The billet never leaves
Every tool is JavaScript running on your own anvil. Nothing is uploaded, logged or seen by us, because there is no server that could receive it.
Scale shatters, nothing is wasted
No ads, no interstitials, no account wall. What comes off the bar is the part you did not need — never your attention.
Struck cold or white-hot
Parsing and diffing move to a worker thread, so a multi-megabyte document is worked without the page ever seizing under the hammer.
Unplug the network. It still works.
