Read the Code, Verify the Claims

Budgie uses a source-available license that allows you to view, modify, and contribute to the code while ensuring only we can monetize the official app. This keeps the project sustainable while maintaining transparency.

The repository includes the full React Native app, the AI service layer with on-device LLM and embedding model integrations, the contracts package, and this landing page. Nothing is hidden behind a proprietary SDK or closed binary.

Source-Available License — No Lock-In

Budgie ships under a source-available license that lets you read every line, fork it, and run your own build. Your financial data belongs to you — not to a vendor who can change terms, raise prices, or shut down. If Budgie ever stops meeting your needs, you take your data and your build with you.

Contributing is straightforward: open an issue, discuss the change, and submit a pull request. Features requested by real users and built by real users have a direct path into the app without a gatekeeper commercial roadmap.

Transparency as a Security Property

Public source is not just a development philosophy — it is a security property. Closed finance apps ask you to trust that they do not log your transactions, share data with advertisers, or sell behavioral profiles. Budgie asks you to check. The on-device architecture, AES-256 encryption, and zero-telemetry design are all visible in the repository for any developer to verify.
