Describe it. Build it. Ship it.
The AI app builder that runs your app, not just the code.
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
One sentence.
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.
One runtime.
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.
One address.
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.
Software used to start with a stack. Now it starts with a sentence.
You don't need to pick a framework.
You don't need to leave the conversation to see it working.
The workspace
The conversation on the left. The running app on the right.
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 worksA site for a small coffee roastery that roasts on Tuesdays and delivers on Thursdays
Plan approved4 of 4
- A one-page site with the roast calendar
- This week's beans, with tasting notes
- An order form for Thursday delivery
- Opening hours and a way to get in touch
Building the order form now. Should it ask for a delivery window, or just an address?

How it works
Five layers, and you watch every one
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 it, then approve the 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
Pick the direction
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
Watch it get built
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
Use it while it grows
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
Put it live, keep the code
One click publishes it. A failed publish leaves the live site untouched, and you can roll back to an earlier version.

What it builds
One sentence made each of these
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
Your repo, your phone, your address
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.
- GitHub
Paste a URL to import a repository, or sync every change back to one.
- Expo
Phone apps open on a real phone while they are being built.
- Cloudflare D1
A D1 database when the app needs one, set up with the project.
- App Store
iOS builds, and uploads to App Store Connect and Google Play, on a paid plan.
- buildra.page
Where published projects live, one address each.
Stacks
Build it in the stack you know
Name a stack and Buildra builds in it. Say nothing and it picks one for you. Web apps, games and APIs publish to a live link on Buildra Hosting.
