           | 
           | With LLM apps, there is none of that. You created the app so

           | you.
           | 
           | The modern software paradigm is building software that covers
           | as massive of a solution space as possible, so as many users
           | as possible have a problem that is covered by that space. You
           | end up having to make lots of compromises and unintuitive
           | steps to cover all the bases.
           | 
           | LLM apps cover your problem space pretty much perfectly,
           | without anything more.

         | like half an hours to get what you want.
         | 
         | The only downside was not being able to access the apps from
         | other devices, so I ended up creating a tool to make them
         | online accessible and sync the data, while using the same
         | localStorage API. It's actually pretty neat.

             | HTML file I was replacing localstorage calls to calls to
             | the API automatically, via a script that was doing a simple
             | search-and-replace on the file. I was also assigning a
             | custom subdomains via nginx to each html file, so that it
             | could have the max 10MB storage that localstorage can have.
             | 
             | After a while it became clunky doing things with separate

         | The frontend, however, is a completely different story.

         | is like building a house out of wine glasses."
         | 
         | AI and frontends are a natural fit, there is way more tolerance
         | for brittleness 'move fast break things' on the frontend as the
         | consequences of bugs are far less severe.

         | Software is written to offer a massive solution space, so that

       | 
       | This is a good approach. Developers can interact with Claude
       | directly while BaaS platforms like Saasufy can host the backend

       | This approach could finally support production-ready apps, not
