In their own words
Fungies
Fungies is a Merchant of Record platform for selling SaaS, games, subscriptions, digital products, downloads, and game assets. Its no-code store builder includes more than twenty templates, custom domains, hosting, and a CDN. Sellers can choose hosted, overlay, or embedded checkout, localized for customers’ language, currency, and payment methods. Subscription tools cover recurring and usage-based billing, trials, customer portals, invoicing, and retry handling. Fungies says it manages tax registration, calculation, collection, remittance, and filing across the 27 EU states, the UK, US sales tax, and GST. It lists support for 250+ payment methods in 150+ countries, along with developer tools such as a REST API, webhooks, SDKs, CLI, and MCP server. The Free forever plan costs nothing, with a 5% + 50¢ fee per sale and no monthly fee. There is no separate payment test mode, so checkout purchases are real transactions.
Polar
Polar is a billing stack for AI products, combining subscriptions, usage billing, credits, invoicing, and merchant-of-record services. It collects usage events into customer meters and adds metered charges to the next invoice. Meters can count, sum, average, find minimums or maximums, and track unique values. Usage collection options cover LLM activity, streaming responses, S3-compatible storage, elapsed time, and manually submitted events; LLM integrations include the Vercel AI SDK and compatible models that return usage data. As merchant of record, Polar says it resells products in over 100 markets and handles payments, sales tax, fraud, refunds, and chargebacks. Its hosted checkout supports localized currencies and includes sales tax. Automated benefits include usage credits, license keys, file downloads up to 10GB, and invitations to private GitHub repositories and Discord. Polar lists apps for iOS and Android and plugins for Raycast and Framer. The Starter plan is free; Pro is $20/month, Growth is $100/month, and Scale is $400/month, with transaction fees on each plan. Usage meters do not block activity when a quota is exceeded; the product using Polar must enforce limits.
