Commet

Hey Hunters!

I’ve spent the last 5 years building products and working in payments. And I know every builder wants the same thing: launch fast.

Last year, I watched a friend’s startup spend six weeks building billing logic instead of shipping features. They needed usage tracking, credit systems, and EU tax compliance. Stripe gave them the payment rails, but none of the logic on top.

That’s why we built Commet.

We are

• Consumption-first: Built for credits, usage, and balance-based models — not just flat subscriptions

• Single source of truth: Your app asks “can this user do X?” and gets a real-time answer

• Merchant of record: We handle global taxes so you don’t need lawyers in 30 countries

• No webhook hell: Deterministic state instead of eventual consistency

Who it’s for

• AI tools charging per generation

• SaaS with usage-based pricing

• B2B platforms with seat + metered models

• Teams tired of rebuilding billing from scratch

Try it

Head to sandbox.commet.co and create a test plan in under 5 minutes. You can prompt your pricing or paste a screenshot of your pricing page and generate plans automatically.

Our SDK works with Node and Next.js, and we just shipped a Better Auth plugin.

What we’re working on

• More payment methods

• Data extraction and visualization.

• MCP so agents can operate on Commet (refunds, plan creation, subscription updates)

• Open-sourcing the billing core

Reach out, ask anything, or send us feedback to our X account o directly to me. We’d love it.
We grow if you grow.

LONG Commet

Congrats on the launch!!!
