Hosting and cloud tools for running your own services

Estimate app resources, inspect network information, and review firewall and reverse proxy settings before deployment.

A stack of server racks with one live light: apps running yourself.

Choose a hosting check

IP and ASN lookup

Look up the RIR record for a public IP or ASN, with source-labeled BGP context when available. Registration is not geolocation or reputation.

→
A firewall shield admits only the planned NFS listener paths.

NFS firewall planner

Plan source-scoped NFSv3 or NFSv4 host-firewall listeners for firewalld, UFW, or nftables. Verified helper ports are required for NFSv3.

→
A request path changes direction on its way to the upstream.

NGINX proxy_pass calculator

Calculate the final upstream URL for one NGINX location, request target, and static proxy_pass URL. See the replacement trace and slash difference.

→

Self-hosted app resource planner

Plan RAM and storage for a self-hosted app mix with reviewed ranges, headroom, custom rows, and explicit unknowns. No runtime guarantee.

→
A checked grid stands for choosing a layout that fits the drives and workload.

Storage layout advisor

Compare layouts against your drives, failure target, and workload preference.

→

Docker Compose checker

Check one pasted Compose file for YAML, Compose structure, and static clues.
