In their own words
sysdraw
Sysdraw is a browser-based editor for system design and architecture diagrams built on an infinite canvas. Users can describe a system in plain English to generate an editable diagram, then refine it through chat or prompts applied to a selected canvas area. Diagram options include flowchart, sequence, class, ER, and state diagrams, plus a BPMN 2.0 palette. A searchable icon library covers services, queues, databases, caches, and gateways; connectors snap to anchors and route around obstacles. Mermaid imports support flowchart, sequence, class, state, ER, gantt, pie, and gitGraph diagrams. Collaboration includes live cursors, selections, comments, mentions, and email invitations with view, comment, or edit roles. Users can publish view-only links or embed live diagrams in Notion, blogs, and READMEs. Local-first auto-save works offline without signup; signing in enables cross-device sync. The Free plan costs nothing, Pro costs $6 a month, and Ultra costs $20 a month.
