Free browser-based developer tools and student calculators for Pakistani universities.
This page is designed to help you find out whether DevToolsKit.tech is good and if it is the right choice for you.
DevToolsKit Hub is a free collection of browser-based tools in two groups. For developers: a JSON formatter and validator, a regex tester with live matching, a Base64 encoder/decoder, a JWT decoder, and a UUID generator — each paired with a plain-language guide. For students in Pakistan: university-specific GPA and CGPA calculators (Punjab University, COMSATS) built on each university's official grading scale, merit/aggregate calculators, and published closing-merit data for Punjab University admissions. All tools are free, need no account, and process input locally in the browser — data is never uploaded to a server.

Next.js, React, TypeScript, Tailwind CSS, deployed on Vercel.
It combines everyday developer utilities with university-specific Pakistani student calculators in one free, no-sign-up site. Everything runs locally in the browser, and the student calculators are built from official grading scales, prospectus formulas and published closing-merit data rather than generic formulas.
It is free, needs no account, and never uploads the text or marks you enter — the tools work entirely in your browser. For students, it goes beyond a generic calculator: each university page uses that university's own formula or grading scale, and the merit calculators include target finders that work backwards from the score you need.
Two audiences: developers and programming students who need quick utilities (JSON, regex, Base64, JWT, UUID), and students in Pakistan who are applying to universities or tracking their GPA/CGPA — especially applicants to Punjab University, COMSATS, UET, FAST-NUCES and medical colleges via MDCAT.
DevToolsKit Hub started as a small set of browser-based developer utilities and grew after seeing how hard it is for Pakistani students to find reliable GPA and admission aggregate calculations in one place. Many calculators online use generic or outdated formulas, so the student section was built around official university grading scales, prospectus formulas and published closing-merit data, explained in plain language.
None — DevToolsKit Hub is free and has no paying customers; it is used by individual developers and students.
