I made an app for pulling data for UK postcodes from the postcodes.io (http://postcodes.io) API.

The process was a little convoluted.
1/ Used ChatGPT Agent to digest the API docs and come up with an HTML/CSS/JS MVP which I tested and refined.
2/ Copy pasted the code into Lovable along with a style guide to work on the interface.
3/ Committed the Lovable app to Github and synched the repo with a host (Netlify) and my IDE (Antigravity).
4/ Debugged and worked on the code in Antigravity with Gemini 3.
5/ Created the background animation in Claude and then integrated it.
6/ Changed API handling from the front end (CORS) to a backend serverless Netlify function to make everything more robust.
The majority of work was in Antigravity, which, because of Gemini 3, is jaw-droppingly good.

First post here! Hello Contra. This is a great platform, I joined today and I'm blown away.
I'm working on a little app that pulls data from the Wayback Machine for any given URL. It's designed to predominantly report on site structure and robots.txt changes but I have ideas for bringing it forward.
I built it first in JS, using Deepseek and Kimi to bounce ideas off each other, then pasted my code into Lovable to get to a better designed UI.
There's work still to be done but I'm pretty chuffed with what's been achieved. All feedback's welcome.
