AppFlowy is a free and open-source AI collaborative workspace designed as a privacy-first alternative to proprietary productivity tools like Notion. It brings together projects, wikis, tasks, and team collaboration into a unified, customizable environment, giving users complete control over their data.

💡 Core Philosophy & Data Ownership

AppFlowy’s mission is defined by three fundamental values:

Data Privacy First: AppFlowy is a local-first application. All your personal data is stored on your device by default, and it features 100% offline mode. Users can choose to use the official cloud service or, critically, self-host their workspace (via Docker) for complete data sovereignty and ownership.
Reliable Native Experience: Unlike many web-wrapper-based applications, AppFlowy is engineered to deliver a fast, responsive, and truly native user experience across all supported platforms.
Community-Driven Extensibility: Licensed under the AGPL-3.0, the project fosters a vibrant community that contributes to new features, plugins, and templates, ensuring the platform remains highly adaptable.

✨ Key Features

AppFlowy provides a flexible, block-based editor and powerful tools to manage tasks and knowledge:

Block-Based Editor: Use a flexible editor to create documents using rich text, code blocks, lists, and checklists. It fully supports Markdown syntax for fast editing.
Databases & Views: Organize structured information with powerful databases. Data can be visualized in customizable views, including Grid (Table), Board (Kanban), and Calendar.
AI Workspace: Integrated AI features (“AI Teammate”) assist with summarizing, writing, and brainstorming. It is designed for privacy, offering the ability to run local AI models (like Llama 3 or Mistral 7B) directly on your machine using tools like Ollama.
Customization: Personalize the workspace with custom views, content types, and data labels. Users can customize themes, fonts, and page styles.
Cross-Platform Support: Native applications are available for Windows, macOS, Linux, iOS, and Android.

🛠️ Technology Stack (Flutter & Rust)

AppFlowy’s architecture utilizes a modern, performance-oriented stack chosen for speed and cross-platform consistency:

Frontend (UI): Flutter is used to build the user interface from a single codebase, which allows for consistent, high-performance native experiences across all operating systems.
Backend (Core Logic): Rust powers the core business logic, data processing, and infrastructure layer. Rust is known for its excellent performance, memory safety, and reliability, contributing to the application’s stability.
