Why these run in the browser

Most online utilities post whatever you paste to a server and do the work there. That is fine for a toy input and a bad habit for anything else — API responses carry customer names, tokens carry credentials, and a log line carries both. Every tool in this section works with the browser's own APIs, in the tab you already have open. The practical upside is speed: no upload, no queue, no round trip, and the page keeps working with the network off. The trade-off is size — a browser tab will not chew through a 500 MB dump, so we cap the input rather than let the page freeze.

What is coming next
