draw.io is the world's most widely used diagramming application and it's free to use and deploy yourself. Since 2005, we've been building diagramming software with one mission: provide free, high quality diagramming software for everyone. Your data stays yours. We will never lock you out of your own diagrams. Your files stay with you , not us. Free and open. The draw.io editor is Apache 2.0 licensed. No artificial scarcity, no Enterprise tier for SSO.

No lock-in. When companies pay us (through our Atlassian integrations ), it's because we add value, not because we've trapped them. You always control your data. Independent and sustainable. We're not VC-funded or chasing growth-at-all-costs. draw.io Ltd (UK) and draw.io AG (Switzerland) are private companies focused on building great software, not inflating valuations. Privacy-first. The free app.diagrams.net stores nothing on our servers, your diagrams stay on your device or your chosen cloud storage . draw.io AG · Altenhofstrasse 45, 8008 Zürich, Switzerland · CHE-210.604.548
