FAQ

With BackendX, plans are managed per project (backend), not per account.

For example, if you run a shopping mall and a booking app, you can apply a separate plan to each.

Every project requires a different scale — keep small projects lightweight and allocate more resources to larger ones.

No — the first month free is once per account, not per project.

If you've already used it, selecting Pro for another project won't include the free first month.

On the day the free period ends, $129 is charged automatically to your payment method and renews on the same day each month. You can check the next billing date anytime in Project settings > Plan.

If you do not want to continue, cancel anytime before the free period ends. You can keep using the plan through the end of the trial, and no further charge will be made.

Project settings > Plan > Cancel plan lets you cancel anytime. Cancel before the next billing date to avoid the next charge.

Canceling does not shorten your current access. During a free trial, access continues through the trial end date; on a paid plan, it continues through the end of the paid month.

A requirement change is any update to your backend's features or structure — like adding a data field or reworking how something behaves.

Because the AI regenerates your code each time, every plan includes a set number per month (1 on Starter, 3 on Pro, 5 on Business).

Need more? Add them for $25 each, or save with a 10-pack for $200.

It really comes down to two questions.

Want to grab the code and Docker image and run things yourself? Go with Builder. Want BackendX to handle deployment too? Pick Starter, Pro, or Business.

And if you're running something serious that needs generous API/DB capacity and backups, we'd suggest Pro or above.

You can try the whole flow, from generating code to deploying it.

Deployments stay up for up to 60 minutes total per project and spin down automatically after 10 minutes with no API requests — they come right back the moment a new request hits.

You also get up to 0.1M API calls a month, though backups aren't included.

No — it keeps running.

Anything beyond your limit just rolls into next month's bill ($5 per million API calls, $0.50 per GB of DB).

We'll give you a heads-up as you near the limit, and if you'd rather keep spending in check, you can switch on a hard-stop for API calls so they pause once you're over.

Just add collaborators (seats) to your project.

Pro and Business both include 2 seats, then $19/month per extra seat on Pro and $29/month per extra seat on Business.
