As answered by people managing Katalon and Ezziwebtools.
Ezziwebtools's answer:
Our primary audience consists of software developers, data analysts, freelance creators, and IT professionals. Basically, anyone who needs quick, reliable digital utilities to speed up their daily workflow without having to navigate clunky interfaces.
Ezziwebtools's answer:
It started as a personal project to scratch my own itch. As a developer, I found myself constantly wasting time searching for the same utilities across dozens of different. I wanted a clean, centralized hub that just worked instantly. I built it for my own daily workflow, and it turned out so well that I decided to open it up to the community for free.
Ezziwebtools's answer:
The platform is a modern web application built primarily with Next.js, React, and TypeScript. For styling, it uses a custom, lightweight CSS system. The backend relies on PostgreSQL with Drizzle ORM and Better-Auth for user management. The AI capabilities are powered by fast LLM APIs like Groq and Llama 3.

Ezziwebtools's answer:
It bridges the gap between basic web utilities and advanced AI tools. While most sites either offer simple formatters or charge for AI features, Ezziwebtools combines standard developer utilities (like cron generators and regex testers) with powerful AI-driven tools (like SQL optimizers and API comparators) in a single, lightning-fast, brutalist-inspired interface.
Ezziwebtools's answer:
The biggest advantage is the lack of friction. Most competitor utility sites are incredibly slow, cluttered with intrusive ads, or lock their best features behind paywalls. Ezziwebtools is completely free, and fast. Even our premium AI tools are available for free with generous daily limits, allowing developers to get their work done without pulling out a credit card.
