Ente is a multi-product, end-to-end encrypted cloud platform providing photo storage (Ente Photos), two-factor authentication (Ente Auth), secure document vault (Ente Locker), social photo sharing (Ente Space), AI chat assistant (Ente Ensu), ephemeral pastebin (Ente Paste), and media casting (Ente Cast). The system is built as a monorepo with a Go server backend, Rust core libraries for cryptography, machine learning, and media processing, and client applications across web (React/Next.js), mobile (Flutter, native Android/iOS), desktop (Electron), and CLI (Go and Rust). Architecture follows a zero-knowledge design: all encryption (XChaCha20-Poly1305, Argon2, X25519) happens client-side, with keys never exposed to the server. The server handles user accounts, file storage (S3-compatible), billing (Stripe), ML indexing, and sharing. Key entry points include the Go server at `server/cmd/museum`, Rust WASM bindings for web crypto, and Flutter apps with native plugins. Data flows involve client-side encryption before upload, server-side metadata storage in PostgreSQL, and decryption on download. External dependencies include PostgreSQL, S3-compatible object storage, Stripe, ONNX Runtime for ML, and various cloud infrastructure (Cloudflare Workers, Grafana, Prometheus).
