- Instead of a Loom recording
Feedback that sticks, not a video to re-scrub.
Every pin stays exactly where it was left, on the exact revision it describes. Nobody has to scrub through a recording to find the one comment that mattered.
- Alongside a Vercel preview
Control who sees it, and feedback that keeps up.
Grant view or comment access to exactly the right people, and watch every comment thread stay correctly attached to the revision it was left on as the prototype evolves through new versions.
What only Kumiau does
A coding agent that ships the fix.
Connect an MCP-compatible coding agent and it reads exactly what reviewers pinned and publishes the next revision itself — the step every other tool in this loop leaves as a manual hand-off. Kumiau closes it.
Questions
Good to know.
Is Kumiau a Figma alternative?
Kumiau is where a prototype becomes a reviewable, running experience: reviewers pin feedback exactly where it applies, on the real thing, and a connected coding agent can ship the fix directly.
Can I use Kumiau instead of Loom?
Kumiau turns feedback into something structured and lasting — pinned to an exact spot on the prototype, in a thread you resolve together, still there the next time anyone opens it.
Does Kumiau work with Vercel preview deployments?
Kumiau adds per-person sharing control and feedback that survives every new revision on top of your hosted prototype, plus the MCP connection that lets your coding agent act on it directly.
What does Kumiau do that nothing else does?
Connects a coding agent directly to your feedback loop: it reads exactly what reviewers pinned and publishes the next revision itself — no copying comments into a chat window.
