Description
Every subscription business eventually needs to handle plans, usage charges, invoices and revenue reports — Meteroid is a ready-made, open-source engine for all of that, so a SaaS team doesn't have to build its own billing system from scratch or hand it entirely to an expensive third party.
Meteroid is an open-source (AGPL-3.0, built in Rust) billing and monetization platform: subscription management, real-time usage-based metering, invoice generation, CPQ (configure-price-quote), trial/coupon management, a customer self-service portal, multiple pricing models (fixed, tiered, matrix, hybrid), and revenue analytics — all via an API-first architecture. It can be self-hosted for free or run on Meteroid's managed cloud tiers. The GitHub repo (meteroid-oss/meteroid) has roughly 785 stars.
💬 Our review
The short version: Meteroid is worth a serious look for a technical SaaS team that wants Stripe Billing-level functionality without being locked into Stripe (or paying Chargebee/Orb's enterprise pricing) — the catch is you (or your infra team) own the hosting if you go the free self-hosted route.
Compared to Stripe Billing (deeply integrated but couples you to Stripe payments), Chargebee and Orb (powerful but priced for mid-market/enterprise), and Lago (its closest open-source peer), Meteroid's real differentiator is the AGPL license plus matrix pricing support for genuinely complex pricing models. At ~785 GitHub stars it's a smaller, younger project than more established billing platforms — worth pilot-testing before betting your entire revenue pipeline on it, and self-hosting means you're responsible for uptime, security patches and scaling the billing engine yourself.
