How much you save switching from Polar to Tiun
Annual fees on international subscription revenue with currency conversion. The percentage looks small. The number doesn't
The fee gap compounds
A 2-point fee gap sounds small until you do the math. On $500k of international subscription revenue, Tiun keeps over $10,000 a year in your account, and that's before counting the engineering hours you'd otherwise spend on auth, webhooks, and entitlement code
Tiun replaces Polar, Auth0, and your customer DB
Polar replaces Stripe + Stripe Tax. Tiun replaces Stripe + Stripe Tax + Auth0 + your customer database + your analytics tool
Skip the Auth0 bill and the webhook handlers
Polar handles billing. You still need auth (Clerk, Auth0, build-your-own) and the webhook handlers that keep auth state in sync with billing state. Tiun ships authentication, social login, multifactor, and entitlements as part of the platform, queryable through the same SDK
Email + password login — included
Social SSO (Google, GitHub) — included
Multifactor auth (SMS + Email) — included
User profile + entitlements — live state
Customer, subscription, and payment state in one query
No more reconciling webhook payloads from Stripe, Auth0, and a tax service to figure out what your customer can access right now
MCP server + GitHub Skill for AI coding agents
Install once. Your agent reads Tiun's API as native context, wires up auth and billing in your codebase, and the integration is live in minutes
