I’ve been using Greta to build full-stack, no-code applications and websites with just AI prompts, and my experience so far has been very positive. In just a single day, I was able to create a fully functional app complete with features, analytics, a dashboard, and a landing page.

What I liked:

Speed & Ease: Generating a working app from scratch using prompts was fast and straightforward. The process is smooth, with minimal manual intervention needed.
Modern Design: The landing page looked professional, with a fresh design, on-theme color palette, and impressive 3D animations. Everything was responsive and worked well across devices.
Feature Completeness: All core app features functioned as expected and the analytics/dashboard modules were useful and customizable.
Responsive Team: The team behind Greta is highly responsive, open to feedback, and clearly focused on rapid product improvement based on user needs.
Areas for Improvement:

Project File Limits: There’s currently a limitation on the number of files you can have per project. Once you cross this threshold, some agent functionality is affected. I have 5-6 projects that hit this limit and am waiting for the upcoming Agent feature update, which promises to support more files per project.
Scaling: While the core product is solid, scaling up complex or file-heavy projects is still a challenge until the new Agent feature is released.
Overall:

Greta is a strong choice for quickly building modern, feature-rich web apps without code. The design output feels current and professional, and the team is actively working to address its current limitations. Once the file/project/agent constraints are resolved, Greta will be even more powerful for larger-scale projects.

Rating:
Highly recommended for rapid prototyping and small-to-medium projects; looking forward to improvements for larger projects.
