How to Build a Decision Tree for Free
Step 1 — Open the editor
Go to drawdecisiontree.com/build. No account, no setup.
Step 2 — Write your decision logic
Replace the example content with your own questions and outcomes using the DSL format:
name: My Decision Tree
version: 1
Q1: What is your primary need?
A: Troubleshooting [Q2]
B: Product selection [Q3]
Q2: Is the device powered on?
A: Yes [Q4]
B: No [Outcome1]
Outcome1:
name: Power issue detected
description: Check the power cable and try a different outlet.
Step 3 — Run the wizard
Click Run Wizard to test your tree. Answer questions, check the routing, and verify the outcomes.
Step 4 — Share or embed
Copy the share URL to send the tree to anyone. Click Share & Embed to get the iframe code for embedding on any website.
No deployment. No export. Your tree is live immediately.
Why Use a Text-Based Decision Tree Maker?
Most free decision tree tools work like drawing apps — you drag shapes onto a canvas, connect them with arrows, and export an image. This works for creating diagrams, but it has significant downsides:
Slow to build. Positioning shapes and aligning connectors takes time. For a tree with 20 questions, the drawing work dwarfs the logic work.
Hard to update. Changing a question means finding the shape, editing it, and potentially repositioning downstream elements to avoid overlaps.
Static output. The result is an image or SVG — a picture of a decision tree, not a decision tree users can run.
Not version-controllable. Diagram files are binary blobs. You can't diff, review, or roll back changes.
DrawDecisionTree uses plain text. The full decision logic for a 30-question tree fits in a single readable file you can store in Git, review in a pull request, and update with a text editor.
And the output is an interactive wizard — not an image.
