Buildra is an AI app builder: you describe an app in your own words, an agent builds it in a sandbox you can watch, keeps talking to you until it is right, and publishes it to its own address — web apps, phone apps, backends and scripts, with the source yours to download.
Say what you want in your own words. An agent builds it in a sandbox you can watch, keeps talking to you until it is right, and publishes it to its own address.
Free gives you 5 credits a day, up to 25 a month, and up to 3 projects. No card.
Why Buildra
No template to pick and no stack to choose. The agent works out the stack from what you describe, and you can name one if you have a preference.
Every project gets a sandbox that runs the app, not just the code. It starts in seconds, sleeps when you leave and wakes when you come back, so the preview is always the real thing.
Every published project gets its own buildra.page address, and the code stays yours: sync it to GitHub or download it at any point. Nothing is locked in.
You don't need to pick a framework.
You don't need to leave the conversation to see it working.
The workspace
Buildra asks what it needs to know, then proposes a plan and changes nothing until you approve it. Then it builds while you watch, and asks again when it needs a decision. You answer in the same thread.
The preview is the app itself, running in its own sandbox, not a picture of it.

How it works
The same five stages the tower above lays down, ring by ring. You can step in at any of them; nothing ships until you say so.
01 · Plan
Say what you want in your own words. Buildra asks what it needs to know, proposes a plan, and changes nothing until you approve it.
02 · Design
It shows you design directions to choose from. Pick one, or skip and let Buildra decide. The look is set before a line of code is.
03 · Build
The runtime starts in seconds and the agent builds in a sandbox you can watch. It asks when it needs a decision, and you answer in the same thread.
04 · Preview
The preview runs the real app, not a picture of one, and updates as the agent works. Phone apps open on your own phone.
05 · Publish
One click publishes it. A failed publish leaves the live site untouched, and you can roll back to an earlier version.

What it builds
Nine apps across the four kinds the platform runs — web, phone, backend and script — in the language the person asked in. Every one of them is live on this page, not a screenshot of one.

Works with
Buildra works with what you already use. Import from GitHub or sync back to it, open phone apps on your own phone, and get a real database when the app needs one.
Paste a URL to import a repository, or sync every change back to one.
Phone apps open on a real phone while they are being built.
A D1 database when the app needs one, set up with the project.
iOS builds, and uploads to App Store Connect and Google Play, on a paid plan.
Where published projects live, one address each.
