Frequently asked questions
- What is a good alternative to Miro for technical diagrams?
- flow-chart.io is an AI-native alternative to Miro for technical diagramming. Where Miro is a freeform whiteboard for brainstorming and wireframing, flow-chart.io specializes in standards-oriented technical diagrams: BPMN 2.0 process flows, C4 architecture diagrams, UML, ERD, STRIDE threat models, cloud architecture, and 11 more domains.
- Can flow-chart.io replace Miro for team collaboration?
- Not as a workshop whiteboard. Miro still leads for realtime collaboration, sticky notes, and facilitated workshops. flow-chart.io fits technical diagram jobs — BPMN-inspired process maps, C4, UML, ERD — where you want plain language → editable scene graph → SVG.
- Does flow-chart.io support BPMN, C4, and UML?
- flow-chart.io provides domain-aware generation and an advisor that can flag potential BPMN, C4, and ERD notation issues. Generated drafts still require user review and are not standards certifications.
- What export formats does flow-chart.io support?
- SVG (vector, scalable), PNG at 2× and 4× resolution, PDF (print-ready), JSON (the full typed scene graph for re-import), and Mermaid (.mmd). Miro exports to PDF, PNG, CSV, and Miro's proprietary format.
- Can I use flow-chart.io without installing anything?
- Yes. flow-chart.io runs entirely in the browser — no installation, no desktop app, no plugins. Create an account, describe your diagram, and start editing in under a minute.
