As answered by people managing 99Tools.net and StackBlitz.
99Tools.net's answer
What sets 99Tools apart is the sheer scale and variety of our library. While most utility sites focus on a narrow niche, we provide a unified "mega-hub" of over 800+ free tools covering text, code, web, and data. We combine this massive variety with a "Privacy First" architecture, ensuring that our utilities are not just fast, but 100% secure for professional use.
99Tools.net's answer
Users choose 99Tools because we eliminate "tab fatigue." Instead of bookmarking twenty different sites for JSON formatting, SEO checks, and image compression, you can find everything in one lightning-fast interface. Unlike many competitors, we are committed to being 100% free without intrusive ads, forced registrations, or "freemium" limitations that slow down your workflow.
99Tools.net's answer
Our primary audience consists of digital power users who value efficiency. This includes:
Developers & Engineers looking for quick code formatting and debugging tools. Content Creators & SEOs needing text manipulation and web optimization utilities. Students & Researchers who require fast data conversion and calculation tools. IT Professionals seeking secure, browser-based utilities that don't require software installation.
99Tools.net's answer
99Tools was born out of a simple frustration: the modern web is filled with "single-purpose" tool sites that are often slow, cluttered with ads, or insecure. We wanted to build the ultimate digital Swiss Army knife a clean, centralized, and high-performance portal where anyone could access professional-grade utilities instantly. Our mission has always been to democratize access to productivity tools while keeping the user's data privacy at the forefront.
99Tools.net's answer
99Tools is built using a modern, high-performance web stack centered on JavaScript (ES6+) and React to ensure a responsive, "app-like" experience. To uphold our security promise, many of our tools utilize Client-Side Processing. This means your data is processed directly in your browser and is never sent to our servers, providing an extra layer of privacy for sensitive code and text.

I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
