BPMN Studio vs bpmn.io
bpmn.io gives you the canvas; BPMN Studio gives you the canvas plus an AI that fills it. bpmn.io is the free, open-source home of bpmn-js — the BPMN rendering and editing toolkit used across the industry (including by BPMN Studio and Camunda Modeler). BPMN Studio uses that same engine but adds the step bpmn.io doesn't have: generating the diagram from a plain-English description.
Short answer. Choose bpmn.io if you want a free, open-source canvas and you'll model everything by hand (or you're a developer embedding bpmn-js). Choose BPMN Studio if you want the same quality canvas but with AI generating the first draft from your description.

When to choose BPMN Studio
- You want AI to translate your words into BPMN, then edit on a real canvas.
- You want saved diagrams, history and export management tied to an account.
When to choose bpmn.io
- You're a developer embedding the bpmn-js modeller in your own product.
- You want a free, open-source, self-hostable canvas and will model manually.
Since both speak BPMN 2.0 XML, you lose nothing by starting in BPMN Studio and continuing in bpmn.io later. Generate your first diagram free, or read what is BPMN and the Best AI BPMN generators 2026 comparison.
Frequently asked questions
Is BPMN Studio built on bpmn.io?
BPMN Studio renders and edits diagrams with bpmn-js — the open-source library behind bpmn.io and Camunda Modeler. The difference is the AI layer: BPMN Studio generates the BPMN 2.0 from a plain-English description before you edit it on that canvas.
Is bpmn.io free?
Yes. bpmn.io and its bpmn-js toolkit are free and open source, but they have no AI generation — you model manually. BPMN Studio adds AI generation and account features, with a free tier and paid plans.
Can I move diagrams between them?
Yes. Because both use standard BPMN 2.0 XML, a diagram generated in BPMN Studio (exported on the Max plan) opens in the bpmn.io demo modeller and vice versa.
