## What it is
Flexprice is an open-source usage-based pricing and billing platform for developers, offering real-time usage metering, credits and wallets, pricing experiments, and invoicing. It can be deployed in the cloud or self-hosted and integrates with payment and business tools like Stripe.

## Use cases
- meter API or AI product usage in real time
- implement usage-based or hybrid pricing for a SaaS
- manage prepaid credits and customer wallets
- generate invoices and sync them to Stripe
- control feature access based on subscription entitlements
- self-host billing infrastructure instead of building it in-house

## When to choose
- you need usage-based, credit-based, or hybrid billing without building metering from scratch
- you want an open-source, self-hostable billing engine with a no-code UI
- your AI-native or SaaS product needs real-time metering and entitlement enforcement

## When to avoid
- you only need simple flat-rate recurring subscriptions with no usage metering
- you require a fully managed vendor with enterprise SLAs and cannot operate infrastructure
- your product is not commercial and has no monetization needs
