Acquisition breakdowns, engineer reviews & open-source metrics- Post excerpt:
- With a friend from the university, we realized that many developers are pasting sensitive data on random websites in order to decode some Base64, JWT, compress some images...etc without wondering what the website does with this data. Therefore, we developed a free, open source and completely offline Windows app designed to help with these little common tasks
- What engineers like:
- Windows app providing lots of useful common tools in a single (offline) app. Includes convertors e.g. JSON to YAML; encode/decode e.g. URL, base64; generators e.g. hashes, lorem ipsum; graphics e.g. format convertor. Supports compact mode and pinning to the start menu. Open source.
- Trade-offs & limitations:
- Windows only.
- Best suited for:
- Developers on Windows should consider this tool for common development tasks

# Design Brief: Gradient Glow (with Dark Developer)
Luminous radial glows and translucent glass panels, widely used across modern AI products.
## Design Tokens
```css
:root {
--background: #682a87;
--surface: #292929;
--foreground: #f4f0f7;
--muted-foreground: #c8b9d2;
--accent: #9846d0;
--radius: 8px;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #682A87 (~76%) · Surface #292929 (~13%) · Text #F4F0F7 (~6%) · Muted Text #C8B9D2 (~3%) · Accent #9846D0 (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Centered Headline + CTA
- 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: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot
- Spatial layout notes: Centered Headline + CTA hero structure paired with download app / install extension CTA and live generated output showcase.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring centered headline + cta layout and product ui screenshot / component visuals.
## Avoid
- Muddy low-contrast text over gradients
- Overuse of full-screen rainbow backgrounds
- Cluttered dense tables in the hero
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.
