Entropic is a local-first desktop AI workspace built with Tauri and React. It provides a full desktop environment including chat with an AI agent, file management (Finder), web browsing, office document editing (OnlyOffice integration), voice control, task board with cron jobs, and an integration marketplace (OAuth for Google, Outlook, Slack, etc.). The application runs a sandboxed runtime (OpenClaw) inside Docker/Colima on macOS/Linux or WSL2 on Windows, ensuring secure execution of agent actions. Communication with the agent gateway happens via WebSocket with structured RPC frames. The system supports two modes: local API keys (user provides LLM keys) and managed proxy mode with hosted authentication and billing via Supabase/Stripe. The architecture is a monolith with separate microservices for browser automation (Playwright) and skill scanning (Cisco AI Defense). The frontend uses React 18, TypeScript, Vite 5, and Tailwind CSS 4, while the backend is Rust with Tauri v2 plugins for deep-link, updater, store, stronghold, and shell access. The codebase demonstrates strong engineering practices with reusable hooks for audio recording/transcription, a custom markdown renderer with workspace link support, and a resilient WebSocket client. However, some components are monolithic (Chat.tsx ~4000 lines, Files.tsx ~3000 lines) and there are hardcoded model lists and pricing that may drift over time.
