I’ve been building ToolsFusion quietly for the past few months alongside my day job as a Laravel developer. Today I finally launched it properly on Product Hunt, and I wanted to share it with the Dev.to community because honestly, this is the crowd I built it for.
What is ToolsFusion?
ToolsFusion is a free collection of 16 tools for developers, freelancers, and small business owners. Things like:
- AI Token Cost Calculator – paste your prompt, get the exact cost across GPT-4, Claude, Gemini
- Invoice PDF Generator – fill in your details, download a clean PDF. No account.
- Stripe & PayPal Fee Calculator – know exactly what you’ll receive before sending an invoice
- Image Compressor – drag, compress, download. Nothing leaves your browser.
- OG Meta Tag Previewer – see how your links look on Twitter, Facebook, LinkedIn before publishing
- QR Code Generator
- Barcode Generator
- Freelance Hourly Rate Calculator
- And 8 more
The thing I’m most proud of
Every single tool runs 100% in the browser.
The Invoice PDF is generated on your device. The Image Compressor never uploads your file. The AI Token Counter tokenizes your prompt locally. No data ever touches a server.
This isn’t a privacy policy promise – it’s how the code is written. I wanted to build tools I’d actually trust myself.
The tech behind it
The site is built with Laravel and Blade on the backend, but the tools themselves are pure JavaScript – no frameworks, no dependencies where possible. Browser APIs do the heavy lifting: the File API for image compression, jsPDF for invoice generation, the canvas element for QR codes.
The goal was always: fast, lightweight, zero friction.
Why I built this
I kept switching between random websites full of ads and paywalls just to calculate a Stripe fee or preview an OG tag. Every tool existed somewhere, but scattered, slow, and either behind a login or drowning in popups.
So I built the version I wanted to exist.
What’s next
I’m planning to keep adding tools based on what the community actually needs. If there’s something you find yourself Googling repeatedly or using a janky online tool for – I’d genuinely love to know in the comments.
Support the launch
If you find any of the tools useful, I’d really appreciate your support on Product Hunt today – it’s launch day and every upvote counts 🙏
