Access Obsidian from anywhere using a browser by self-hosting it

Ever since I started exploring alternate options to take notes, I've been constantly going back and forth between Notion and Obsidian. They're both excellent apps that offer a host of functionality apart from just taking notes. You can use them to create to-do lists, wiki pages, planners, etc. You can even map content from different notes and link them together. The possibilities are plenty. However, by default, Obsidian can only be accessed via the app. While that is fine for most people using their own devices, what if someone wants to access their Obsidian notes using a device that's not theirs? It could be a friend's phone, a public computer in a hotel, or their office laptop.
