I spent the last week building HeadlineBoost - a suite of 60+ completely free SEO and developer tools.
No signup walls. No credit cards. Just tools that work.

Why I Built This
I was tired of:
- Paying $50/month for simple tools
- Signup walls for basic features
- Tools that don't actually work
- "Free" trials that require credit cards
So I built my own suite.
Tech Stack
Framework: Next.js 15 with App Router
Language: TypeScript
UI: Tailwind CSS + shadcn/ui
Runtime: Node.js (for DNS, SSL, WHOIS)
Deployment: Vercel (Edge runtime)
AI: OpenAI GPT-4o-mini
What I Learned
SEO content matters: Added 2500+ words per tool page
Real data wins: Users prefer actual DNS queries over simulated data
No signup = more users: Removing barriers increased usage
Educational content ranks: Google loves comprehensive guides
