LOOPZE

Industrial Flow Automation

LOOPZE is a lightweight, high-performance flow automation platform built for industrial environments. Think Node-RED, but written in Go — compiled to a single binary with zero dependencies.

Designed for automation technicians, PLC programmers and engineers who think in signal flows and function blocks. LOOPZE brings visual flow-based programming to the edge — with first-class support for industrial protocols like MQTT, Modbus and OPC UA.

Where to start

  • Getting Started

    Install LOOPZE, build your first flow and learn the core concepts.

    Installation

  • Nodes

    Reference documentation for every built-in node — Inject, Function, MQTT, Modbus, OPC UA and more.

    Node reference

  • Scripting

    JavaScript via Goja for complex logic, expr-lang for fast expressions.

    Scripting guide

  • Deployment

    Run LOOPZE on Linux, Windows, macOS, ARM. Systemd, Docker, edge boxes.

    Deployment

Highlights

  • Single binary — no runtime dependencies, no package managers.
  • Visual flow editor — drag-and-drop, built with Vue 3 and Vue Flow.
  • Industrial first — MQTT, Modbus TCP/RTU, OPC UA (read / subscribe / write with structure-aware ExtensionObject support and address-space browser), serial.
  • Embedded NATS — built-in message broker for context, debug streams and fleet communication.
  • Encrypted credentials — secrets stored separately, AES-256-GCM.
  • Local user accounts — Argon2id password hashing, three roles (admin / editor / viewer).

LOOPZE — Small, hard, reliable. Like the stone that sparks the fire.
