Many utilities transmit your input to backend servers. When you're dealing with sensitive API keys, customer logs, or private tokens, that's a security and compliance nightmare.</p> <p>To fix this, I created <strong><a href="https://kitloft.dev" rel="noopener noreferrer">Kitloft</a></strong>.</p> <h3> What makes Kitloft different? </h3> <ol> <li> <strong>100% Client-Side Execution:</strong> Every single tool runs locally in your browser using modern Web APIs and local libraries. Your files and text never touch a remote server.</li> <li> <strong>Zero Friction:</strong> No sign-up walls, no accounts to manage, and no hidden subscriptions.</li> <li> <strong>Privacy-First Sharing:</strong> Shareable configurations use URL hash fragments (<code>#</code>), which browsers never transmit over the network. Sensitive parameters are stripped automatically.</li> <li> <strong>No Tracking Cookies:</strong> Analytics are strictly cookieless and privacy-respecting.</li> </ol> <h3> Give it a spin </h3> <p>Check it out at <strong><a href="https://kitloft.dev" rel="noopener noreferrer">https://kitloft.dev</a></strong>.</p> <p>I would love to get your honest thoughts:</p> <ul> <li>What tools are missing that you find yourself using every day?</li> <li>How is the UI and speed on your machine?</li> </ul> <p>Drop your feedback in the comments below!</p> webdev privacy devtools javascript
