Architecture Overview

How LumenFlow is structured for reliability, extensibility, and auditability.

How LumenFlow is built#

LumenFlow uses a layered architecture that keeps each part of the system independent and replaceable. This design ensures reliability, flexibility, and a complete audit trail.

The three layers#

Your interface#

The web dashboard is where you interact with LumenFlow — manage workspaces, chat with Sidekick, review proposals, and monitor activity. It's designed for speed and clarity.

The intelligence layer#

This is where LumenFlow's core capabilities live:

  • Sidekick — your AI assistant that proposes actions and executes approved tasks
  • Governance engine — evaluates your rules and routes actions for approval
  • Audit trail — records every action with full context for compliance

Secure infrastructure#

The infrastructure layer connects to the services you choose:

  • Inference — start with LumenFlow managed inference or connect your own model key
  • Your connected services — Gmail, Google Calendar, Outlook, Greenhouse, Slack, and custom MCP tools
  • Connected runtimes — enroll governed external runtimes through the control-plane SDK
  • Encrypted storage — all data encrypted at rest and in transit

Why this matters#

This separation means LumenFlow is extensible (swap providers without affecting your workflows), auditable (every action is logged at every layer), and reliable (each layer can be updated independently).
