Ecosystem Analysis

Complete analysis of the Synap ecosystem architecture

Executive Summary​

This document provides a complete analysis of the Synap ecosystem, including:

  • 16 packages organized in a monorepo structure
  • 2 applications (Data Pod API, Admin UI)
  • Hub & Spoke architecture with clear separation of concerns

  • api_keys (Hub authentication)
  • knowledge_facts (knowledge graph)
  • conversation_messages (chat history)

@synap/storage (v1.0.0)​

Role: Object storage abstraction
Capabilities:

  • Cloudflare R2 integration
  • S3-compatible API
  • Presigned URLs for secure access

Domain Layer​

@synap/domain (v1.0.0)​

Role: Business logic and domain services
Capabilities:

  • Entity services (Notes, Tasks, Projects)
  • Knowledge service (semantic search, facts)
  • Conversation service
  • Vector search service

AI & Intelligence Layer​

@synap/ai (v1.0.0)​

Role: Local AI agent orchestrator (Data Pod)
Capabilities:

  • LangGraph agent graph
  • Intent classification
  • Action planning
  • Tool execution
  • Semantic search
  • Knowledge graph integration

Key Components:

  • agent/graph.ts - Main LangGraph workflow
  • agent/intent-classifier.ts - Intent analysis
  • agent/planner.ts - Action planning
  • agent/executor.ts - Tool execution
  • tools/ - Dynamic tool registry

Note: Intelligence capabilities can be added via plugins (single agents, agent graphs) or external services (marketplace). See Plugin System for details.

Hub Protocol Layer​

@synap/hub-protocol (v1.0.0)​

Role: Protocol schemas and validation
Capabilities:

  • HubInsight schema (Zod)
  • Action schema
  • Analysis schema
  • Validation functions
  • Type guards

@synap/hub-protocol-client (v1.0.0)​

Role: Type-safe client for Hub Protocol
Capabilities:

  • tRPC client for Data Pod communication
  • Token management
  • Data request handling
  • Insight submission

API Layer​

@synap/api (v1.0.0)​

Role: tRPC API server (Data Pod)
Capabilities:

  • Dynamic router registry (plugin system)
  • 8 core routers:
    • events - Event logging
    • capture - Thought capture
    • notes - Notes management
    • chat - Conversational interface
    • suggestions - AI suggestions
    • system - System metadata
    • hub - Hub Protocol V1.0
    • apiKeys - API key management
  • Event publishing (Inngest)
  • Event streaming (WebSocket)
  • Authentication middleware

Authentication Layer​

@synap/auth (v2.0.0)​

Role: Authentication and authorization
Capabilities:

  • Ory Kratos integration (identity)
  • Ory Hydra integration (OAuth2)
  • Token exchange (RFC 8693)

Application Layer​

Data Pod API (apps/api)​

Role: Main API server for Data Pod
Technology: Hono + tRPC
Capabilities:

  • Serves @synap/api router
  • Authentication middleware
  • Security headers
  • Rate limiting
  • CORS configuration

Note: External intelligence services are third-party services that can be connected via the marketplace using the Hub Protocol. They are not part of the core open-source Data Pod.
