Does anyone know a alternative to Miro?

Mural, FigJam by Figma, Lucidspark by LucidChart, etc..

Yeah I think Microsoft whiteboard is prefect alternative

Canva whiteboards!

If you're working exclusively with folks in the Apple ecosystem, don't forget about Freeform! Can't beat the price…

An alternative to Miro that we’ve found effective is FigJam from Figma. It’s great for collaborative brainstorming and diagramming, with a similar feel to Miro but often smoother if you're already using Figma. Another good option is Whimsical, which is simple, intuitive, and ideal for flowcharts, wireframes, and mind maps.
