Amberflo
Real-time usage metering and billing platform that tracks AI/API costs and turns them into invoices, budgets and cost controls.
🔗 Visit Amberflo
Description
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.
💬 Our review
The short version: Amberflo is a solid pick for a company whose product is priced by usage and whose finance team is tired of reconciling metering data by hand — the real-time AI cost tracking across 1,500+ models is the feature that stands out from older usage-billing tools.
The honest trade-off is that this is a crowded, well-funded category: Stripe Billing now covers a lot of the same usage-based ground for teams already on Stripe, Orb targets the same audience with a similar real-time-metering pitch, and Amberflo's own AI-cost-tracking angle is the newest and least proven part of the product next to its more mature metering core. For a team specifically drowning in per-token AI cost visibility rather than generic usage billing, Amberflo's AI gateway is a genuine differentiator; for a team just starting usage-based billing and already inside the Stripe ecosystem, Stripe Billing is the lower-friction first stop.

❓ Frequently asked questions
- What is usage-based metering and why can't I just track it in a spreadsheet?
- Usage-based metering means counting billable events (API calls, tokens, storage) in real time, at whatever volume your product runs at. Once volume grows past a few thousand events, a spreadsheet or manual export can't keep up accurately or in real time — that's the gap Amberflo fills.
- Can Amberflo track AI/LLM costs specifically?
- Yes — its AI gateway tracks usage and cost across 1,500+ LLM models, so a team can see AI spend per feature or customer before the bill arrives, not after.
- Does Amberflo replace my payment processor?
- No — Amberflo meters usage and calculates what's owed; it typically integrates with a payment processor like Stripe to actually collect the money.
- Is Amberflo open source or self-hostable?
- No, Amberflo is a closed-source, hosted SaaS platform with no self-hosted option.
- Is it worth the money compared to alternatives?
- At $99-$1,499+/month, Amberflo sits above Stripe Billing's usage add-on (bundled if you're already on Stripe) but below fully custom enterprise billing builds. If your core need is AI/LLM cost visibility specifically, the built-in gateway can be worth the premium; for generic usage billing on top of an existing Stripe setup, Stripe Billing is usually cheaper to start.
- Which tool should you pick for your case?
- Need deep, real-time AI/LLM cost tracking: Amberflo. Already fully on Stripe for payments: Stripe Billing's usage features. Want an open-source, self-hostable billing engine: Lago. Need a real-time metering engine with flexible rate cards at scale: Orb.
