Hey Product Hunt community! 👋
I'm a solo developer from Turkey, and I built HızlıTools because I was frustrated with online tools that:
- Require registration for basic features
- Upload your files to their servers (privacy concerns!)
- Are slow and bloated with ads
- Charge for simple calculations
So I decided to build something different:
✅ **100% Free** - No premium plans, no hidden fees
✅ **Privacy-First** - Everything runs in your browser, files never leave your device
✅ **No Registration** - Use instantly, no email required
✅ **Fast** - PageSpeed 94/100 on mobile
✅ **40+ Tools** - PDF, images, finance, health, developer utilities
**Tech Stack:**
- Backend: ASP.NET Core 10
- Frontend: Vanilla JavaScript (no frameworks)
- Email: MailKit
- Hosting: Windows Server
**The Challenge:**
Building 40+ tools as a solo dev took 3 months of nights and weekends. The hardest part was optimizing performance while keeping everything client-side.
**What's Next:**
- Add more tools based on user requests
- Improve SEO and reach more people
- Eventually add ads to cover hosting costs (but keep it free!)
**I'd love your feedback on:**
1. Performance & UX
2. Missing tools you'd like to see
3. SEO suggestions
4. Any bugs or issues
Thanks for checking it out!
P.S. This is my first Product Hunt launch, so any advice is welcome! 😊
