**ffinn** is a free, MIT-licensed, **multi-tenant SaaS starter kit** with built-in **AI agents**. You get a production-minded foundation (auth, roles, billing, admin) plus:

a build agent that turns plain-English feature requests into code, pull requests, staging deployments and production releases, and
chat assistants you create yourself, each with its own instructions, file uploads and conversation history, like the ChatGPT and Claude web apps but on your own stack.

Bring your own keys for OpenAI, Anthropic Claude, Google Gemini, Azure OpenAI, GitHub Models, Ollama or any OpenAI-compatible server. No licence fees and no vendor lock-in.

Built with a **Python/FastAPI** backend and a **Next.js** frontend. Website and docs: **[ffinn.ca](https://ffinn.ca)**.
