What this free online flowchart maker does
Wikawe Canvas is a free online flowchart maker and diagram tool for process maps, architecture diagrams, mind maps, UML, and network drawings. Pan and zoom an infinite canvas, connect shapes with smart connectors, import Mermaid flowcharts, and export PNG, SVG, PDF, JSON, or Mermaid. Documents auto-save in IndexedDB on this device and are not uploaded to wikawe servers.
Use it when you need a no-signup flowchart maker online: templates you can edit, keyboard shortcuts, layers, and exports of canvas contents rather than a screenshot of the UI.
When to use an online flowchart or diagram maker
Product and engineering diagrams such as user registration, e-commerce checkout, CI/CD, and software architecture.
Mind maps for brainstorming, UML class sketches, and turning Mermaid graph TD snippets into editable shapes you can restyle and export.
Tips for better flowcharts and diagrams
Use elbow connectors for flowcharts and keep labels on edges for Yes/No decisions.
Export JSON as a backup if you switch browsers — local save stays on this device.
If you need a related job next — cards in Wikawe Design, PDFs in PDF Workspace, or image export via Smart Image — open those tools from this page. Chaining keeps your files on your device throughout.
Privacy and quality
Editing, auto-save, Mermaid conversion, and export run in your browser. Nothing is sent to wikawe servers for the standard workflow.
Mermaid import supports flowchart graphs. Sequence, class, ER, Gantt, pie, subgraphs, and style statements are not converted.
