I built a lightweight, client-side toolbox of frontend developer utilities

Hey everyone! 👋

As a frontend developer, I find myself using small utility tools every day—testing Open Graph cards, generating JSON-LD schemas, converting PX to REM, or grabbing a quick CSS bounce animation.

Instead of jumping between 5 different websites to do this, I decided to build a single, unified workspace that has all these common developer helper tools in one place: FrontendHelpers.com.

What makes it different?

Client-Side & Secure: All calculations, converters, and previews run entirely inside your browser using client-side JavaScript. Nothing you enter (meta descriptions, business details, or colors) is transmitted or stored on any server.
Zero-Signup: No accounts, no email walls, and no usage limits. Just open the page and use the tool.
Dark, Cohesive Design: I wanted a UI that felt premium and unified, using a modern dark theme and smooth micro-interactions instead of plain browser defaults.

🛠️ What's in the box?

The site currently features 12 utility tools divided into major categories, plus interactive libraries:

1. SEO & Metadata Tools

Meta Tag & Social Previewer: Type in your metadata and preview how your site will look on Google search results, Facebook, and Twitter.
JSON-LD Schema Generator: Build valid Schema markup (FAQ, Local Business, Articles) with direct validation links.
Robots.txt & Sitemap Helpers: Generate clean robots configurations.
UTM Link Builder & URL Slug Generator.

2. Design & CSS Tools

WCAG 2.1 Contrast Checker: Checks foreground/background contrast ratios against official AA/AAA accessibility standards.
PX to REM Converter: Convert measurements instantly.
Interactive CSS Gradient & Box Shadow Creators: Drag sliders to customize styles and copy copy-paste ready CSS.

3. Libraries (Animations & JS Snippets)

CSS Animation Playground: 46 ready-to-use CSS animations (fades, slides, bounces, hovers) with preview cards and clean code copy.
JS Tricks & Tips: A collection of 28 modern JavaScript snippets (debounce, deep clone, device checks) fully explained.

I'd love your feedback!

Since this is a brand new project, I want to shape it around what developers actually need.
