Polar is a developer-focused billing platform for accepting payments, managing subscriptions, and issuing invoices. It combines payment links, APIs, webhooks, and self-hosting options for indie software projects. The platform aims to make billing simpler than larger payment providers.
Polar offers a free hosted plan covering unlimited products, subscribers, invoices, payments, payment links, API access, basic webhooks, and email support. Paid Pro and Business tiers add custom domains, extra team seats, analytics, priority support, and higher usage limits. Self-hosting remains available under the open-source license.

Polar is a strong choice for developers and indie makers who want transparent billing without heavyweight platform complexity. Its API-first design, payment links, subscriptions, and self-host option make it practical for small SaaS products. It may be less ideal for large enterprises needing extensive integrations and advanced billing automation.
