If you’re a developer sketching architecture or brainstorming ideas and prefer a cozy, hand-drawn aesthetic, go for Excalidraw. Its charm lies in its simplicity and ability to work offline, making it great for quick, unpolished sketches. However, avoid it if you need high-fidelity visuals or a comprehensive design tool.
On the other hand, if you're a Mac user who thrives in a keyboard-driven environment, Rectangle is the right choice. It excels at efficiently snapping windows with just shortcuts, enhancing your workflow. Just keep in mind that it's limited to Mac, and if you’re looking for advanced window management features, a paid Pro version is necessary.
