Free VPS & DNS Toolkit for Developers and Server Admins
Practical tools, checklists, and guides for testing VPS performance, fixing DNS issues, and running Linux servers in production. No signups. No fluff. Just commands that work.
Tools and guides
VPS Benchmark Checklist
Test CPU, RAM, disk I/O, network throughput, and latency on any Linux VPS before you commit to a provider. Copy-paste commands included.
DNS Propagation Troubleshooter
Step-by-step diagnosis for "my DNS isn't updating", "domain not resolving", and stuck propagation. Works for any registrar or DNS host.
Who this is for
- Developers who buy a VPS and want to verify they actually got what they paid for.
- Sysadmins debugging DNS, latency, or routing problems on production servers.
- Hosting customers comparing providers, locations, and plans before purchase.
- Self-hosters running Docker apps, VPNs, game servers, or control panels.
The approach
Every page on this site is built around one principle: a person searched for a real problem, and this page should solve it in one read. That means short pages, exact commands, and no marketing detours. If a guide here doesn't help you finish the task, it shouldn't exist.
