One setup, three surfaces

Everything you need is in the bundle

The installer and portable ZIP both include the visual app, the headless runner, and the agent-facing server. They share one runtime and update together, so a flow behaves the same whichever surface starts it.

UI

Knodr desktop

Build flows on the canvas, edit node settings, inspect live values, use breakpoints, and replay individual nodes.

Knodr.App.exe
CLI

Headless runner

Validate and execute the same .knodrflow files from PowerShell, scripts, or CI without opening the app.

knodr.exe
MCP

Agent tools

Connect an MCP client to the CLI's built-in stdio server so agents can author, validate, run, and debug flows.

knodr mcp

The bundle also carries the Windows automation component used by UI automation nodes. You do not need a separate runtime or SDK.

Read the setup and usage documentation

Install Knodr

  1. 01
    Run the installer

    Open Knodr-win-Setup.exe from your Downloads folder and approve the Windows prompt.

  2. 02
    Launch the app

    Velopack installs Knodr for your Windows user and opens the desktop graph editor.

  3. 03
    Keep it current

    Future releases are detected from the Knodr update feed and applied when you restart.

Build your first flow

Knodr opens on the visual editor. A small flow is enough to learn the core interaction:

1

Add a starting value

Place an Input Value or Manual Input node on the canvas.

2

Connect some work

Add a text, script, HTTP, agent, or AI node and connect compatible ports.

3

Preview the result

Connect a Preview node, run the graph, and inspect each node’s inputs and outputs.

Flows are saved as readable .knodrflow files, so you can keep them alongside a project, review changes, and share them through Git.

Automatic updates

The installed app checks the public Velopack feed at dl.knodr.com. When a newer release is available, Knodr downloads it in the background and offers to restart into the updated version.

Release CI→Cloudflare R2→Knodr

The GUI, bundled CLI, and Windows automation components are delivered together and updated as one release.

Prefer a portable build?

Download the ZIP when you want an unpacked copy that can run from a folder. The installer is recommended for the standard desktop experience and automatic updates.
