Why Nodlyn?

Built for everyone —
from beginners to pros

You don't need to be a developer to automate. But if you are one, Nodlyn has the advanced tools you expect.

🎯

Easy for beginners

No programming knowledge required. Just drag blocks, connect them, and press save. It's as simple as drawing a flowchart on a whiteboard.

⚡

Powerful for professionals

Multi-branch logic, conditional switches, parallel execution, scheduled triggers, webhook endpoints, and a full REST API for developers who need control.

🏠

Runs locally, your data stays private

No cloud subscription. No data leaves your machine unless you choose to send it. Install once, run forever — on your own hardware.

Features

Everything included.
Nothing locked.

Every feature is available in the free beta. No tiers, no paywalls.

🔀

Visual Drag & Drop Builder

Infinite zoomable canvas. Drag nodes from the library, connect them with edges. Conditions, switches, loops — all visual.

↩️

Undo & Redo

Made a mistake? Just Ctrl+Z. Full undo/redo history so you can experiment freely without fear of breaking anything.

👥

User Management

Create user accounts with role-based permissions. Admins, operators, viewers — control who can build, run, or just monitor workflows.

📦

Export Runtime Agents

Export your workflows as standalone runtime packages. Deploy them to remote machines, edge devices, or servers — they run independently.

🧩

Custom Components

Build your own nodes as plugins. Package custom business logic, proprietary protocols, or internal APIs into reusable workflow blocks.

🧠

AI & MCP Agent Nodes

Drop AI blocks into any workflow. Classify, summarize, call LLMs — or let an autonomous AI Agent discover and use tools from any MCP server.

📡

IoT & Device Control

Connect ZigBee, Z-Wave, MQTT, Bluetooth devices. Auto-discovery finds devices on your network. Pair in seconds, automate in minutes.

🔌

200+ Connectors

HTTP APIs, SFTP, Grafana, email, databases, Azure IoT, Tuya, OCR, barcode scanners, file system, serial ports, printers, webhooks — and custom plugins for anything else.

🛡️

Security & Audit

AES-256 encrypted credential vault. Full audit logging. API key authentication. Optional secure tunnel with path-level restrictions.

📊

Real-Time Monitoring

Watch workflows execute live on the canvas — nodes light up as they run. Device health dashboards. Instant failure alerts via email or webhook.

⏰

Schedules & Triggers

Run workflows on a cron schedule, on device events, on webhook calls, or manually. Combine multiple triggers in one workflow.

📝

Sticky Notes & Docs

Add color-coded sticky notes directly on the canvas to document your logic. Leave instructions for teammates or your future self.

⬛

Command Line Execution

Run shell commands, scripts, and system utilities directly from your workflow. Capture stdout, stderr, and exit codes — with operator approval for safety.

☰

Ladder Diagram View

Switch between the drag-and-drop canvas and a PLC-style ladder diagram. Contacts, coils, timers — familiar to industrial engineers. Saved per workflow.

A closer look

See what makes Nodlyn
different

A canvas that feels like a whiteboard

The workflow builder is designed so anyone can use it — not just engineers. Pick a block from the sidebar, drop it on the canvas, and connect it to another block. That's it. You just built an automation.

  • Drag blocks from a categorized library
  • Connect them visually — like drawing a flowchart
  • Undo / redo any change with Ctrl+Z / Ctrl+Y
  • Zoom, pan, minimap for large workflows
  • See your workflow run in real-time with animated nodes
  • Switch to Ladder Diagram view for a PLC-style representation

📧 Action B

Multi-user with role-based access

Nodlyn isn't just a single-user tool. Add team members with different permission levels. Control who can create workflows, who can only run them, and who can just view the dashboards.

  • Admin — full control: users, settings, workflows
  • Operator — create and run workflows, manage devices
  • Viewer — read-only: monitor executions and device health
  • API keys for service-to-service authentication
  • Full audit log: who changed what, when

Export & deploy anywhere

Build your workflow on your desktop, then export the runtime package and deploy it to a remote server, a Raspberry Pi, or an edge gateway. The runtime agent runs independently — no GUI needed.

  • One-click export to a standalone runtime
  • Deploy to Windows, Linux, or macOS
  • Edge devices: Raspberry Pi, industrial gateways
  • Runtime auto-connects back to the main dashboard
  • Monitor remote agents from a single interface

AI Agents that use real tools

Connect any MCP (Model Context Protocol) server and let an AI agent autonomously discover tools, reason about what to do, execute actions, and iterate until it solves your task — all inside a visual workflow node.

  • MCP Tools — discover what any MCP server can do
  • MCP Tool — call a specific tool with dynamic arguments
  • MCP Resource — read data exposed by MCP servers
  • LLM Call — prompt any OpenAI-compatible model (GPT, Claude, Ollama, LM Studio)
  • AI Agent — autonomous loop: discovers tools → reasons → calls → repeats

✅ Answer

Extend with custom components

Need a node that doesn't exist? Build your own. The plugin system lets you create custom workflow blocks that package your proprietary logic, internal APIs, or specialized hardware drivers.

  • Write plugins in C# with a simple interface
  • Your plugin appears in the node library automatically
  • Package and share with your team
  • Access any .NET library or NuGet package
  • Hot-reload: drop DLLs into the plugins folder
MyCustomNode.cs
public class MyCustomNode : IWorkflowStep
{
    public async Task<StepOutcome> ExecuteAsync(...)
    {
        // Your logic here
        var result = await CallMyApi();
        return StepOutcome.Ok(result);
    }
}

Run any command from a workflow

The Command Line node lets you execute shell commands, scripts, and system utilities directly from your workflow canvas. Capture output, check exit codes, and branch your logic accordingly.

  • Run any OS command: ping, curl, python, dotnet, etc.
  • Capture stdout, stderr, and exit code as workflow data
  • Template arguments with {{field}} and {{$var.key}}
  • Configurable timeout and working directory
  • Dangerous security level — requires operator approval

Two ways to see your workflow

Switch between the standard drag-and-drop canvas and a PLC-style ladder diagram — right from the editor toolbar. Each workflow remembers its preferred view mode, and you can change it anytime.

  • Canvas view — infinite zoomable flow editor with drag & drop
  • Ladder view — contacts (NO/NC), coils, timers — familiar to PLC engineers
  • Power rails, rungs, and parallel branches rendered as SVG
  • View mode saved per workflow — persists across save and reload
  • Choose the view mode in the Workflow Wizard or AI Assistant
