Hosting and cloud tools for running your own services
Estimate app resources, inspect network information, and review firewall and reverse proxy settings before deployment.
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.
NFS firewall planner
Plan source-scoped NFSv3 or NFSv4 host-firewall listeners for firewalld, UFW, or nftables. Verified helper ports are required for NFSv3.
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.
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.
