I Built a Free All-in-One Tool Website with 70+ Tools — Here's the Story

Source: Dev.to

Why I Built FixFlowHub

I was constantly frustrated switching between different websites for simple tasks:

• Compress an image → TinyPNG
• Merge a PDF → SmallPDF (with watermark 😤)
• Check grammar → Grammarly (paid)
• Generate a QR code → some random sketchy site

Most tools either require sign‑up, add watermarks, or lock basic features behind a paywall.
So I decided to build one place where everything is actually free.

What I Built

Tech Stack

Key Design Decisions

• Privacy First: All image and PDF processing happens in the browser. Files are never uploaded to any server.
• No Sign‑Up: I wanted zero friction. Open the tool, use it, done.
• No Watermarks: Every tool is fully functional for free.

What I Learned

• Building is the easy part — getting traffic is hard 😅
• SEO takes time — don’t expect results overnight
• People appreciate simplicity — no popups, no forced sign‑ups, just working tools
• Free tools attract users — but monetization needs thought
