Before your first 100 customers, monitoring can feel like something you will set up later.

You are still building features. You are still finding positioning. You may not have paid users yet. A full observability stack sounds like overkill.

That instinct is partly right. An indie SaaS founder does not need a complex enterprise monitoring setup on day one.

But you do need to know when the few things that matter most are broken.

Early users are fragile. They do not have a long history with your product. If your homepage is down, signup fails, SSL expires, or your first onboarding email never triggers, most people will not open a support ticket. They will simply leave.
