Built 14+ Free Online Tools in Just One Week – Meet ToolEka

A week ago, I challenged myself to build a collection of free online tools from scratch.

Today, I'm excited to share the first version of ToolEka 🎉

👉 https://tooleka.com

The idea wasn't to create another generic calculator website. I wanted to build a platform that is fast, simple, mobile-friendly, and actually useful.

🛠️ Tech Stack

  • Next.js
  • React
  • Tailwind CSS
  • TypeScript
  • Cloudflare Workers
  • Cloudflare R2

I chose Cloudflare Workers because I wanted global performance with minimal infrastructure management.

✨ What's Available Right Now?

The first release includes 14+ free tools, including:

  • Health calculators
  • Finance calculators
  • Developer utilities
  • Text tools

Every tool is designed to work instantly without requiring an account.

💡 Why I Built It

While searching for online tools, I noticed that many websites are:

  • Slow to load
  • Filled with intrusive ads
  • Not optimized for mobile devices
  • Cluttered with unnecessary features

I wanted to build something that focused on speed, simplicity, and usability.

🚧 Challenges Along the Way

Building the project in one week wasn't easy.

Some of the biggest challenges included:

  • Deploying Next.js on Cloudflare Workers
  • Optimizing performance and Core Web Vitals
  • Adding SEO metadata and structured data
  • Making every page responsive
  • Building reusable components for future tools

Each challenge helped me learn something new.

🚀 What's Next?

This is only the beginning.

My roadmap includes:

  • 100+ free online tools
  • AI-powered utilities
  • More developer tools
  • Better accessibility
  • Continuous UI and performance improvements

🙌 I'd Love Your Feedback

If you're a developer, designer, or someone who frequently uses online tools, I'd really appreciate your feedback.

Some questions I'd love to hear your thoughts on:

  • Is the UI intuitive?
  • Which tools should I add next?
  • Did you notice any bugs or performance issues?
  • What would make you come back and use it again?

I'm building this in public, so every suggestion is valuable.

Thanks for reading! ❤️
