Frequently Asked Questions
Can I use Holdify with Firebase?
Absolutely! Use Firebase for your app backend and Holdify for API key management. They work great together.
How do Firebase API keys differ from Holdify?
Firebase API keys are project credentials for accessing Firebase services. Holdify provides full API key management for your own APIs with per-key limits, analytics, and subscription sync.
Which is better for monetizing my API?
Holdify is purpose-built for API monetization with native Polar integration. Firebase doesn't have built-in support for subscription-based API access control.
