tip.plato-potato.comMost online developer utilities upload your data to a server to "process" it. That data lives in their logs forever, or worse — leaks when they get breached (see the 2025 JSONFormatter incident). plato·potato is a deliberate alternative: every tool runs entirely in your browser, with verifiable behavior.
Each tool is fully self-contained on its own subdomain (e.g. json.plato-potato.com). This means the JSON tool's code never loads when you're using the cron tool. Each subdomain is a single ~12 KB HTML file that loads in milliseconds. SEO ranking is also per-subdomain, so each tool can rank on its own merits for its keyword.
Only Cloudflare Web Analytics — anonymous, cookieless, just page-view counts and country. No GA4, no tracking pixels, no fingerprinting. You can verify by opening DevTools → Network and pasting your input: you'll see zero outbound requests carrying your content.
Free, no signup, no ads currently shown. Once we hit ~500 visitors/day we plan to apply for Google AdSense to keep the lights on — but ads will be unobtrusive (no popups, no autoplay videos, no interstitials). If you'd rather not see any ads, use an ad-blocker; the tools work either way.
Once the page is loaded, yes — the tool runs entirely in your browser. The single HTML file caches normally. We don't ship a service worker for explicit offline mode yet, but it's on the list.
