The billing backend for your side project.
Every developer with a side project deserves a way to monetize it without spending weeks on billing infrastructure. StackBE exists to make subscription billing as simple as adding an API call.
We combine authentication, subscription management, and entitlements into a single API so developers can focus on building products, not payment plumbing.
Building a SaaS product means solving three hard problems before you can charge your first dollar: authentication (who is this user?), billing (what have they paid for?), and entitlements (what can they access?).
Traditionally, this means integrating Stripe for payments, Auth0 or Clerk for authentication, and building custom code to connect them. You handle webhooks, sync user identities with customer records, and write entitlement logic from scratch. It works, but it takes weeks and becomes an ongoing maintenance burden.
StackBE provides all three in one API. One SDK. One integration. Authentication, billing, and entitlements work together by default because they were designed together.
Integration should take hours, not weeks. If billing is slowing you down, the tooling is wrong.
APIs, SDKs, and documentation—not drag-and-drop widgets. Built for developers who want control.
Your Stripe account, your customer relationships. We use Stripe Connect so you maintain direct control.
Flat monthly fees, not percentage of revenue. Your success shouldn't increase our take.
