Post excerpt:
Hi HN — solo developer here. I built this tool ~4 years ago purely to solve my own frustration with CORS and repeated proxy setup. The idea was intentionally boring: just prefix a URL and get control over the request and response. Somehow it grew to serving billions of requests per day, including usage by companies and universities. I’m sharing it here mainl

# Design Brief: Dark Developer (with Precision Swiss Grid)

Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.

## Design Tokens

```css
:root {
  --background: #050505;
  --surface: #171717;
  --foreground: #ffffff;
  --muted-foreground: #a3a3a3;
  --accent: #ffffff;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #050505 (~62%) · Surface #171717 (~16%) · Text #FFFFFF (~10%) · Muted Text #A3A3A3 (~8%) · Accent #FFFFFF (~4%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Code Block / Terminal / CLI
- Conversion CTA: Start Free / Sign Up · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Outcome & Speed Promise
- Hero components: Code & Terminal
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and stacked avatars & testimonials.
- Visual summary: Dark Developer (Dark canvas, balanced density) featuring split copy & visual layout and code block / terminal / cli visuals.

## Avoid

- Warm pastel backgrounds
- Playful cartoon illustrations
- Oversized pill buttons everywhere

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
