About Diagram Studio

The Diagram Editor is a general-purpose, browser-based visual diagramming tool that lets you compose flowcharts, system architecture diagrams, network topology maps, and wireframes using a rich drag-and-drop canvas. Pick shapes from categorized palettes — basic geometry, flowchart symbols, UML shapes, network icons, and UI wireframe components — drop them onto the canvas, connect them with smart routing connectors, and annotate everything with styled text labels. No account required and no software to install; export your work as SVG, PNG, or a JSON file that can be reloaded later.

Features

  • ✓Categorized shape library: flowchart, UML, network, containers, and wireframe palettes
  • ✓Smart connectors with four routing styles: elbow, rounded, curved, and straight
  • ✓Multi-select, group, align tools for precise layout (left, right, center, top, middle, bottom)
  • ✓Resizable shapes with snap-to-grid and snap-to-shape alignment guides
  • ✓Rich text labels with font family, size, color, bold, and italic formatting
  • ✓Layer panel for organizing diagram elements with show/hide controls
  • ✓Save and reload diagrams via JSON file export/import (no browser auto-save — press Save explicitly)
  • ✓Export as SVG (vector), PNG (2× raster), or JSON (full diagram state for reloading)

Common Use Cases

  • Sketching system architecture diagrams for design proposals and RFCs
  • Creating network topology maps for infrastructure documentation
  • Building low-fidelity UI wireframes for product mockups and user testing
  • Diagramming deployment pipelines and cloud infrastructure layouts
  • Producing presentation-ready flowcharts without dedicated desktop diagramming software

Frequently Asked Questions

QIs my diagram data stored on a server?

No. Nothing is sent to a server at any point. Your diagram exists only in memory while the page is open. To preserve your work, use the Save (JSON) button to download a file — the editor does not automatically write to browser local storage.

QCan I import a diagram I created elsewhere?

Yes, if it was previously saved using this editor's Save (JSON) button. The Open button accepts `.json` files in the tool's own format. External diagram formats (e.g. Visio, XML-based tools) are not currently importable.

QWhat connector routing styles are available?

Four routing styles are available: Elbow (orthogonal — right-angle bends), Rounded (smooth right-angle bends), Curved (Bézier arc), and Straight (direct line). Select a connector to change its routing in the Style panel on the right.

QCan I collaborate on a diagram in real time with teammates?

Real-time collaboration is not currently supported. For team collaboration, export the diagram as JSON and share the file, or use the SVG export for a read-only shareable image.
