Best Credyt alternatives for AI billing

Credyt is purpose-built real-time billing infrastructure for AI products, built around pre-authorization and prepaid wallets. Teams evaluate alternatives when they need invoice-based subscription billing with global payment processing, require enterprise contract management with ASC 606 revenue recognition, or want entitlement orchestration for complex plan tiers and pricing experiments.

These two alternatives are shortlisted because they address the two most common reasons teams evaluate Credyt alternatives: entitlement-first billing and open-source transparency. Stigg is the right evaluation if your product needs sophisticated plan versioning, pricing experiments, and feature gating above an existing payment processor (Stripe, Zuora) rather than a new billing infrastructure layer. Flexprice addresses the open-source use case: both Flexprice and Credyt treat wallets as first-class infrastructure, but Flexprice publishes its code under AGPLv3 and supports self-hosting on Docker Compose or your own cloud. The billing models are similar (both support real-time wallet debits), but Flexprice debits via invoice payment rather than atomically per event. Teams choosing between these three usually know whether they need pre-authorization before inference runs (Credyt), entitlement management above an existing system (Stigg), or an open-source wallet platform they can audit and deploy themselves (Flexprice).
