Question for indie hackers and small SaaS teams

How do you currently handle website issues after deploying a change?

I'm exploring Foldnine SiteOps, a tool designed to make website operations and maintenance easier for small teams without adding another layer of complexity.

Before building further, I'd love to understand how people actually handle this today.

Do you rely on monitoring tools, manual checks, scripts, or a combination of everything?

And what's the most frustrating part of that process?

Genuinely interested in your experience — especially if you're running a small SaaS or managing multiple client websites.
