The short answer
Keep Excalidraw if you want a free, open-source canvas to sketch with others in real time, in a hand-drawn style. Use flow-chart.io when you want a finished-looking flowchart or process diagram from a description, with decisions, loops and an optional notation preset (ISO 5807 flowcharts, BPMN 2.0, UML activity or C4), that you can refine in words and export to PowerPoint or Mermaid.

Where Excalidraw is the better choice
- Live whiteboarding: several people sketching on the same canvas at once.
- Exports on the free plan: PNG and SVG cost nothing.
- Open source under the MIT license, so you can self-host or embed it.
- The hand-drawn look, which signals "rough idea" in a design discussion.
- Freeform drawing that is not a diagram at all: wireframes, annotations, doodles.
Where flow-chart.io is the better choice
- You start from a description, not a blank canvas, and get the layout done for you.
- Decisions come out as diamonds with labeled exits and loops are routed around the chart, as in the example below.
- Notation presets for ISO 5807 flowcharts, BPMN 2.0, UML activity diagrams and C4.
- Refine by describing the change ("add a rollback step") instead of moving shapes by hand.
- Pro exports SVG, PNG, PDF, native PowerPoint shapes, Mermaid and JSON.
Example: the kind of diagram flow-chart.io is built for
Using both
Because flow-chart.io Pro exports Mermaid and Excalidraw imports Mermaid, you can generate a structured flowchart here and carry it into an Excalidraw canvas for a workshop. flow-chart.io does not import .excalidraw files; to go the other way, describe the process or paste its steps.
Frequently asked questions
- Is Excalidraw free?
- Yes. Excalidraw is open source, and Excalidraw+ has a free plan. Its paid Plus plan is listed at $6 per user a month billed yearly or $7 billed monthly.
- Can flow-chart.io import Excalidraw files?
- No. Describe the process or paste its steps and flow-chart.io generates a new, editable diagram.
- Does flow-chart.io have real-time collaboration like Excalidraw?
- No. You can share a read-only link to a diagram, but there is no live multi-user editing. If that is the main need, Excalidraw is the better fit.
- Is flow-chart.io free?
- You can generate a preview free without signing up. A free account gives 4 AI credits a month (one standard diagram), saves 1 diagram and shares it as a read-only link. Downloads and unlimited diagrams are part of Pro at $9/month; see the pricing page for details.
