Hosting and cloud tools for running your own services
Plan and check a self-hosted server: whether your apps fit its RAM and disk, which ports NFS needs open, what URL nginx passes to your app, and who an IP address is registered to. Have the values from your server or config ready.
Tools

See who an IP address or AS number is registered to, and its abuse contact.

Get the ports and firewall rules NFSv3 or NFSv4 needs on a server or client.

See the upstream URL nginx sends for a location and proxy_pass, with and without the slash.
Self-hosted app resource planner
Check whether a set of self-hosted apps fits your server's RAM and disk.
Storage layout advisor
Compare RAID and ZFS layouts for your drives and failure target.
Docker Compose checker
Find YAML errors, broken references, and open ports in a pasted Compose file.
