Open Source Dart Security Software

Ente is a fully open-source, end‑to‑end encrypted cloud platform designed for securely storing and managing your photos, videos, and 2FA secrets — without needing to trust the service provider. It includes cross‑platform clients and a CLI for self‑hosting needs. Ente is a service that provides a fully open source, end-to-end encrypted platform for you to store your data in the cloud without needing to trust the service provider. On top of this platform, we have built two apps so far: Ente Photos (an alternative to Apple and Google Photos) and Ente Auth (a 2FA alternative to the deprecated Authy). This monorepo contains all our source code - the client apps (iOS / Android / F-Droid / Web / Linux / macOS / Windows) for both the products (and more planned future ones!), and the server that powers them.
