dNodes.io delivers strategic clarity.

The world’s most powerful web-based decision tree platform.

The Ultimate Tool for Interactive Strategic Planning

dNodes.io is the ultimate tool for strategic planning with its flexible, easy-to-use web interface. The interactive design makes it simple to revise assumptions, helping teams to consider different perspectives on the fly and develop robust strategies. dNodes.io provides a platform where early decisions and risks can be easily assessed  and communicated — laying the foundation for a project's success and driving value.

Decision Trees

Drag and drop decision nodes, chance nodes and end nodes to build the main problem structure. Copy, paste or move branches and add annotations.

Intuitive interface

Facilitate for interactive strategic planning using our web-based and intuitive interface. Engage in thoughtful, collaborative discussions to uncover key insights.  


Use variables to assign payoffs to branches in the tree. Determine how uncertain variables will impact the expected pay-off, accumulated uncertainty and optimum path.


Calculate the tree, highlight the optimum path, add milestones and compare alternative strategies and possible outcomes for additional insight.


Bar charts, distribution charts, tornado diagrams and waterfall diagrams. For any node or branch in the tree.


Export your decision tree in PNG, SVG or Pdf-format. Vector-based export enables high-resolution images in presentations or prints.


Save and download your analysis in a compact .JSON format. Send it off to colleagues for input or load it on any computer for team reviews.


Get access to important software updates as part of your subscription plan. No installs required, completely hazzle free.

No installation. No plugins. No outdated user interface. No complex simulations. Yet, truly powerful!

How Do You Explain...

When others are able to decide and achieve results that you never even thought about? Or better yet, how do you explain when things don't go as planned with a business decision that you have made?

Decision analysis software is designed to help provide you with the insights necessary to make the best, most informed strategic decisions for your business.

With dNodes.io, we offer a beautifully intuitive and web-based application.

Decision Tree Software Demo

Decision Tree Module

dNodes.io is the first ever web-based decision tree tool that can instantly calculate and visualise decision trees with statistical distributions and milestones.

How to Build a Decision Tree
Variables Module

This is solved without the use of Monte Carlo simulation which significantly reduces the user threshold and makes it possible to run dNodes.io in a web browser. Milestones can be connected to decisions and outcomes and visually reflect time consequences.

Good Decisions Matters

Use dNodes.io to evaluate the trade-off between alternatives, and making sure that risks and uncertainties are identified and addressed. Good decision-making skills within a company is critical, they increase the likelihood that the right choices are being made. Use dNodes.io to align team members and set focus on the right issues. Because good decisions matters.

dNodes.io The basics
The basics

In this video we demonstrate the basics of dNodes.io. You will see how easy it is to build and modify a decision tree, as well as some of the most useful layout options and settings.

dNodes.io Working with variables
Working with variables

Working with variables is an alternative to assign payoffs directly in a tree. In this video we demonstrate how you can use variables as an effective and systematic way to update payoffs in the tree, or for more advanced calculations using our extensive math library.

Probabilities and charts

Making the correct decisions are vital for your business. We demonstrate how the decision tree provides you with the optimal path, and how you can use visual charts such as distribution charts, tornado diagrams and waterfall diagrams, to provide additional insight.

Here’s Why We Created It

“dNodes.io is designed to reduce the complexity of decision analysis software. Above all, it enables more active use of decision analysis methodology and encourages team collaboration. Furthermore, dNodes.io allows you to sketch out strategies live in a meeting, to test assumptions and structure discussions. At last, project teams and management can experience the power of decision modelling hands-on, through an intuitive, yet powerful application!”
