Polar.sh Integration (Next.js + Convex)

Minimal, reusable patterns to connect Polar billing flows to Convex-backed entitlements.

When To Use

Use this skill when your app:

• Needs subscriptions, one-time purchases, or billing
• Uses Next.js App Router
• Uses Convex for backend state and access control
• Wants Polar to handle checkout, portal, payment processing, and lifecycle events

Prefer this pattern when you want billing offloaded to Polar and entitlements centralized in Convex.
