Why I built Toololis
I got tired of the same pattern: free tool sites that demand a signup, upload your files to unknown servers, plaster the screen with ads, and then upsell a "Pro" tier. The math doesn't add up — these tools cost almost nothing to run client-side. The friction is artificial.
So I built Toololis to prove the alternative: 597+ tools, all free, all browser-only, all the time. No account. No upload. No upsell. Just utility.
What makes Toololis different
- 100% client-side — your files never leave your device. Technically impossible to leak.
- Honest analysis — supplement evidence-grading, NMN reality-check, fish-oil quality ratings. We tell users when something doesn't work, even if affiliates would pay us not to.
- Decision composites — "Should I quit my job?" tools that combine financials, life-stage, market data into a single score. No competitor combines these.
- DACH depth — 47 German tools (Bußgeld, Elterngeld, Pflegegrad, Wohngeld, Einkommensteuer 2026) where Calculator-Sites are bias-laden Versicherer-lead-gen.
- Live browser-API tools — heart-rate via phone camera, hearing-age via WebAudio, VO2max via accelerometer. Browser-tools that actually measure things.
Background
Full-stack developer based in Germany. Solo-built Toololis from zero to 597+ tools across 18 release waves. Stack: Astro 4 + Cloudflare Pages + Tailwind. Privacy-first by design — no analytics on tool inputs, no server-side processing.
What I'm working on next
- Sector deep-dives over breadth — focused tool clusters with composite scoring
- Result-sharing mechanics — your scores become OG-images you can post
- More E-E-A-T-grade content with named author bylines
- Browser-extension MVP — top tools as a sidekick
