Server checkup

Leader is the only server checkup that reads your VPS's real output and explains what to fix first.

For the solo developer or indie founder who is the only technical person in the company, running a SaaS, a side project or client sites on one to three Linux VPS.

Hand-drawn diagram: your VPS gives output, and the output turns into findings labelled fix first, next and later.

One script. Read it first.

Sample

Invented output, shown only to illustrate the shape of a Free Checkup.

What your VPS printed

  • sshPasswordAuthentication yes
  • sshPermitRootLogin no
  • net5432/tcp listening on 0.0.0.0
  • disk/ is 61% used
  • updatesunattended-upgrades not installed

Findings, most urgent first

  • High

    SSH accepts password logins.

    Confirm your key login works in a second terminal first. Then:

    sudo sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config && sudo systemctl reload ssh
  • Medium

    Postgres listens on every address, port 5432.

    Set listen_addresses = 'localhost' in postgresql.conf. Then:

    sudo systemctl restart postgresql
  • Low

    Automatic updates are not installed.

    On Debian or Ubuntu:

    sudo apt install unattended-upgrades

Who Leader
is for

A solo developer or indie founder, often the only technical person in the company. You run a SaaS, a side project or client sites on one to three Linux VPS. You are comfortable with a terminal and SSH, and you are not a sysadmin.

What you run
on your server

One read-only, open-source script. You can read it before you run it. Every finding comes from what your own server printed, so nothing is guessed.

How it
works

  1. Read the script. It is short, read-only and open source. Open it and see what it does before it touches anything.
  2. Run it on your VPS. It prints what your server really says about itself.
  3. Paste the output. You get a summary of findings by severity, with the exact commands to fix the first ones.
