RunToolify

A free developer toolkit for developers, designers, and creators who need quick daily utilities. It brings code execution, file conversion, and useful tools into one product without forcing users to sign up.

The developer tools space is crowded with tools scattered across dozens of different websites — each requiring a separate tab, often a separate account, and frequently interrupted by paywalls. The challenge was building a unified toolkit that felt genuinely useful rather than just another aggregator, while keeping it completely free and accessible without any login friction. Building full-stack from scratch also meant architecting a system where tools could be added and extended over time without breaking existing functionality.

I designed RunToolify as a full-stack Next.js application deployed on Vercel, with server-side logic handling the compiler execution, PDF processing, and image conversion. The UI is built for speed — a sidebar navigation with category grouping lets users find any tool in under two clicks. Dark mode is supported from day one. The architecture is modular — each tool is an independent component that can be improved or expanded without affecting others.

• Multi-language code compiler — 12+ programming languages
• PDF tools — merge, split, compress and convert
• Image converters — format conversion and optimization
• Design and color utilities for developers and designers
• Finance calculators — EMI, SIP, tax and more
• Web and asset tools for developers
• 100% free — no signup or login required
• Dark mode support

RunToolify is live and actively used by developers and designers who want a single, free, no-login toolkit. The product demonstrates my ability to take a concept from zero to a fully deployed, production-grade SaaS application — handling ideation, UI design, full-stack development, and deployment entirely independently.
