Pricing
We’ve broken the mould. Every plan is baseline subscription plus metered. A fixed monthly fee for your tier, then you only pay for what you use. First the build. Then servers, database, compute and payments once you’re live. Going from 10 customers to 100 won’t send your bill through the roof. Your SF account balance pays as you go. Tiers unlock more as you grow. Startup to get going. Venture for established businesses. Enterprise for scale, security and support.
Usage is charged on top of the plan. Rates can differ by plan — choose one to see its rates.

The tiers
Same factory, same journey. What changes is How much you unlock as you grow. Each tier adds more features, scale and support, so you only pay for what your stage needs.
For founders building their first product. One mission statement in, to your first £, €, $ and ¥.
For established businesses launching their next product. Replatform, add adjacent and downstream products, or build solutions for clients.
For larger groups that need enterprise grade scale, security and support. Spec Builder turns your PRDs into products, fast.
Evaluating for Enterprise? Read the Enterprise overview for security, compliance and scalability, all in one place.
FULL TRANSPARENCY
Nothing is hidden. Every cent is shown against what it built: your product, your tech stack, your business stack. So you’re always in full control: You also share our infrastructure, so there are no separate services to find, buy and stitch together. Most software subscriptions are a black box. This one keeps receipts. How it works.
