Vibe Kanban is a full-stack, dual-deployment application (local Tauri desktop app + remote cloud service) that combines Kanban-style issue tracking with AI coding agent workspaces. The local backend is a Rust Axum server backed by SQLite, while the remote backend uses PostgreSQL with ElectricSQL for real-time sync. The system allows users to create projects, manage issues, and launch coding workspaces where AI agents (Claude, Codex, Gemini, Copilot, etc.) execute tasks on isolated branches with preview servers, git operations, and automated code review. It includes a relay tunnel system for remote host pairing, a WebRTC transport for low-latency streaming, and an MCP server for external tool integration. The frontend is built with React, Tailwind CSS, and a shared component library, supporting localization in 7 languages. The project is officially sunsetting, as stated in the README, but the codebase remains a substantial example of a modern Rust/TypeScript monorepo with real-time collaboration, AI executor abstraction, and multi-platform delivery.
