diagrams.net

What diagrams.net does

diagrams.net, operating under the brand draw.io, is a privately held, independent software company founded in 2005 and headquartered in Northampton, United Kingdom (with US and Swiss/EU legal entities draw.io Ltd and draw.io AG). The company builds a free, open-source diagramming platform distributed under the Apache 2.0 license, offering a web application (app.diagrams.net), a downloadable desktop application (get.diagrams.net), and native integrations with Google Workspace, Microsoft 365, Atlassian Confluence/Jira, GitHub, VS Code, and Notion. Its technology stack centers on a web-based editor with real-time collaboration via shared cursors, a privacy-first architecture in which users bring their own storage (local or third-party cloud), and backwards-compatible file formats dating back to 2005. The product also exposes an embeddable viewer (viewer.diagrams.net) that allows interactive diagrams to be placed inside any third-party application via iframe.

The platform serves a horizontal user base of developers, DevOps engineers, technical architects, IT professionals, and teams that need professional-grade diagramming for software architecture, technical documentation, and workflow visualization, with claimed reach of 100M+ users worldwide. The business model is fully freemium: no account is required, no pricing tiers exist, and there is no enterprise SSO SKU; the company explicitly states it is not VC-funded and is privately focused on building good software rather than maximizing valuation. Distribution is product-led and organic, relying on developer communities (GitHub Discussions, Stack Overflow), SEO, documentation, and deep embedding within partner platforms to drive adoption at effectively zero customer acquisition cost.

Operationally, diagrams.net runs with 1–10 employees, supported by founder Gaudenz Alder, and operates without disclosed revenue, funding rounds, M&A activity, or external institutional investors. The corporate structure spans draw.io Ltd and draw.io AG, and the company has maintained continuous operation for 20 years with backwards compatibility preserved throughout, signaling long-term product stewardship over growth-stage monetization.
