For founders

Idea to preview,
fast.

Skip the sprint planning. Kaer takes your concept and ships a working, deploy-ready preview — while you're still on your first coffee.

How it works

Three steps. One afternoon.

Describe it

Type what you want to build. One sentence is enough — Kaer turns it into a running plan before you finish the thought.

≤ 4s

Watch it build

Files land, tests run, a preview URL flips live. The full build loop runs on its own — no context switching, no babysitting.

In progress

Ship from review

Open the PR, merge it, done. Kaer pushes to your repo and marks the run closed — your deploy pipeline takes it from there.

Merged · live
Every build, a preview link

Share before you commit.

Every run produces a live preview URL. Send it to your co-founder, an investor, a first user — and get real feedback on something working, not a Figma mockup.

  • A shareable URL for every branch — pr-447.kaer.dev
  • Tests, build and deploy checks visible on the PR
  • Real feedback on working software, not mockups

We shipped the entire onboarding flow in a Saturday afternoon. I described it in a Slack message, Kaer built it, and we had users on it by Sunday.Amara Osei — Co-founder, Shortloop

What will you
ship?

No team, no waiting, no sprint. Start building right now — your first preview is free.
