As answered by people managing Dofollow.Tools and Cert Decoder.
Dofollow.Tools's answer
Dofollow.Tools was born from recognizing a gap in the rapidly growing AI tools market. As AI solutions exploded in popularity, creators struggled to reach their target audience while users faced information overload when discovering tools. Created by @judewei_dev, a developer who understood both sides of this challenge, we built a platform that solves discovery problems while providing genuine SEO value through dofollow backlinks—creating a win-win ecosystem for the entire AI community.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Dofollow.Tools's answer
Dofollow.Tools is built on a modern, scalable tech stack: Frontend: Next.js 15 with React 19 and TypeScript for type-safe development, UI: Radix UI components with Tailwind CSS for responsive design, Backend: Supabase (PostgreSQL) for data management, Payments: Stripe integration for seamless subscriptions, AI Integration: Multiple providers including OpenAI, Anthropic, and Replicate, Deployment: Optimized for Vercel with excellent performance and SEO.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
