All-in-One SaaS Foundation
A self-hosted platform for authentication, subscriptions and credit billing of your SaaS apps — all with a single docker compose up. Your apps talk to two APIs and never touch Keycloak, Stripe or Paddle directly.
The enterprise edition of Sitebin.io builds on the SaaS Stack for accounts, tiers and billing.
Features
Multi-tenant auth & SSO
One auth realm for all apps: sign in once, signed in everywhere — with per-app branded login pages and social login (Google, Microsoft, GitHub, Apple).
Subscriptions, credits & one-time payments
Any tier structure, consumable credits with atomic deductions and one-time purchases — Stripe or Paddle, swappable without touching app code.
Account console & plan page
Hosted pages for password, sessions, second factor, data export and self-service deletion, plus plan changes — your app builds none of it.
Terms & consent
Platform terms, your own terms, data processing agreement and marketing consent in one flow at sign-in — versioned, recorded and exportable.
Widgets & SDKs
Embeddable web components for pricing, credits and account, plus SDKs for .NET, Go and Python.
MCP authorization & admin portal
OAuth authorization for MCP servers, license issuance, transactional mail and a central admin portal with a user directory.
Tech Stack
Planned as Open Source
The SaaS Stack will be released as an open-source project under the MIT license. Stay tuned or contact us for early access.
