NeoAgent

Architecture

NeoAgent is a Node.js service with Flutter clients. The server owns authentication, model access, agent execution, tools, integrations, automation, memory, persistence, and real-time state.

Main components

Flutter clients and messaging channels
                |
        Express + Socket.IO
                |
  agents / AI engine / tasks / integrations
                |
 runtime backends / SQLite / agent data

Server

server/index.js creates the application and service managers. Express routes handle HTTP boundaries and delegate behavior to services. Socket.IO publishes run progress, approvals, messages, device state, and operational updates.

The server uses CommonJS. Routes should remain thin; business logic belongs in server/services/.

Clients

The Flutter codebase produces the web operator interface, Android client, desktop clients, and Android launcher build. MainController is the root application state object. Platform behavior is implemented through conditional bridge files and native Android code where required.

Persistence

NeoAgent uses one better-sqlite3 database instance. It stores users, agents, settings, conversations, runs, tasks, integration connections, memory, health data, permissions, and operational state.

Runtime files live outside the package source under NEOAGENT_HOME. Schema changes are applied through the migration layer rather than ad hoc service SQL.

Execution runtimes

Browser and terminal tools normally use the per-user isolated runtime. A user can select a paired Chrome extension for browser work or a paired desktop client for shell and desktop control. Android remains a host ADB capability.
