[FR] CLI Interface for Local AI Agent Integration & Headless Operations

[The-magic]

Description

AppFlowy currently requires a GUI interface for all interactions. This feature request proposes a Command-Line Interface (CLI) that allows programmatic, headless interactions with local AppFlowy instances, enabling:

1. Local AI Agent Integration - AI agents can programmatically create, read, update, and delete workspaces, documents, and databases without a GUI
2. Automation & Scripting - Users can automate complex workflows through CLI commands
3. Data Control & Privacy - Users maintain full control over their data while leveraging agentic capabilities
4. Server-like Deployment - AppFlowy can act as a backend service for applications that need collaborative workspace management

Example Use Cases:

# Create a new document
appflowy-cli doc create --workspace-id <id> --title "Meeting Notes"

# Add content to a document
appflowy-cli doc add-content --doc-id <id> --content "AI Agent Summary: ..."

# Create a database/table
appflowy-cli database create --workspace-id <id> --name "Tasks"

# Query data
appflowy-cli database query --db-id <id> --filter "status=pending"

# List all workspaces
appflowy-cli workspace list

# Initialize local AppFlowy instance
appflowy-cli init --data-path ~/.appflowy-data

Impact

Who Benefits:

• AI/Agent Developers - Can integrate AppFlowy as a persistent knowledge store for autonomous agents without UI overhead
• DevOps/Infrastructure Teams - Can deploy AppFlowy as a service component in larger systems
• Privacy-Conscious Users - Can build custom applications on top of AppFlowy while retaining data sovereignty
• Automation Engineers - Can create sophisticated workflows combining AppFlowy with other tools
• Enterprise Users - Can integrate AppFlowy into internal tools and workflows without GUI constraints
• Open-Source Community - Expands AppFlowy's use cases and adoption in agentic/automation ecosystems

Market Impact:

• Positions AppFlowy as the leading open-source alternative for AI-driven knowledge management
• Attracts developers building AI agents, automation tools, and backend systems
• Opens new market segments (SaaS integrations, API-based services, agent frameworks)
• Differentiates from closed-source competitors (Notion, others) by enabling deep programmatic control

Additional Context

Technical Approach (suggestion):

The CLI would leverage AppFlowy's existing Rust backend (flowy-core) which is already decoupled from the Flutter UI:

1. Create a new Rust binary (appflowy-cli) that initializes AppFlowyCore without Flutter
2. Expose core operations through command handlers that map CLI commands to existing event dispatch system
3. Support both local and cloud workspaces
4. Output structured data (JSON/YAML) for script integration
   5.Provide event streaming for real-time updates

Sample Integration Flow:

Local AI Agent
     ↓
CLI Client (JSON/Protobuf)
     ↓
AppFlowy CLI Binary
     ↓
AppFlowyCore (Rust)
     ↓
SQLite/CollabDB (Local Storage)

Key Features to Include:

✅ Basic CRUD operations (documents, databases, workspaces)
✅ Authentication (local & cloud modes)
✅ Query & filtering capabilities
✅ Batch operations for efficiency
✅ Event subscriptions/webhooks
✅ JSON/Protobuf output formats
✅ Configuration management (data paths, logging)
✅ Error handling & logging

Related Use Cases:

AI agents storing research & analysis results
Automation platforms (n8n, Zapier) integration points
Knowledge graphs for ML training
Collaborative AI assistant backends
Internal tool integrations (Wiki + Agent interface)

Why This Matters:

AppFlowy's vision is "data privacy first" and "community-driven extensibility." A CLI is a natural extension that empowers users and developers while maintaining full data sovereignty. In the era of AI agents, having programmatic access to local, privacy-preserving storage is increasingly critical.
