Best alternatives to Amberflo in 2026

If your product charges customers based on how much they actually use it — API calls, AI tokens, storage — someone has to count every single one of those events, in real time, across millions of requests, and turn that count into an accurate bill. Doing that counting by hand, or bolting it onto a spreadsheet, breaks the moment volume grows. Amberflo is the metering and billing engine that does the counting for you, live, so the invoice always matches what was actually used. Amberflo is a metering and monetization platform built for usage-based and AI-native businesses: it ingests usage events in real time, supports tiered, outcome-based and consumption pricing models, and layers an "AI gateway" on top that tracks cost across 1,500+ LLM models so a company can see exactly what its AI features are costing before the bill arrives. It also ships cost guards and budget alerts to stop runaway spend, plus revenue recognition automation for finance teams. Pricing runs from a 30-day free trial through a Startup plan at $99/month, Growth plans from $599 to $1,499/month, up to custom Enterprise pricing.
