Health checks and live previews for every localhost

Is :3000 the docs site or the admin panel, and is it actually up? One look answers both.

In short

While the panel or window is open, Portlivo sends each web server a plain GET / and colours it by the answer: 2xx green, redirects teal, 4xx orange, 5xx red. It shows the response time and, in the window, a live thumbnail of the page. You can probe /health or any other path instead.

How it checks

  • A raw HTTP request over TCP to localhost, with a 1.5 second timeout. Only a real HTTP/1.x status line counts, so a database port is never mistaken for a website.
  • Redirects aren’t followed, so a probe never leaves your Mac.
  • Each probe is a real request in your server’s own log, so a port is probed at most every 30 seconds, and only while you’re looking.
  • Response times over a second show in orange.

A custom health path

If / is slow or needs a login, set the path in the inspector’s health section: /health, /up (Laravel 11) or anything starting with a slash. It’s remembered per port.

Live previews

Each server that answers with a page gets a thumbnail in the window. Portlivo loads it in a hidden web view, one server at a time, at most once a minute, and only while the window is open. Error pages aren’t captured. Turn previews off in Settings → Website previews.

Questions people ask

Will the checks show up in my server’s log?
Yes, as an ordinary GET request, at most every 30 seconds per port and only while the panel or window is open. Point the check at a cheap path if that’s noisy.
Does it check HTTPS?
It sends plain HTTP to localhost. A server that only speaks HTTPS shows as not HTTP, and Portlivo doesn’t guess.
