ente/ente

Ente is a fully open source end-to-end encrypted cloud platform that provides alternatives to mainstream services like Google Photos and Authy.

The project addresses the need for privacy-preserving cloud storage by implementing end-to-end encryption across all client platforms and the server, ensuring that the service provider cannot access user data. The monorepo contains client applications for iOS, Android, F-Droid, Web, Linux, macOS, and Windows, along with the backend server. The cryptography has been externally audited by multiple security firms. The platform currently powers three applications: Ente Photos for photo backup and management, Ente Locker for storing documents and credentials, and Ente Auth as a two-factor authentication tool.

Ente Photos is the flagship product, offering features including three-way data replication, face detection, semantic search, private sharing, collaborative albums, and family plans. The service operates on a freemium model with ten gigabytes of free storage, though users can also self-host by cloning the repository. Developers should note that the project is a monorepo spanning multiple languages including Dart, Go, and TypeScript, which means adopting it for self-hosting requires managing infrastructure across these different technology stacks.

Almost all open issues are raised by outside users rather than the core team, indicating a substantial base of adopters reporting real-world use. Maintainers typically respond to new issues and pull requests within a few days. Work in the issue tracker is dominated by labels covering authentication, photos functionality, and desktop clients.
