       | No persistent storage and other limitations make it just a toy

       | Todo apps, gym logging apps and whatever other simple thing.
       | 
       | no external API access currently but when that's available or app
       | users can communicate with other app users, some virality is
       | possible for people who make the best tiny apps.

         | apps, that would work offline with localStorage. It's not that
         | there aren't good options out there, but you can't really
         | customize them to work _exactly_ how you want. Also it takes
         | 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.

       | 
       | 2) professional tools that target "serious" developers who are
       | already working on bigger/more complex code bases
       | 
       | Interesting that Claude is going after both. 1) with this new
