Try doing anything real with Lovable and welcome to the error loop. Has a lot of potential but Lovable does not seem to be ready to produce real apps with multiple pieces that need to work together without getting stuck in error loops. Disappointing.

It works for me. Give it another go, maybe try using a different browser.

Great UI and support, works perfectly. Most affordable rates for GPT-4 that is way more powerful than GPT-3.5

I asked it to generate simple and more complicated code, from scratch or fixing. Planning on trying it out more in the future, as it could be of great help.
