Testing the limits with just free tier of Antigravity, Codex, Cursor

For the last 3 days I was working on this web tool that takes in a website URL and returns the "LLM friendliness" of that site.

Meaning how would an LLM see that site, that whole Generative Engine Optimization thing but in plain simple English without the technicalities.

I wanted to see if I can build it with just the free tiers of vibe coding IDEs. I started working in antigravity and was using the Codex extension.

I have 4 different Codex accounts and I hit the limit on all of them. By then the backend was up and running. I handed over the work to the inbuilt Gemini and Claude models in Antigravity, By the time front end was done and I lit the limit on Antigravity and Cursor (I shifted to Cursor as I hit limits on Antigravity).

Hitting limit on the IDE sucks more than the models tbh

During all this I gave all my models a set of skills for the design part, u can find them here:

I tried using Stitch for the UI, but it sucks, I tried alternative ways of prompting and all, but it just spits out AI Slop (if anyone has this whole Stich thing figured out, pls help me TT TT)

I also used a security skill, was a great help as I found out numerous issues. I used my 4th (and last) codex account inside VS Code to run the security scan and fix the vulnerabilities.

here's the skill: https://github.com/raroque/vibe-security-skill

(shout out to the creators of all the skills mentioned)

And finally I pushed my code to git and used Render for hosting.
