I purchased the Tier 3 package, and at first, I was really impressed. The tool is promising and intuitive, and I genuinely love the UI Greta produces. It looks much better than what I have seen from other competitors. Rough ideas are translated surprisingly well into a functional-looking web app, which initially felt magical.

But unfortunately, that is where the excitement ended.

I invested over a dozen hours (and almost all my monthly credits) trying to build a simple Task Manager app, and despite multiple fresh starts, I failed to create a functional app that properly stores data in Supabase.

My first attempt created a great app, but it saved all data only in local browser storage.

When I tried to port it to Supabase, things got messy. Data was inconsistently stored between local storage and Supabase.

Trying to fix problems often ends in loops. Greta tells you it is fixed, but it is not. It is a fast way to burn credits.

New bugs often appear while trying to fix issues. Greta sometimes kills functions that worked before, completely redesigns the app, or removes previously working features. You constantly need to check your whole app again to see if parts are broken or missing.

Other frustrations included:

Preview not showing up at times

Commands sometimes ignored unless I logged out and in again

Login issues. I did not receive the login code to my main email address, even after disabling all spam filters. Support eventually solved this, but only by suggesting I switch to a Gmail address.

I really wanted this to work, but after all the time and effort, I was left with no usable app that properly stores data in Supabase.

Greta has great potential, and I hope future updates will make it stable enough to build real apps. Right now, it is too unreliable and frustrating for serious use, which is why I give it only 2 stars.
