Utulio
50 free client-side tools — no signup, no data collection
50 free browser-based tools for finance, developers, students and productivity. Everything runs client-side — no backend, no accounts, nothing sent to any server. Includes: loan calculators, debt payoff planner, JSON formatter, regex tester, JWT decoder, QR code generator, invoice PDF generator, and 43 more. Built with Next.js. Lighthouse 95+ across all pages. No ads until AdSense approval — currently completely clean. Feedback on missing tools very welcome.
Hey PH community! 👋
I built Utulio after getting frustrated with tool sites
that require signups, show aggressive ads, or send your
data to servers.
The core idea: everything runs in your browser. When you
use the invoice generator, your business data never leaves
your device. When you use the password generator, your
password is never transmitted anywhere.
50 tools across 6 categories:
💰 Finance — loan, mortgage, debt payoff, compound interest
👨💻 Developer — JSON formatter, regex tester, JWT decoder, hash generator
📊 Business — invoice, receipt, quote, purchase order generators
🎓 Student — GPA, citation, grade calculator, pomodoro
🔧 Utility — QR code, unit converter, BMI, time zone
💼 Freelancer — rate calculator, word counter
Built with Next.js, 95+ Lighthouse score on all pages.
Happy to answer any questions about the build or add
tools the community suggests!
