About
Problem: Stripe is for payments, but billing is a logic nightmare. Most of us start with Stripe and realize we just inherited a second job: building a complex state machine for credits, usage, and subscriptions. If you're building in 2026, you shouldn't be debugging webhook race conditions or worrying about EU-VAT compliance.
The Solution: Commet, we built Commet to be the "Source of Truth" for your SaaS. It’s a Merchant of Record (MoR) with a built-in deterministic billing engine.
Why devs love it:
No Webhook Hell: Our engine handles the state. Your app just asks our API: "Can this user do X?" and gets a real-time boolean.
Tax Compliance on Autopilot: We are the legal seller. We handle global taxes, invoices, and compliance so you don't have to hire an accountant in 20 countries.
Built for AI & Usage: Perfect for credit-based models. Stop losing margins to "heavy" users.
LLM-Friendly: Our logic is so clean that Cursor or Claude won't hallucinate your billing implementation.
The Story: I got tired of building the same billing glue-code for every project. I wanted something where I could just define my pricing and start charging. That’s Commet.
