I’m looking for a NetBox or Auvik alternative — is Palpabl one

It depends on what you’re replacing. If you’re tired of self-hosting NetBox, Palpabl is a direct managed alternative built on the same model. If you’re evaluating Auvik, it’s a partial overlap — Palpabl gives you the source-of-truth and documentation layer Auvik lacks, but it isn’t a live monitoring replacement, so you’d keep a monitoring tool for that. The honest version: Palpabl replaces the documentation/source-of-truth job, not the monitoring job.
