NetPulse: one command lets an AI agent health-check multiple VPS hosts

On October 3, 2026, a developer posted on V2EX to introduce NetPulse, a single-file Python tool released under the MIT license. According to the author, the motivation was practical: with several VPS instances on hand, every renewal or IP change meant checking again whether the IP was clean, whether it was native, whether DNS was leaking, whether streaming services were unlocked, and how latency and speed looked. Existing scripts, the author said, still left the output to be read line by line.

NetPulse is run locally with a single command: python3 netpulse.py --host root@vps-a --host root@vps-b --json. It performs checks on remote machines over SSH, pulls the results back to the local machine, and automatically builds a comparison table across multiple hosts. With the --json flag it returns structured output that can be handed directly to Claude or Codex to produce a Chinese summary. The author also placed a prompt on the project's homepage that users can copy and paste.

The checks cover IP cleanliness, meaning whether an address carries data-center or proxy flags; native IP status, determined by comparing the registration location from Team Cymru ASN against the IP's actual location; DNS leaks; 11 streaming-unlock checks; and reachability of the ChatGPT / Claude / Gemini APIs. At the time of this report, the material does not mention any later updates or independent verification from other sources.
