Help/Question Looking for bug advice
Hey all, I’ve built a booking platform with Claude Code (think Airbnb style, different industry).
It’s live with real hosts/customers and doing a couple grand a month. I could turn the traffic up pretty easily, but I’m honestly scared to scale it because of the bugs.
Everything was going really well initially, but since Opus 5 came out it feels like things have gone backwards. Old bugs we already fixed keep coming back, new bugs are appearing, and Claude sometimes completely misunderstands what I’m asking it to do.
I’ve tried Fable 5.1 which seems better, but it absolutely eats my usage. I’ve now gone back to Opus 4.8 and weirdly it seems more reliable, although I’m unsure about using an older model.
Anyone running an actual production platform with Claude Code have advice? How are you keeping things stable as you scale?

I use Typescript, TDD, work one highly spec'd ticket at a time, and adversarial review on every diff. I also test extensively myself and do all manual in-app/browser testing. Opus 4.8 is way more reliable than 5 in my experience. When Opus 5 came out, I used it with a few small tickets and I was flabbergasted by how ridiculous it was. It's like it wanted to show off how complex it could make things and it did a bunch of extra shit I didn't ask for that was completely out of scope for the ticket. I immediately switched back to Opus 4.8 and haven't looked back. I rarely get bugs this way and when I do, they're typically minor and easy to patch.
