AI Analysis

●●SolidEye CandySolve My Problem

Bufferbloat grading reveals Zoom lag you'd miss on Speedtest; Bubble Tea UI delight.

Strengths
  • •Identifies real problem (loaded latency ≠ idle latency) that standard tests ignore
  • •Zero config: leverages Cloudflare infrastructure, no API keys or accounts
  • •Polished TUI with sparklines, history tracking, colorblind-safe themes, cross-platform
Weaknesses
  • •Novelty is UI polish on existing problem; bufferbloat grading not new
  • •Single-purpose tool in crowded speedtest space; depends on Cloudflare uptime
Target Audience

Network engineers, DevOps, developers debugging connection quality issues

Post Description

Hey HN, I wanted a speed test I could run from the terminal that wasn't ugly. So I built one.

It's a Go TUI (Bubble Tea) that runs against Cloudflare's speed test infrastructure. No API keys, no accounts, fun UI.

One thing I added that I've found genuinely useful: it also pings during the throughput test and compares idle vs loaded latency, which gives you a rough bufferbloat grade. Handy for figuring out why your Zoom calls lag even when speedtest.net says you're fine.

Happy to hear what you think.
