This question often comes to me from time to time literally. So here's me answering it in a casual way. I use Claude for everything and have made apps and published on google play. $20 plan is doable (although not as generous as cursor) but you can do full app with claude code. I always say that it's about driver not about the car. You have to understand how to work with any AI agent, You can start with one, like cursor for example and use it for a month etc. You will understand whether it's good with your workflow and helps you become productive or not. So if I like Claude, then its not necessary that you also like Claude. I tried many different AI tools and still try new tools on/off, but claude code is what i have become extremely comfortable with and I now know what things Claude lack in, and what things Claude is good at and so on, so I can work with it very easily and remain very productive. If you keep switching tools every few days just because some YouTube video called it as "insane" or "chatgpt killer" or "other tools are dead" and what not, then you are basically wasting time, tokens and money. You need to work with one for starting and give it a bit of time to polish it more as per your taste and style and workflow, then you can get a lot of productivity out of that. So it can be Antigravity, Claude Code, Cursor, OpenCode, Codex or ollama or whatever. Just pick one and start exploring it for at least a month and see how that works out for you.
