I've been coding for over 10 years, and vibecoding to speed up development has intrigued me for a while now. I've tried most of the vibecode tools on the market, and Greta is by far my favorite. It can build a great looking, functional app with literally a few sentences and a click. From there, you can modify and build on the features, interface, etc. It works incredible well, and I'd say the accuracy in executing incremental steps/improvements is at 90%. It can still get confused at times, and I wound up burning ~150 credits on 2 simple issues that I expect Greta to catch much earlier in the debugging process as they continue to improve and evolve the tool. I haven't tried any payment integration settings, but the Supabase connections work incredibly well, as do the Github connections. There was also a handful of times where it looked like it was doing something, but after completed it hadn't made any changes (though credits were deducted) - but I'd say only 5-6 times out of ~80 so far. An easy way to edit things by hand without needing to use credits each time (to have the AI do it) will also make it much more powerful. I'm still giving a 5-taco review despite these (fairly small) hiccups because the platform is still new so glitches are bound to happen, but it's incredibly solid as-is, and I expect it to continue improving over time. Highly recommended, excellent tool.
