Polar

About

Billing and global tax handled, built for devs

Polar acts as merchant of record, so international tax compliance, fraud and disputes are its problem rather than yours. It covers checkout links or APIs, subscriptions, usage-based billing and automatic delivery of benefits like license keys, downloads and GitHub repo access. The platform is Apache 2.0 on GitHub and ships an official remote MCP server, with a separate sandbox endpoint for testing.
