The most common way vibe coding will kill your application is by over complicating things

First way it will over complicate thing is by having too many connection points between front end and back end and communication layers

Another is it go for the most overkill option and keep trying to build it

Like if you’re creating a form SaaS,

Instead of having the whole form as a Json object which can then be rendered as a form

It will create a mess that has too many entities too many IDS to sync and very complicated connections with each other which end up leading to errors

It will create a lot of unnecessary sync operations which add complexity

When it comes to vibe coding the more number of connections you have the worse time you are going to have building that thing

You have to instruct it that it better do everything in the simplest possible form and the least number of communication links in your code

The more moving parts, the more places AI gets confused and introduces bugs.

A single source of truth beats distributed state every time.
