Pay for scale, not for starting.

Paid plans need an account and sign-in; on sign-in, Spirefy checks your subscription and unlocks them. We are in beta, so these prices may change, and early users help us get them right. There is no execution metering and no API-call caps: what you pay for is how many distinct API sources live in your model, and that count is checked on your machine.

Organization features run on infrastructure you own. Accounts, roles, shared workspaces, environments, and the data behind them live on a small Go service your organization hosts and runs, so none of it sits in our cloud. You bring the server online inside your network, and your team's work never leaves it.

Plugin authors get paid, too

Publishing a plugin on the Spirefy Plugin Marketplace costs nothing. If you charge for one, you keep most of what it earns: authors start at an 80 percent revenue share, rising to 90 percent as a plugin reaches a larger audience, paid out through Stripe Connect.

Plugins do not have to be public. An organization can publish to its own members only, keeping internal tooling private and proprietary, and use org roles to decide who is allowed to publish, update, or pull a plugin on its behalf. The technology page covers how signing and distribution work.

Questions

What does it cost to start?

Download Spirefy Studio and bring your work into one model: up to two API sources, inspected, linted, designed into workflows, generated from, and shared in real time on your network. It is a real working tool, not a trial. A small estate fits in the app you download; you pay us when it outgrows two sources, when you want the built-in AI model, or when your organization needs to govern many projects at once.

We also know the feeling. Oh good, another app that wants a sign-up and a subscription. We get that fatigue too, on our own bills. So we kept it honest: work in the app on a small estate, and when your team needs more, it is per person, with no usage meters and no counting your API calls. You pay when the work grows, not for the privilege of starting.

The plain truth is that servers, cloud, and salaries arrive every month. If Spirefy Studio earns a place in your week, the amount we ask, plus the few minutes to set up a payment account once, goes straight into keeping the work going and making it better. We think that is a fair trade, and that the price holds up well next to everything else you would otherwise stitch together.

Do I have to pay for AI?

Only if you want it. The built-in AI is included with the Team and Enterprise plans, and a $5 a month add-on on the app you download. Some of our earliest beta users have it free for life. Everything else in the app works without it.

The model we ship is not a generic chatbot. It is fine-tuned to understand the Spirefy unified model, so it works on your APIs directly in that shape: proposing and applying changes in real time, suggesting fixes as you work, and helping with governance and getting an API ready for machines to consume. It runs on your machine, so your APIs never leave it.

How does Spirefy compare to other tools?

Postman, Bruno, Jentic, and others are very good at what they do, and we genuinely encourage you to weigh them against Spirefy Studio and pick what fits your work. Pointing you toward the competition may sound odd, but we would rather you use the right tool than the wrong one. If Spirefy Studio is not it, we do not want to waste your time or your money. If we fall short, please share feedback so we might earn your business.

If you have the developer chops, you can go a step further than choosing a tool: build your own plugin. Keep it internal and proprietary to your organization, or publish it on the Spirefy Plugin Marketplace and earn from it. Authors start at an 80 percent revenue share, rising to 90 percent as a plugin reaches a larger audience.
