The plan that fits you

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 30-day free trial is once per account, not per project.

If you've already used it, selecting Pro for another project won't include the 30-day free trial.

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 > Billing & usage 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.

They are used for conversations with the AI and for creating or editing requirement docs and code. Usage varies with how complex each task is.

They are never used to deploy or run what you have built. Leaving a finished project as is does not consume tokens.

Monthly AI tokens refill to the set amount on each billing date, and any unused amount does not carry over.

Initial AI tokens and purchased AI tokens stay with you across months. Purchased AI tokens are valid for 5 years from the purchase date.

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/storage 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.

On a paid plan, no — your service keeps running.

Anything beyond your limit just rolls into next month's bill ($5 per million API calls, $1 per GB of storage).

We'll give you a heads-up as you near the limit. The hard-stop for API calls is off by default; if you'd rather keep spending in check, switch it on so calls pause once you're over.

File downloads work the other way: their hard-stop is on by default. Once you reach your monthly file download allowance, new downloads are paused until the next reset day and nothing is charged. Turn it off in settings and downloads keep going, with the overage billed at $1 per GB, rounded up to the next whole GB.

The free (Sandbox) plan has no overage charges; instead, API calls and file downloads stop at the monthly limit until the next reset day, and if the database and file storage together exceed 1GB, new uploads are refused and the deployment may be stopped. These limits cannot be lifted.

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.
