What is Utilix?
Utilix is a free, browser-based utility website for developers, Nepali professionals, and general users. Every tool in the site processes your data locally in your browser using JavaScript — no server ever sees your files, tokens, or financial data.
The developer section is built by a fintech engineer with deep context in payment systems, banking APIs, and ISO 8583. Tools like the ISO 8583 message parser, HMAC generator with Fonepay/NCHL presets, and JWT decoder reflect real-world integration work — not textbook examples.
The Nepal finance section fills a gap that global tools cannot: current IRD income tax slabs updated each fiscal year, Bikram Sambat calendar conversion with accurate month-length tables from 2000 BS to 2090 BS, and an IPO allotment calculator that understands NEPSE's lottery rules and explains the common misconception about kitta quantities.
Privacy is the core differentiator. When you use Utilix to format JSON with API keys in it, merge confidential PDFs, or calculate your salary, none of that data is transmitted anywhere.
