Firebase studio is great, it has a great future, it reminds me to your ai.dev builder (which is even better but only frontend sadly)
But the issue relies when you are working consistently and scaling your app then issues start to appear with frequent errors due your context being too big, even disabling codebase indexing makes that the references kill Gemini.
The context it has is way superior to any other, if you can really fix that, which is vibe coding through Gemini it has a great future ahead. If not, it will be hard to scale up.
I really loved, but loved the UI, UX but in the middle of the project i had to move away to vscode + ai, to really keep working in my codebase.
As well another area of improvement is the implement button to be clicked, create a flow to work like your ai.dev builder that you agree with the AI and then just implement, flow become way smoother.
Hope you can fix it asap so i can move back to your Firebase Studio to keep building, by the way if you need deep beta testing, i am in to move my codebase and start throwing rocks to the system to see how it handles and provide feedback.
Keep improving it!!
