Ethernity is a premium Astro theme for analytics platforms, SaaS products, and B2B companies that want to look like they have taste.


Not another hero with floating notification cards. Not another gradient blob background. Not violet.



The design choices that make it different:


Bloomberg terminal hero. The hero section's right side is a real data table — METRIC / VALUE / DELTA / UPDATED columns in IBM Plex Mono. Looks like an actual dashboard. Nobody else is doing this.


Inverted orange CTA. Full orange background section instead of the 47th navy-to-purple gradient. Breaks visual monotony and actually stands out in scroll.


Editorial feature rows. Three-column layout: eyebrow label | title | description. Hairline dividers. No icon grids, no badge stacks. Reads like a magazine.


CLI terminal steps. HowItWorks section shows real command-line output. Talks to the technical audience you actually want.


True neutral black. Background is #0A0A0A — no blue tint, no "dark navy" compromise that just makes everything look purple.
