ClickCharts is a Mac application from NCH Software that lets you build flowcharts, process maps, data-flow diagrams, UML charts, and org trees using a drag-and-drop canvas.
What is ClickCharts?
ClickCharts is a dedicated visual diagramming tool for macOS, designed to turn abstract workflows and system architectures into clean, shareable charts without requiring a design background. Whether you are mapping a customer-service escalation path or sketching a software data flow before writing a single line of code, ClickCharts gives you a structured canvas and a library of shapes to work with rather than forcing you to wrestle with a generic drawing app.
NCH Software has been shipping productivity utilities for decades, and ClickCharts fits that same philosophy: opinionated defaults, minimal friction, and a feature set that gets you from blank canvas to finished diagram quickly.
What does ClickCharts do best?
ClickCharts excels at the bread-and-butter diagram types that teams actually need day-to-day — flowcharts, swimlane diagrams, and simple UML sequences — without overwhelming you with obscure notation standards you will never touch.
- Drag-and-drop shape library — standard flowchart shapes, connectors, and decision diamonds are right there in the sidebar; snap-to-grid keeps lines tidy automatically.
- Smart connectors — draw an arrow between two shapes and it stays attached when you move either element, so reorganising a complex diagram does not become a line-straightening exercise.
- Multiple diagram types — beyond flowcharts, you can build org charts, network topology sketches, value-stream maps, and entity-relationship diagrams from the same interface.
- Export flexibility — finished diagrams can go out as PNG, PDF, or SVG, which covers the three most common handoff formats for documentation and presentations.
- Low learning curve — I had a twelve-step onboarding process mapped in under twenty minutes on first launch, which puts it firmly ahead of learning Lucidchart's keyboard shortcuts from scratch.
How much does ClickCharts cost?
ClickCharts is free to download and try. NCH Software typically offers a free tier suitable for personal and non-commercial use, with a paid licence unlocking the full feature set for professional or business work. Check the NCH website for current pricing, since licence tiers and bundle offers change periodically. There is no subscription trap here — the paid version is a one-time purchase model, which I find refreshing in an era where every tool wants a monthly direct debit.
Who should use ClickCharts?
ClickCharts is a strong fit for small business owners, operations managers, and developers who need to produce clear process documentation without the overhead of an enterprise diagramming suite. If your team lives inside Notion or Confluence and you just need a reliable way to export a clean PNG of a workflow, ClickCharts handles that without demanding you learn a proprietary format.
It is less compelling for UX designers producing detailed interaction flows with custom components — in that space, Whimsical or FigJam are better native Mac citizens with real-time collaboration built in. Similarly, enterprise architects managing sprawling BPMN models will quickly outgrow what ClickCharts offers and should look at OmniGraffle or draw.io instead.
Where ClickCharts wins is the middle ground: the solo consultant who needs polished diagrams for client decks, the developer who wants to sketch a database schema before migrating it, or the operations lead who documents SOPs and wants something more purposeful than PowerPoint shapes.
What are the best ClickCharts alternatives?
The diagramming space on Mac is genuinely competitive. OmniGraffle is the power-user gold standard — deeply Mac-native, scriptable, and capable of enormous diagrams — but it costs significantly more and has a steeper learning curve. draw.io (now diagrams.net) is free, runs in the browser and as an Electron app, and integrates with Confluence and Google Drive; it is the pragmatic choice for teams already in those ecosystems. Whimsical shines for collaborative wireframing and flowcharting in real time. Lucidchart is the enterprise favourite with SSO and admin controls, but it is subscription-only and browser-first.
ClickCharts sits in a comfortable niche below OmniGraffle in price and complexity, and above draw.io in polish for offline, single-user work. If you want a native Mac app that installs, opens, and gets out of your way, it earns its place in that comparison.
How does ClickCharts compare to OmniGraffle?
OmniGraffle is the undisputed champion of Mac diagramming — it has been on the platform for over two decades, supports automation via OmniJS, handles huge canvases gracefully, and integrates with macOS accessibility features in ways no cross-platform tool can match. It is also considerably more expensive and requires more investment to use well. ClickCharts asks far less of you in both time and money, and for the majority of business diagramming tasks — a process flow, an org chart, a data pipeline sketch — it delivers a result that is just as presentable. Think of OmniGraffle as the professional kitchen range and ClickCharts as a well-built countertop appliance: the job usually just needs the appliance.
