A few weeks ago I set out to build a comprehensive collection of free browser-based tools. The result: alltools.app — 562 tools
across 22 categories.
The core rule: Everything runs client-side.
No uploads. No accounts. No limits. Ever.
The stack
- Astro 6 — static site generation
- Cloudflare Pages — free hosting, edge CDN
- Tailwind CSS v4 — styling
- pdf-lib + PDF.js — PDF processing
- Canvas API — image processing
- Web Crypto API — security tools
- MediaRecorder API — video/audio tools
What surprised me
562 tools is achievable client-side.
I expected to hit walls — video compression, PDF manipulation, image processing. But browser APIs have matured enormously.
ffmpeg.wasm, pdf-lib, and the Canvas API handle more than I expected.
Static + Edge = zero infrastructure cost.
685 static pages deployed on Cloudflare Pages.
Zero server costs. Zero maintenance.
SEO at scale is a different problem.
562 tool pages means 562 opportunities for long-tail keywords. But it also means 562 pages that need quality content.
The philosophy
Most "free" online tools upload your files to remote servers. Your resume, invoices, photos, passwords — they all pass through infrastructure you don't control.
We built an architecture where that's impossible. Files never leave your browser.
What's next
- Chrome Extension (built, submitting to Store)
- Arabic translation (MENA)
- 8 new high-value tools.
Happy to answer questions about the architecture, the Astro setup, or client-side processing at this scale.
