Flowchart Editor
Zero-dependency flowchart and diagram editor that works on desktop, phone, and tablet.
About Flowchart Editor
Draw a flowchart by dropping shapes onto a canvas, connecting them with arrows, and labeling each node — no account, no install, no dependencies standing between you and a finished diagram. It runs entirely in the browser, so the same file you open on your laptop works just as smoothly on your phone during a meeting or on a tablet at a whiteboard session.
The editor suits anyone who needs to sketch a process quickly: a developer mapping out an API flow, a manager drafting an onboarding checklist, or a student laying out a decision tree for a project. It belongs comfortably in the broader productivity space alongside note-taking and planning tools, though its focus stays tight on visual structure. If your thinking starts more organically — branching ideas rather than linear steps — Mind Map covers that territory well.
Built on the open-source DgrmJS library under the Apache 2.0 license, it works best on desktop where a mouse makes precise connection-dragging easy, though touch controls are fully supported.
