The Problem
Every time I needed to decode a JWT or generate a bcrypt hash,
I had to use ad-heavy websites that might be logging my input.
I couldn't find a single clean, trustworthy, all-in-one toolkit.
So I built one.
What I Built
Bizmatepro (https://www.bizmatepro.xyz/) is a free,
privacy-first toolkit with 100+ utilities for developers,
marketers, and security professionals.
The Core Rule
Everything runs client-side. No exceptions for sensitive tools.
Open DevTools → Network tab while using the JWT decoder
or password generator. Zero outbound requests.
Tech Stack
- Plain HTML/CSS/JS (no heavy frameworks)
- Cloudflare for edge caching and security
- Render for hosting
- Google APIs for DNS/IP lookups
- No database whatsoever
What's Inside
Security tools
- Password generator (offline)
- JWT decoder (offline)
- Bcrypt/HMAC/hash generators
- CC validator (Luhn algorithm)
Developer utilities
- JSON/XML formatter and validator
- Regex tester
- SQL formatter
- Base64, URL encoder, hex tools
Network & SEO
- DNS lookup
- SSL checker
- Meta tag analyzer
- SERP simulator
Business tools
- Invoice generator → PDF
- Quote builder → PDF
- Receipt maker → PDF
100+ tools total across 10 categories.
Business Model
No ads. No VC money. Donations only.
Controversial? Maybe. But I wanted to prove that
a useful product doesn't need to monetize its users.
2 Weeks In — Honest Numbers
- 56 total users
- 1.7K events
- Traffic from: USA, Indonesia, Germany, Bangladesh, UK
- Donations: $0 so far 😅
What I Learned
- Building is the easy part. Distribution is everything.
- "Privacy-first" is a feature, not just a tagline.
- The developer community is incredibly skeptical (rightfully so) about client-side claims.
- Reddit and HN are brutal but honest.
What's Next
- Open sourcing the codebase
- Adding more AI-powered tools
- Building a proper API for developers
