Ship your app to the cloud.
Without the cloud part.
Connect a repo and Koo builds, deploys, and scales it for you. Databases, domains, and metrics included — no YAML required.
A whole platform, none of the busywork
Koo handles the infrastructure so you can stay in your editor. Ship the first version tonight and scale it when people show up.
Deploy in seconds
Connect a repo and Koo builds, ships, and hands you a live URL. No Dockerfile, no YAML, no ops rotation.
Every push, deployed
Turn on auto-deploy and every push to your connected branch ships on its own. Roll back to any previous deploy in one click.
Batteries included
Postgres, Redis, cron jobs, and persistent volumes. Add one from the console and it's wired into your app.
Autoscaling that just works
Koo watches traffic and adds capacity before your users notice. Scales to zero while your project sleeps.
Built for vibe coding
Ship whatever your AI wrote, then watch logs and metrics stream in the console the moment something needs a fix.
Safe by default
Free TLS, private networking, and encrypted variables with audited reveal on every project. Nothing to configure.
Three steps to live
No tutorials to finish first. This is the whole flow.
Link GitHub and pick a branch. Koo detects your framework automatically — Next, Django, Rails, Bun, whatever.
We build the app, provision what it needs, and roll it out with zero downtime. Watch it stream in the console.
Get a koo.app URL instantly, add a custom domain, and let people try your app, vote, and leave comments.
Build with Koo, your way
Reach for the console, a typed SDK, or hand the keys to your agent. Everything Koo does is scriptable.
CLI
Deploy, tail logs, and open a shell from your terminal. The fastest way to ship without leaving your editor.
$ koo upSDKs
Typed clients for TypeScript and Go. Script deploys, wire Koo into CI, or build something new on the API.
$ npm i @koo-io/sdk$ go get github.com/koo-io/koo-goBuilt for agents
An MCP server plus ready-made skills, so your agent can deploy, read logs, roll back, and scale on Koo — safely.
See what people are shipping
Every public app gets its own page where the community can try it, vote, and leave feedback.
Your app is one push away
Start free, no credit card. Deploy something tonight and see who shows up.
