Greeting, Sumolings!
Her is my "Greta App" Review – my honest feedback after intensive testing, and developing 2 apps with it. (Well... At least the base core functionalities of them anyway)

We’ve been using the Greta app to prototype and scaffold out internal admin tools and client-facing web apps. After building two complete app bases inside Greta, I can say with confidence: this platform has serious potential, but it’s still in an early and fairly unstable phase.

I consider myself quite skilled as a prompt engineer—we work with AI in our own development teams, and I understand how to structure precise instructions for maximum clarity. Even so, Greta regularly fails to follow clear, detailed prompts. Despite this, I was still able to generate functional baselines for both apps with the help of my team—but it took far more "trial and error" than expected.

Bugs and Incomplete Integrations:

There are numerous bugs, especially around:

* Menu integration for modules**: even when explicitly prompted, Greta does not wire new modules into the sidebar navigation. You always have to manually prompt again just to get working links.
* Supabase and GitHub integrations** do not really work. I’ve never been able to push to GitHub successfully, and neither Pankaj nor Praveen have responded to support emails (despite being listed as contacts).
* Calendar views are unreliable**: even with clear, annotated image samples and highly structured prompts, the layout often renders incorrectly (box alignment, time positioning, overlapping class handling, etc.). It required multiple follow-up prompts, and eventually we had to assign it to one of our developers to clean it up manually.

Burning Credits, TIme and Frustrations:

Greta is quite credit-hungry. I burned through a huge amount of credits trying to get one visual alignment corrected, and still had to hand it off to a developer. If you’re using Greta with any ambition of pixel precision or UI refinement, be prepared to run out of credits fast unless you babysit every step and break your prompts into very small units. Several occasions when launcing a new module prompt for development: It takes the credits, but then suddenly the progress just stops, and it reverts back to the previous stage without any notification or explanation from the AI on what happened.

What Works:

* The modular structure conceptually works. You can break down your app by functionality (e.g., attendance module, calendar, messaging) and build each part separately.
* You can definitely get to a **working baseline** if you’re persistent and willing to prompt around Greta’s shortcomings.
* Prompt chaining works **to an extent**—but it often ignores or misinterprets dependencies unless you manually ensure that state and navigation are reconnected afterward.

Why I Upgraded (Despite All This)

I initially subscribed at Tier 3 but upgraded to Tier 4 because I **believe in the vision**. This could become an incredibly useful product for fast prototyping and scaffolding production-grade tools. But right now, it’s more of a developer assistant, than a fully autonomous builder.

My suggestions for Improvement:

* Fix GitHub and Supabase integration or remove them until stable.
* Improve prompt interpretation, especially when given image references and UI layout constraints.
* Stop generating module pages in isolation— menu connections and settings integration must happen as part of the module build, not as a separate prompt.
* Add a debug or dry-run mode to preview layout generation before burning credits.

Final Verdict (For Now)

Greta has promise—and with ongoing investment it could be a long-term tool in our stack. But as of today, it’s a bit incomplete and inconsistent. It needs refinement, reliability, and responsiveness to become a dependable builder. For now, we treat it as a starting point—not a hands-off solution.
