A Subscription SaaS Starter You Can Ship This Week
Subscriptions need plans, upgrades, scheduled downgrades, webhook sync and tiered access — the boring 80% before any product value. It is already built and wired.
What is already wired
Monthly and yearly plans through Stripe Checkout, with the billing portal for self-serve changes.
Immediate upgrades and scheduled downgrades, kept in sync with Stripe via webhooks — Stripe stays the source of truth for status.
Routes are gated by tier, so higher plans unlock more of the app with one access check.
A polished left-sidebar member area and a separate admin app to run the business.
This is the flagship use case, and it is honest about the hard parts: webhook idempotency, scheduled plan changes, and treating Stripe as the single source of truth for subscription status rather than guessing locally. If your product also meters usage, pair it with the Stripe credits & usage billing engine — they share the same codebase.
Switch plans and watch access flip.
The subscription demo is fully interactive — no card, nothing saved.
