How we chose these Stripe Billing alternatives

We looked for open-source tools that cover parts of Stripe Billing: subscriptions, usage metering, invoicing, and payment handling. We verified each project's license, recent activity, stars, and self-hosting in its repository. Stripe Billing is a layer on top of Stripe's payments, while most alternatives either sit on top of Stripe or other processors, or replace the billing logic, and none of them is a payment processor itself, so we note where each fits. See our methodology for the full criteria.

Important: these are billing layers, not payment processors

None of these moves money by itself. Lago, Flexprice, OpenMeter, Meteroid, UniBee, Paymenter, and Autumn manage plans, usage, and invoices and then charge through processors such as Stripe or PayPal. Hyperswitch routes payments across many processors. Formance provides a ledger and financial workflows, and Crater is a simple invoicing app.

Usage-based billing options

Lago, Flexprice, OpenMeter, Meteroid, and Autumn target usage-based and hybrid pricing for SaaS, AI, and API companies, with real-time metering, credits, and flexible plans. OpenMeter focuses on metering and usage limits, while Lago and Meteroid also handle invoicing end to end.

License details

Hyperswitch, OpenMeter, and Autumn are Apache-2.0, Paymenter is MIT, and Formance's ledger is MIT. Lago, Meteroid, UniBee, and Crater are AGPL-3.0, and Flexprice is AGPL-3.0 with a commercial Enterprise directory. Formance's wider stack keeps an ee directory under an Enterprise license.

Self-hosting and cost

All can be self-hosted, and most also offer managed cloud plans. Autumn can be self-hosted but depends on several services, so the team points to its hosted version for most users. Paymenter offers cloud deployment from $5 per month, and Autumn's hosted plan is free until a revenue threshold.

Maintenance status

Crater has had no commits since August 2024, and UniBee's last commit was in February 2026. Hyperswitch, Lago, Flexprice, Autumn, Paymenter, OpenMeter, Meteroid, and Formance were updated within days or weeks of this update.

Why look for a Stripe Billing alternative?

Stripe Billing is a proprietary service that adds a percentage fee on top of payment processing and is tied to Stripe's platform. Open-source billing tools let you own your pricing logic, run usage-based and hybrid pricing models, connect multiple payment processors, and avoid billing fees, at the cost of integrating and operating the system and handling payment compliance with your processors.
