If you need a virtual whiteboard for quick sketches or brainstorming sessions, Excalidraw is your best bet. Its charming hand-drawn aesthetic suits developers sketching architecture or teams needing a low-fidelity space for brainstorming. As an open-source tool that works offline and keeps data local, it's perfect if you value privacy and self-hosting. However, don’t choose it if you’re looking for polished visuals or a comprehensive design tool.
On the other hand, if you’re focused on managing photos and videos with a desire for privacy and full control over your data, then immich is more suitable. It's a high-performance solution for tech-savvy users who can handle self-hosting setups. Just be aware that it lacks the extensive integrations offered by cloud solutions, making it less ideal if you're accustomed to using a variety of online tools. Choose immich if privacy and performance are your top priorities, but skip it if you're not ready to set up self-hosting.
