The 9x price spread on H100 is real but the comparison requires some care. The $1.38/hr end is typically reserved or committed capacity. The $12.29/hr end is on demand at major cloud providers with full flexibility premium built in.

The more meaningful comparison is 3-year TCO for a team running consistent utilization. At 85% utilization on 1,000 GPUs, dedicated colocated infrastructure in a secondary market typically runs 40-60% of equivalent cloud cost after accounting for all non-compute costs. That range depends on your internal ops overhead and financing cost.

The silicon itself is 20-25% of total cost at scale. The rest is infrastructure, power, networking, ops, and overhead. That's why facility location matters more than people expect.

Quick context: I’ve been messing around with various coding tools and agents (GitHub Copilot, Lovable, Claude Code, Codex, etc.) for about 2 years. Before that I did zero development. I barely knew what GitHub was. I knew a bit of python and SQL but mostly spent my time in excel doing data analysis, sentiment analysis, and NLP. I never really thought of myself as a developer, and I’m not sure shipping this counts either. It’s the first open-source thing I’ve made, and I think might be useful to a few people so wanted to share it on here.

I started using Ghostty recently and kept editing ~/.config/ghostty/config, reloading, squinting, editing again every time I wanted to try a theme. Built this over a weekend so you can preview 16 palettes and 4 fonts with a background-tint slider, then copy the config lines.

One static HTML file. No build step, no tracking.
