I launched a free GDPR‑compliant toolkit for European users in 48 hours — here's the full technical breakdown

Description and use

The author launched a GDPR‑compliant, browser‑only toolkit for European users in 48 hours, deploying 272 static pages with Next.js 14 on Cloudflare Workers, integrating Cookiebot CMP, and achieving 104 referring domains within three days.

Problem

Major online tools upload user files to servers, violating GDPR for European users who need client‑side processing of confidential PDFs and images.

Outcome

Within 48 hours the author launched OmniWebTool with 272 static pages, 4 languages, client‑side processing, GDPR compliance, and initial SEO traction (104 referring domains).

Workflow

• 1. Chose Next.js 14 with App Router and SSG for 272 static pages.
• 2. Added TypeScript strict mode, Tailwind CSS, and next‑intl for 4 languages.
• 3. Deployed to Cloudflare Workers via OpenNext adapter (build: npx opennextjs-cloudflare build, deploy: npx wrangler deploy).
• 4. Configured middleware to run on edge by removing explicit 'edge' runtime and using 'experimental-edge' for page components.
• 5. Implemented localized URL slugs and hreflang tags for SEO.
• 6. Added JSON‑LD schema (WebApplication, FAQ, HowTo) on every page.
• 7. Integrated Cookiebot CMP (IAB TCF v2.2) to block GA4 and AdSense until consent.
• 8. Submitted sitemap to GSC and Bing, verified, and listed on AlternativeTo and SaaSHub.
• 9. Monitored results: 272 pages indexed, 104 referring domains, 3‑day launch.
• 10. Planned expansion to 200+ tools and 300K monthly visitors.
