Everything runs in your browser.
We got tired of ads, logins and paywalls for tools that should just work. So we built them ourselves. Free, fast, no nonsense — from Stockholm.
Every tool runs entirely in your browser using JavaScript. Nothing you type or paste is sent to a server. No accounts, no tracking, no logs.
No analytics, no advertising, no third-party scripts. No cookies are set. The only external request any tool makes is the IP lookup — that one has to hit a server, because your browser can't know its own public IP. Everything else is local.
Some tools save your last input so it's still there when you come back. Stored only on your device, never sent anywhere. Clear it any time from your browser settings.
Tools that save state: JSON, YAML, XML, JWT, Regex, URL Encoder, Test String Generator.
