If you're an API developer or an open-source enthusiast looking for a straightforward, cost-effective solution, choose Hoppscotch. Its offline capabilities and cross-platform support make it ideal for local development, although you'll need to sacrifice some advanced features and integrations.
On the other hand, if you're focused on personal organization or project management and want a customizable environment for your notes, go with Obsidian. Its local storage ensures privacy, and the flexibility of plugins lets you tailor the experience to your needs. Avoid it if real-time collaboration or cloud-based access is critical for your workflow.
