Launching HUME on Product Hunt — usage metering for SaaS & AI products

HUME (Headless Usage Metering Engine) is live. If you are building usage-based SaaS & AI products — API calls, seats, tokens, agents — and do not want a billing platform to own your margins or your pricing rules, this is for you.

How it works in 3 steps

1. Send events via API or StatsD.
2. HUME prices them with your rules (JSON or Luau).
3. Get a webhook and charge through your Stripe / Adyen (or any PSP you already use).

We stay out of the money path. You keep the customer relationship and the payment stack.

The problem we kept hitting

You want to charge for API calls, seats, tokens, or “active users this month.” Off-the-shelf billing tools either:

• take a cut of revenue, or
• force pricing into their plan model and their payment stack

Founders end up with a spreadsheet, a half-finished meter, and a Stripe Dashboard archaeology project.

What HUME does

HUME is headless metering + billing logic:

• Define metrics, plans, limits, and alerts
• Ingest usage over HTTP or StatsD
• Price with JSON or programmable Luau
• Emit webhooks for invoices and thresholds
• Charge with your PSP (we stay out of the money path)

0% revenue share. You pay for real metered activity — your margins stay yours.

Who it is for

• Teams shipping usage-based SaaS or AI products (tokens, inference, agents)
• Builders who already have Stripe (or will) and do not want another locked-in billing UI
• Anyone who needs custom tiers, overage, or classify rules without rewriting the payment layer

Who it is not for

If you need a full finance department in a box (tax, multi-entity accounting, hosted customer portal as the product), buy that. HUME is the metering engine underneath.

We would love your feedback

Upvotes help, but comments help more:

1. What are you metering today?
2. What broke last time you tried usage-based billing?
3. What would make you trust a headless meter with production traffic?

Thanks for checking us out — ship something weird.
