How to choose

Which platforms does it need to run on?

Choose a tool that supports the places you work. The board lists web, macOS, Windows, API, Linux and iOS support.

A web option can suit browser-based work, while desktop or mobile support matters when your workflow depends on a specific device.

Should you start with a free plan or trial?

Start with a free plan when you need ongoing basic access; use a free trial when you want to evaluate paid features before subscribing.

The board separates free-plan availability, free-trial availability and the paid-from price. flow-chart.io lists paid plans from $19 per month.

Which diagram features should you compare?

Compare flowchart templates, real-time collaboration, offline access, import and export formats, and the diagrams allowed on a free plan.

These fields show whether a tool fits solo diagram work, shared editing or workflows that need files moved between formats.

Do you need an API or open-source code?

Use the API mark when software needs to connect with other systems through a public interface. Check the open-source mark when code access or licence terms matter.

The board displays both marks so you can factor integration and code availability into the choice.
