Secure, end-to-end encrypted messaging platform for developers. Native performance meets maximum privacy.
QuillCrypt provides a developer-centric communication tool where security is not an afterthought. By combining modern cryptographic standards with a high-performance stack, we ensure that your conversations remain yours.
Our system is split into three primary components:
- app: Cross-platform desktop/mobile client built with Tauri, React, and TypeScript. Handles all encryption/decryption locally.
- backend: High-performance Go service using Hexagonal Architecture. Manages secure message routing and real-time delivery via WebSockets.
- proto: Shared Protocol Buffers definitions for consistent, type-safe communication between client and server.
- Languages: Go, Rust, TypeScript.
- Frontend: React 19, Tailwind CSS, Material 3.
- Backend: PostgreSQL, Redis, Uber-Go Zap.
- Infrastructure: Docker & Docker Compose.
- Local-First Encryption: Keys never leave your device.
- Modern Standards: Leveraging Tauri's Stronghold and audited crypto libraries.
- Transparency: Fully open-source under the AGPL-3.0 license.
Under Active Development. Features are being implemented rapidly. Not recommended for production use until versioned releases begin.
"Lock your thoughts, keep the quill."
