Comparison
Drawdy vs draw.io
draw.io is free forever, open source, needs no account, and never touches your files. It is also a diagramming tool first, and its live co-editing works only when the file sits in Google Drive, OneDrive, Confluence Cloud or Nextcloud.
Feature by feature
| Feature | draw.io | Drawdy |
|---|---|---|
| Your AI draws on your boards (MCP)draw.io's free official MCP server draws in the chat or opens a new editor tab, and can edit a .drawio file on your own disk; it does not save into your Drive, OneDrive or Confluence files | Local files | Yes |
| Extensions run on the boardThe web editor and Docker image load plugins only from a built-in list, which draw.io calls unsupported examples for developers; the desktop app dropped plugins in v31.1.5 | Built-in list | Yes |
| Free with no board limit | Yes | Yes |
| No account needed to start | Yes | Yes |
| Open source and self-hostabledraw.io is Apache 2.0, with a Docker image; Drawdy is not open source | Yes | No |
| Hand-drawn lookdraw.io has a sketch style you switch on; in Drawdy the hand-drawn feel is the default | Yes | Yes |
| Real-time collaboration built into the editordraw.io's docs describe live co-editing with shared cursors only when the file is stored in Google Drive, OneDrive, Confluence Cloud or Nextcloud | Via storage | Yes |
| Guests can edit from a link without an accountdraw.io sharing is whatever your storage provider offers, so link editing runs on Drive or Confluence permissions rather than on draw.io | No | Yes |
| Export to PNG, SVG, and JSONdraw.io also exports JPEG, WebP, animated GIF, PDF, HTML and its own .drawio XML | Yes | Yes |
| Technical shape libraries: UML, ERD, network, rack | Yes | No |
| Offline desktop appdraw.io ships one for Windows, macOS and Linux | Yes | No |
| Embeddable editor for your own product | Yes | No |
| Keep files in your own Drive, OneDrive, or GitHub | Yes | No |
| End-to-end encrypted snapshot linksdraw.io never hosts your files, which is a strong privacy answer of a different kind; sharing security is your storage provider's, not theirs | No | Yes |
| Sketched-shape recognitionRough rectangle in, clean rectangle out. draw.io's sketch style restyles shapes you place, it does not read freehand strokes | No | Yes |
| Presentation mode | Yes | Yes |
| Version historydraw.io keeps no files of its own, so history is whatever Drive, Confluence or Git gives you | Via storage | Yes |
What draw.io gets right
draw.io makes a promise almost nobody else in this category makes, and then keeps it. The editor is free forever under the Apache 2.0 licence, takes no account and no card, and the project's own words on storage are hard to improve on: store your data wherever you want, we cannot access it, ever. Files go to your Google Drive, OneDrive, GitHub or GitLab, your browser, or straight to disk. There is no vendor sitting in the middle of your diagrams.
For technical diagramming it is deeper than anything here. UML, entity-relationship models, network infrastructure, rack and circuit diagrams, org charts, floorplans, attack trees, dependency graphs, with the shape libraries to match. It ships an offline desktop app for Windows, macOS and Linux, you can self-host it from its Docker image or by forking it onto GitHub Pages, and you can embed the editor inside your own application. Its Confluence and Jira integration is the reason a lot of teams have it at all.
The difference that matters is what happens when two people open the same file. draw.io's repository says the editor does not support real-time collaborative editing, but its documentation describes live co-editing with shared cursors when the file is stored in Google Drive, OneDrive, Confluence Cloud or Nextcloud. Files elsewhere get none, so whether two people can draw together depends on where the file lives.
Which one should you pick?
Choose draw.io if…
- You are drawing technical diagrams: UML, entity-relationship models, network topology, rack layouts, or cloud architecture with proper icon sets.
- You want your files in your own Google Drive, OneDrive, GitHub or on disk, with the vendor unable to read them at all.
- You need an offline desktop app, or you want to self-host the editor from a Docker image behind your own firewall.
- Your team works in Confluence or Jira and you want diagrams living inside the page.
- You want Apache 2.0 source you can read, fork and keep running regardless of what the project does next.
Choose Drawdy if…
- You want your own AI, such as Claude, ChatGPT, Codex or VS Code, to draw on the board with your team: connect it over MCP and it works on your cloud boards, free on both plans.
- You want to add the feature you are missing yourself: install one from the extension marketplace, or have a coding agent build one from the extension docs.
- You want people drawing on the same board at the same time, with live cursors, from the app itself rather than through a storage provider.
- You want to send one link and have somebody start editing on it, with no account and no Drive permissions to grant.
- You are sketching and thinking rather than producing a formal diagram, and you want the hand-drawn feel by default.
- You want shape recognition, presentation mode and version history in one place, without wiring up a storage backend to get them.
- You want snapshot links that are end-to-end encrypted and that you can hand to someone directly.
What each one costs
draw.io
The editor is free forever, with no account and no card, under the Apache 2.0 licence, and draw.io does not host your files: store your data wherever you want, and they cannot access it. What is sold commercially is the Atlassian side, draw.io for Confluence and Jira, which Atlassian bills through its Marketplace (a Confluence Cloud licence also covers Jira Cloud at no extra cost), and, per its repository, a paid production version for production deployments. draw.io does not publish those prices on its own site; get the Atlassian quote from the Marketplace.
Drawdy
Free to start and free to keep using: unlimited boards on your device and three cloud boards for syncing and sharing, with no card. Pro lifts the cloud-board limit and starts with one month free; the free tier itself does not expire.

Questions people actually ask
Does draw.io have real-time collaboration?+
Yes, depending on where the file lives. draw.io's own repository states that it does not support real-time collaborative editing in the current version, but its documentation describes live co-editing with shared cursors for files kept in Google Drive, OneDrive, Confluence Cloud or Nextcloud. For diagrams that is usually fine. Drawdy runs live collaboration on its own cloud boards instead.
Is draw.io really free?+
Yes, and unusually unconditionally. The web editor is free forever, needs no sign-up and no card, and is licensed under Apache 2.0. There is no board cap, no trial clock and no feature held back. The commercial products are the Atlassian integration, draw.io for Confluence and Jira, sold through the Atlassian Marketplace, and what its repository calls a paid production version for production deployments.
Is draw.io the same as diagrams.net?+
They are the same project. draw.io is the editor and the name of the repository, drawio.com is the project's site, and app.diagrams.net is the production deployment the repository points at. You can use either address and get the same editor.
Where does draw.io store my diagrams?+
Wherever you tell it to, and nowhere else. It writes to Google Drive, Microsoft OneDrive, GitHub or GitLab, your browser's storage, or a file on your device, and the project's own claim is that they cannot access your data. That is a genuinely strong privacy position, and it is the reason draw.io has no history of its own: it never has your file.
draw.io vs Excalidraw, which should I use?+
Pick by what you are drawing. draw.io is for structured, technical diagrams with real shape libraries: UML, ERD, network, cloud architecture, and it is free forever with your files in your own storage. Excalidraw is a sketchpad with a hand-drawn feel, open source and self-hostable, with live collaboration built in and cloud boards behind its Plus tier at $7 per user per month ($6 billed yearly). If the output is a diagram somebody has to maintain, draw.io. If the output is thinking, Excalidraw or Drawdy.
