01“So, what does it actually do?”

A simple conversation
builds your backend

Describe the service you want in chat. BackendX asks what it needs to know,
then builds the spec, APIs, database, and deployment in order.

Pilates booking app
I want a booking app for my pilates studio: sign-up, class booking, and payments.
BackendXGreat. I've designed it around members, a class schedule, bookings, and payments. How should refunds work when a booking is cancelled?

07“Just a few more questions”

Honest answers
to what you're wondering

Isn't an AI frontend tool enough on its own?

It can build the screens. But a real service needs member data, payment processing, data rules, and server operations. BackendX takes that part, from the spec to deployment and operations, and gives you a prompt to connect the screens you built.

Does it build the frontend too?

No. BackendX builds only the backend. When it's done, you get API docs and a prompt for building screens. Screens built by an AI that reads well-organized API docs match the real data far better than ones you explain by hand.

Can I use it with zero coding knowledge?

Yes. Describe the app in plain words, and BackendX asks questions, organizes the features, writes the code, and deploys the server. You never touch a terminal or server settings.

How far can I go for free?

On the Sandbox plan you can try everything through code generation and deployment. Deployments stay up for a cumulative 60 minutes per project; keeping one running needs a paid plan.

Can I take the generated code with me?

Yes. You can edit the source code or move it to another server, so you can keep going if you work with a developer later. Source code comes with Pro, Business, and Builder; Docker images from Starter and up.

What does per-project pricing mean?

You pick a plan for each backend (project), not for your account. Running a store and a booking app together? Give each the plan that fits. Small projects stay light, big ones get room.

What changes when I connect over MCP?

Connect BackendX to the AI tool you already use once, and it reads your project's docs and APIs directly, with no copying prompts around. It works for building screens and for changing or checking features too.

What happens if the server has a problem?

BackendX keeps watching server status and errors and explains what happened in plain words on the dashboard. You also get a heads-up when usage approaches the limit.
