Use Diagrams to create and share flowcharts, mind maps, org charts, network, and other diagrams. The app saves your diagrams in the browser, which means your data stays on your device and is not sent to any servers or services.

My recently released MJS Diagram library enables developers to add diagramming to their web apps. My own work inspired me to “dogfood it” and create a full-fledged diagramming app. It is out now, and you can use Diagrams to create and share flowcharts, mind maps, org charts, network and other diagrams. ✅ No servers, no logins — everything is local and organic. The app saves your diagrams in the browser, which means your data stays on your device and is not sent to any servers or services. It also means there’s no need to create user accounts, login, and you won’t get any spam from me (as I have no idea who you are :) On the downside, this also means that your diagrams are not accessible by you from other devices. And they are also not backed up anywhere. But you can easily mitigate this by saving diagram files to your cloud storage and importing them on other devices. ✅ It’s an app. A Progressive Web App. In addition to using Diagrams in the browser you can install it on your device and use it as any native app (provided you visit it from a compatible browser). ✅ It is also a demo and an open-source one. The app is a real-world example of MJS Diagram integration and complete source code for it is available on GitHub under the MIT license. Feel free to explore and/or fork it! ✅ Check it out! Check out Diagrams, create and share your… uhm… diagrams and let me know what you think! And if you know anyone who may find it useful, don’t forget to share the link with them. Thank you ❣️

@ailon Congratulations on your launch! Good luck :)

Congrats! I like your product. Nice UI and solve an important problem! Can I embed the chart created in your product into Notion page?

@naoto_shibata_morph pressing the share button generates a png image that you can insert anywhere you want. As this is a local (client-side) app, there's no way to embed a "live" diagram as it's only stored on the device where it was created.

I love the approach you've taken to ensure user privacy and data security by keeping everything local. This is a very refreshing change in the world of web apps where data sharing and harvesting have become a major concern. Also, that seems really stable, so kudos for creating the library, too. Must have been a lot of work. Congratulations and keep it up!

@wintoniak yes, the library was a lot of work. The app took about a week. Which I guess is the point of the library 😅
