nimbus

Nimbus gives Google's Gemini LLM access to your desktop so it can easily read files and run code for you.

architecture

• Flutter desktop app that targets MacOS and Linux with a single codebase.
• Firebase Firestore is used to preserve chats and messages with security rules to ensure that only authenticated users can read or write their data.
• Firebase Authentication is used to let users log in using email or Google.
• There is no backend. The Flutter client uses a pass-through server proxy to directly call the Google AI Gemini API.
• Firebase Hosting for the landing page

next

• Firebase App Check to increase security
• Use Firebase Storage when files exceed the size limit for direct upload to Google AI Gemini API
