Best alternatives to Flexprice in 2026
Charging by usage sounds simple until you actually have to build it: counting events as they happen, converting credits into dollars, handling a dozen currencies, generating tax-correct invoices, and doing all of that without double-charging anyone. Flexprice is a ready-made version of that machinery, built specifically for companies whose product is priced by how much AI or API usage a customer consumes rather than a flat monthly fee. Flexprice is an open-source billing infrastructure platform aimed at AI-native and usage-based SaaS companies: it processes usage events in real time (10,000+ events/second, under 60ms at the 99th percentile), supports usage-based, credit-based and hybrid pricing models, and automates invoice generation, multi-currency conversion and tax handling. It connects to 50+ tools including Stripe, Razorpay, Snowflake and Google SSO, and is SOC 2 Type II compliant. Because the core engine is open source, it can be self-hosted instead of run purely as a hosted SaaS. Pricing starts free (100,000 events/month, capped at $100K cumulative revenue), then Build at $500/month (1M events, $250K cap), Scale at $1,000/month (5M events, $1.2M cap), and a custom on-premise tier with SAML SSO for larger deployments.
