AI Workspace for Diagrams & Collaboration
Want to use Visio online for free? The web version bundled with most Microsoft 365 plans stops at viewing and basic edits - the full editor is paid. Cloudairy gives you AI diagrams, templates, and real-time collaboration free in any browser.

You can use Visio online today: Microsoft offers Visio for the web, and the version included with most Microsoft 365 plans covers viewing and basic editing. The catch is that the full editor and complete stencil library sit behind paid Visio plans, sold per user - so most people searching for "Visio online free" end up at a paywall.
Cloudairy is the free online way to get the rest: an AI-native editor that generates flowcharts, ER diagrams, UML, and cloud architecture diagrams from a plain-text prompt. It is free to start in any browser on Windows, Mac, Linux, or Chromebook, with native AWS, Azure, and GCP icons, templates, and unlimited team members.
Verdict: Both are free ways to diagram in a browser, but they stop at different points. Visio for the web's free tier is a viewer with basic editing - great for reviewing .vsdx files, not for building diagrams. Cloudairy's free plan is a full editor: AI generation, templates, native cloud icons, and real-time collaboration with unlimited members. If you want to create diagrams online free - not just open them - Cloudairy is the stronger choice.
Describe your diagram in plain text. AI generates it instantly.
Edit any diagram visually. No code syntax required.
12,000+ icons including AWS, Azure, GCP, and Kubernetes.
A viewer with light editing. Visio for the web is real: sign in with a Microsoft account, open .vsdx files, add comments, and make basic edits. The version included with most Microsoft 365 plans is enough to review a colleague's diagram or tweak a label without buying anything.
It is not a free full editor. Building diagrams with the complete shape and stencil library, advanced formatting, and the desktop feature set requires a paid Visio plan, sold per user. That is the wall most "use Visio online for free" searches run into.
So treat the free Visio web tier as what it is - a companion viewer for people who already have Visio files. When you need to create diagrams yourself, a genuinely free online editor like Cloudairy picks up where it stops.
The free tier of Visio for the web stops at the basics: a limited set of shapes compared with the desktop app, no complete stencil library, and editing designed for touch-ups rather than building diagrams from scratch.
Anything heavier sits behind paid Visio plans, sold per user: the full web editor, the complete stencil and template library, and advanced formatting. And on a Mac or Chromebook the Visio web app is your only option either way, because the full Visio editor ships as a Windows-only desktop app.
That trade-off is fine for organizations already paying for Visio. If you came here to diagram online free, it means the Visio web app stops exactly where your work starts - which is the gap Cloudairy's free plan fills.
Creation, not just viewing. Cloudairy's free plan includes AI text-to-diagram: describe a flowchart, network diagram, or AWS architecture in plain English and get a fully editable diagram in seconds - 25 AI credits per month at no cost, straight from any browser.
It also covers what the free Visio web tier reserves for paid plans: a full visual editor with templates and 12,000+ shapes and icons, including native AWS, Azure, GCP, and Kubernetes icons for cloud architecture work - plus real-time collaboration built in.
And your existing Visio files are not stranded: import .vsdx diagrams into Cloudairy, or have the AI recreate one from a short description, then keep editing online with your team - no Visio license required.
Stay free as long as 3 boards and 25 monthly AI credits cover your work. The free plan already includes real-time collaboration and unlimited team members, so inviting colleagues costs nothing - everyone edits the same board live, in the browser.
Upgrade when you need more room: Pro at $8 per member per month adds more boards and AI credits for growing teams; Business at $16 per member per month adds advanced admin and security controls. Either way it is still a fraction of per-user Visio plans - and everything stays online in any browser, with no license keys to manage.
Pro tip: Many teams keep Visio for a few legacy or CAD-heavy files while moving day-to-day diagramming to Cloudairy for AI generation, real-time collaboration, and browser access - so the whole team can contribute, not just Visio license holders.
