Tanso provides a self‑hosted platform that combines usage‑based and subscription billing with real‑time entitlement enforcement, returning an allow or deny decision directly in the request path. It lets developers define plans, credit pools with hard limits, and optional Stripe integration, while a built‑in MCP server enables AI agents to interact with billing logic. The solution runs via a single Docker Compose command and is released under AGPL‑3.0.

Problem
Developers and SaaS providers often rely on external billing services that generate invoices after the fact, lacking immediate enforcement of usage limits and requiring external accounts or complex integrations. This can lead to over‑consumption, delayed revenue recognition, and difficulty integrating billing decisions directly into application request flows.
Solution
Tanso offers a self‑hostable platform that combines usage‑based and subscription billing with real‑time entitlement checks embedded in the request path, returning an explicit allow or deny decision. Users define plans, credit pools with hard limits, and entitlements, then meter usage via API calls. The system bills usage and subscriptions automatically and can forward payments to Stripe if desired. A built‑in MCP server enables AI agents to programmatically adjust billing logic. The entire stack runs from a single Docker Compose command, eliminating the need for external accounts and allowing full control over data and licensing under AGPL‑3.0.
Target Audience
Primary customers are SaaS developers, API providers, and platform teams that need immediate usage control and integrated billing without relying on third‑party services.
