I Built a Hub of 20+ Free Developer & Finance Tools (All-in-One Utility Hub)

Hey Dev Community! πŸ‘‹

As a developer, I often found myself jumping between twenty different tabs just to format a JSON string, calculate AdMob revenue, or check a password's strength. I decided to fix that by building a centralized, high-performance home for these utilities.

I’m excited to share SRF DEVELOPER Tools β€” a modern, mobile-responsive utility hub built specifically for developers, students, and digital creators.

What’s inside? πŸ› οΈ

I’ve categorized 20+ tools into three main sections to keep your workflow smooth:

  • Developer Essentials: JSON to Dart Converter (perfect for Flutter!), SQL Formatter, HTML/CSS Minifier, and Base64 Encoder/Decoder.
  • Finance & SaaS: AdMob Revenue Predictor, Cloud Hosting Estimator (AWS/Azure/GCP), and a Global Discount Calculator with automatic currency detection.
  • SEO & Marketing: Meta Tag Generator, YouTube Thumbnail Previewer, and Reading Time Calculator.

Why I built this? πŸ’‘

As a BCA student specializing in Software and App Development, I wanted to create something that wasn't just another tutorial project. I focused on building a "one-time" resource that provides real value to the community.

Key focuses during development included:

  • Speed: Clean code architecture with a performance-first approach.
  • SEO: Optimized for search engines with a perfect 100 SEO score.
  • UX: A dark-mode first, SaaS-style aesthetic that looks great on desktop and mobile.

The Tech Stack πŸ’»

  • Frontend: React with Tailwind CSS for modern, sleek styling.
  • Logic: Native JavaScript Internationalization (Intl) API for location-aware currency detection.
  • Optimization: Implemented lazy loading to ensure fast initial paint times.

The site is 100% free, and I'm constantly adding new tools based on feedback. If you are a Flutter developer or a web dev looking to save a few minutes every day, give it a look:
