Vibe coding breaks when you build real SaaS

Vibe coding works fine for tiny stuff.

But once you try to build an actual SaaS, the problems show up fast.

What I kept running into

  • prompts were too vague
  • context got messy
  • edge cases were easy to miss
  • small changes started breaking other parts
  • the code looked fine at first but needed a lot of cleanup later

What started working better

  • write a spec first
  • break the work into small pieces
  • keep the context short
  • review before moving on

I tried a few tools for this like Cursor Claude Code Google Antigravity and Windsurf

The pattern I keep seeing is that the model matters, but the workflow matters more.

That is also why something like Traycer felt useful to me.

It feels more focused on planning and structure first instead of just jumping straight into code.

For SaaS work, that matters a lot more than people think.

Because building a real product is not just writing features.

It is keeping scope clean, not losing track of the spec, and making sure the code still matches what you actually wanted.

My rough flow now looks like this

spec → small tickets → execution → review

It is not fancy, but it is way less chaotic than just prompting and hoping for the best.

Curious how other people are handling this when building SaaS.

Are you still mostly vibe coding, or do you use a more structured flow now?
