Why we moved from monthly pricing to a credit balance

Diploi's new billing system is live. We moved from monthly pay-per-use pricing to a single credit balance that covers everything, deployments and AI usage alike.

The short version of why: for hosting, an end-of-month bill is the norm (think AWS), and when usage is stable it's convenient. AI token usage usually isn't stable. One developer might spend a few cents a day on the built-in AI gateway; another might spend a hundred euros an hour. We needed a model that works from cents per month to thousands per month, where you always know what you're spending.

A prepaid balance does that. Your ceiling is whatever you've put in. There's no invoice at the end of the month, so there's no surprise on it either.

So we made everything run off one balance.

What changed

  • All billing runs through a single account balance. You add balance manually or enable auto top-up.
  • You can pick a monthly plan for extra benefits, or stay on pay-as-you-go.
  • AI usage through our built-in gateway is deducted from that same balance. We support for all the newest models.

Existing paying users received initial credits, so nothing broke when the switch happened.

New plans: Pay-as-you-go, Pro or Ultra

With Pay-as-you-go (0 €/month), you add only the balance you plan to use and top it up whenever you need to.

If you choose a monthly plan instead, you get a fixed balance added to your account every month:

  • Pro, 20 €/month — the full amount is credited to your balance, and you get a higher daily AI usage limit plus 5% off AI usage through Diploi.
  • Ultra, 100 €/month — the full amount is credited to your balance, there is no daily AI usage limit, and you get 10% off AI usage through Diploi.

Unused credits carry over to the next month, so your balance never expires. That last part mattered to us: "use it or lose it" credits are a way of quietly charging people for nothing, and we didn't want to build that in.

New billing insights page

You can now see a detailed breakdown of your deployments' running costs and (almost) real-time AI usage in one place, along with all the billing settings you now have access to in Diploi.

The breakdown shows your current and previous months' usage together with your balance top-up details.

Customizable top-up settings

The obvious risk with a balance-based model is running dry mid-deploy. To avoid unexpected shutdowns when you run out of credits, you can set an automatic top-up that triggers whenever your balance falls below a threshold.

If you prefer to add credits manually, the "Add balance" option is available on your account's billing page.

Diploi is a platform that abstracts away infrastructure, CI/CD and dev environments, so you (and your agents) can build, host and run full-stack apps entirely in the cloud with zero local setup.
