Why ApisKit?
Clean, battle-tested architecture
Hexagonal architecture: core, ports and adapters keep your business logic separate from Next.js, Firebase, Stripe and the interface.
The foundation is set up so you can change and adapt pieces without mixing everything from the start.
Accounts and sessions ready
Sign-up, sign-in, password recovery, email verification, sessions and protected routes.
You do not just get a login screen. You get the account flow already wired.
Payments and credits built in
Checkout, webhooks and a credit system with a movement ledger.
Because charging does not end when someone clicks the pay button. You also have to control what happens next.
Admin dashboard
Manage users, support and credits from a separate, role-protected panel.
Your users need an app. You need a place to run it from.
Built-in support
Ticket system with attachments, replies and statuses, connected to the admin panel.
The user writes from their account. You reply from yours.
Verifiers included
Static and runtime validation: type checking, linting, i18n and duplication control built into the pipeline.
They do not make software infallible. They keep certain classes of errors from depending on manual review alone.
Before and after
You can build these pieces by hand or ask an AI to generate them. Either way, the integration, the review and everything that happens when the pieces start working together still remain. ApisKit lets you start after that repeated work.
