Vibe coded CRMs do exist. They are not open to the public though, as they are just used by the company that built them tailored to their needs is all.

Same with more complex systems: entire shop systems with payment integration, ERP and all – heavily supported by LLM code tools with a 3-10x productivity boost, just done by the CTO and no additional developers needed. They exist, the shop greets it’s customers and all you see is Vue and Tailwind as the tech stack where Shopify could’ve been. It’s now completely owned by the company selling things (they just don't sell the software).

This has been similar to my own personal experience. I've generated a number of scripts and browser extensions to do various things perfectly fitting my use cases, but they're far too niche to be worth publishing.
