Redline, by Coder B

About this demo

What you're actually looking at

Redline, by Coder B, is a small, self-hosted site engine written in Rust — a single Axum binary that serves plain HTML pages through a lightweight templating layer and automates the SEO/GEO plumbing (sitemap, robots.txt, llms.txt, OpenGraph, JSON-LD, security headers) most site builders either bolt on or skip. No CMS, no build pipeline, no npm install.

Two claims, both checkable

This site isn't trying to sell you anything — that's what coderb.dev/redline is for. It exists to demonstrate, with a page you can inspect yourself, two things:

Vanilla HTML/CSS/JS holds up

Every interactive piece on the home page — the gauge, the live stats, the filterable grid, the step-through — is plain DOM APIs. No framework, no bundler, view-source is the actual source.

Redline automates the plumbing

The generated files linked from the home page's "What Redline generates automatically" section aren't hand-written — they're rebuilt from page metadata at every startup.
