Why Use Browser-Based Developer Tools?
Pasting API keys, config snippets, or real data into an unfamiliar formatter site is a common source of accidental leaks. EverydayTools' developer utilities are built to run entirely client-side, so nothing you paste in is ever sent to a server.
Because formatting, generating, and encoding all happen with JavaScript in your own browser tab, these tools are safe to use with real project data, not just placeholder examples. That makes them a practical everyday toolkit alongside your usual development setup.
