Built with cutting-edge web technologies and packaged as a native macOS application, ChartLy combines the flexibility of web-based tools with the performance and integration of a desktop app.
Professional Flowchart Creation
Create sophisticated flowcharts with an intuitive visual interface. Whether you're mapping out software architecture, business processes, or technical workflows, ChartLy provides the tools you need to bring your ideas to life.
Template Library
Jump-start your diagrams with ready-made templates, including API Request Flow, CI/CD Pipeline, Authentication Flow, and Microservice Architecture. Start from a proven structure instead of a blank canvas.
Undo & Redo
Experiment freely with full undo and redo history. Step back through your changes at any time, so you can try ideas without losing work.
Enhanced Editing Tools
Fine-tune every element with dedicated dialogs for editing nodes, edges, and groups, plus diagram-level settings. Shape previews show exactly what each node will look like before you add it.
Mermaid.js Integration
ChartLy fully integrates with Mermaid.js, the industry-standard diagramming library. Write Mermaid syntax in the built-in code editor and see your diagrams render instantly in the preview pane. Perfect for developers who prefer code-based diagramming or need to version-control diagrams alongside their code.
Multiple Tabs & Workspace Management
Work on multiple flowcharts simultaneously with a tabbed interface. Each tab maintains its own state, letting you switch between projects seamlessly.
Real-Time Preview & Live Editing
Experience true WYSIWYG editing with instant preview updates. As you modify your Mermaid code or make visual changes, see the results immediately.
Comprehensive Toolbar & Elements
Access a full suite of flowchart elements including start/end nodes, process nodes, database nodes, junction points, text elements, comments, and various connection types (arrows, bidirectional, lines, cross edges).
Professional Dark Theme
A carefully crafted dark theme optimized for extended editing sessions. The high-contrast design reduces eye strain and matches modern development environments.
Pan & Zoom Navigation
Navigate large, complex diagrams with intuitive pan and zoom controls. Zoom in to focus on specific sections or zoom out to get the full picture.
Smart Data Management
Your work is automatically saved to local storage, so you never lose progress. The app remembers your layout preferences and tab configurations across sessions.
Export & Sharing
Export your completed flowcharts as high-quality PNG images for presentations, documentation, or sharing with your team.
