While vibe-coding does favor build over buy for some products, it won't replace mission-critical tools in the foreseeable future
Here’s my take on what gets killed, what survives, and the build-vs-buy rule that actually works:
I believe that AI does not kill SaaS. It eliminates the “thin wrapper”: software that offers little more than a polished UI for simple automations. Today, any developer can stitch these tools together in an afternoon.
Still, SaaS is not disappearing; it is evolving. While products that sell mere convenience will face extinction, products that sell reliable outcomes for high-stakes problems will thrive. This guide covers what survives the shift toward vibe-coding and how to decide whether to build or buy.
