If you're a developer looking to sketch out architecture or brainstorming ideas quickly, Excalidraw is the right choice. Its hand-drawn aesthetic is appealing for informal sketches, and being open-source allows for local data storage, making it a secure and flexible option. It’s perfect when your focus is on collaboration and ideation rather than on creating polished visuals.
On the other hand, if you want to design and publish real websites without diving into code, go for Framer. Its strength lies in creating interactive and visually appealing marketing sites or portfolios, especially if you appreciate strong animations and pre-built templates. However, be prepared to pay for custom domains or scaling, and avoid it if your project requires more intricate functionalities or control over the underlying code.
