Holdify bridges your payment provider and your API. The problem: You use Stripe for billing, but who handles API access? Most teams build webhooks and sync logic from scratch. The solution: When someone subscribes, Holdify automatically creates their API key with correct limits. Upgrades, downgrades, cancellations - all synced instantly. Features: • API key generation & verification • Rate limiting per customer • Native Polar integration • Usage analytics Free tier: 150K requests/month

Hey 👋 I built Holdify because I kept running into the same problem: payment providers handle billing great, but who handles API access? Every time I built a paid API, I had to: • Set up webhook handlers for subscription events • Build logic to create/revoke keys on plan changes • Implement rate limiting from scratch • Handle edge cases like failed payments It was weeks of work that had nothing to do with my actual product. So I built Holdify - connect your Polar or Stripe account once, and API access syncs automatically. New subscription? Key created. Upgrade? Limits increase. Cancel? Access revoked. Currently live with native Polar integration, Stripe coming soon. Would love your feedback! What features would make this more useful for your projects? 🔗 Try it free: https://holdify.io
