not a whiteboard app to collaborate online, but a diagram drawing tool
While it isn't the same as Miro (and tbh no other tool comes as close to what Miro does so far) but it's a good "start" which is fully free. Collaboration via Google Drive/Workspace works fine, but again not a proper Miro replacement but the best we got so far.
Excalidraw is an open-source whiteboard tool that lets you easily sketch diagrams that have a hand-drawn feel to them. Available directly online as a web app and also through CodeSandbox to easily see how the code works, and the app is available for self-hosting.
Takes security seriously, sleek and minimal design, a delightful product that does exactly what it promises to do.
Incredible alternative, works very well. It even saves whiteboard as a local file.
But unfortunately if you like the convenience of auto-saves, or storing the files "inside the app itself" so that next time you can just launch the app & select the thumbnail in a couple of clicks without needing to touch File Explorer (like Miro), you're going to need the Excalidraw+ subscription; which has a pricing that is just overkill for personal/hobbyist use.
Click and play : Simple and encrypted.
Also, it is open-source and can be installed on your server.
