Create quick diagrams with draggable nodes. Expandable canvas prevents long diagrams from getting cut off.
Tip: Select two nodes then click Connect Selected. Drag nodes to reposition. Canvas auto-expands as your diagram grows.
Diagram Maker is a free, browser-based visual tool for building node-link diagrams with draggable blocks and connectors. Create workflows, mind maps, or relationship sketches without installing software or creating an account.
Diagram Maker is a lightweight diagramming tool that lets you create node-link visuals directly in the browser. Add labeled nodes to an auto-expanding canvas, then connect any two nodes with directional arrows to represent relationships, sequences, or dependencies. Every node is fully editable and draggable, so you can rearrange the layout as your ideas evolve. The finished diagram exports as a clean SVG file or can be sent straight to print, making it useful for quick brainstorming, documentation, and stakeholder presentations alike.
Click Add Node to place a new editable block on the canvas. Double-click a node to rename it, or drag it to reposition. Select two nodes by clicking each one, then click Connect Selected to draw a directional arrow between them. The canvas auto-expands as you add nodes toward the edges, so long or wide diagrams are never cut off. Give your diagram a title using the text field at the top. When finished, click Download SVG to save a scalable vector file, or use Print to output directly from the browser.
