Three steps. One afternoon.

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.

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.

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.
What will you
ship?
No team, no waiting, no sprint. Start building right now — your first preview is free.
