About Mello

Mello is a growing collection of free, no-signup online utilities. Every tool runs entirely in your browser — no servers, no uploads, no tracking of your inputs.

Why browser-only?

Sending data to a server adds latency, cost, and risk. By keeping everything client-side, we can offer fast tools that handle sensitive inputs (API responses, secrets, documents) without storing them anywhere.

How is this funded?

Display advertising. We choose ad placements that don't interrupt the tools themselves.
