Cacoo, by Nulab, is an online diagramming tool for flowcharts, wireframes, network diagrams, and org charts with real-time team collaboration.
Teams and organizations that need a browser-based, collaborative diagramming tool for flowcharts, org charts, UML, and ERDs — from small project teams working on the free plan up to enterprises needing SSO and centralized access controls.
An online canvas with template libraries and shape stencils for flowcharts, org charts, UML, wireframes, and database/ER diagrams, real-time multi-user editing with in-app video chat and follow mode, dynamic charts/tables, a 'Code-to-graph' feature to generate diagrams from structured code, Microsoft Visio file import, and export to PNG/SVG/PDF/PS/PPT.
Diagrams live on a shared, infinite web canvas built from Nulab's own diagram engine; multiple users edit the same board simultaneously with live cursors and version history, and diagrams can be embedded elsewhere or exported, with paid tiers unlocking more sheets, richer export formats, and enterprise security/admin controls.
