How do the categories on the left work?

Each one filters the list beside it without leaving the page, and the number next to a category is how many tools are in it. A category shows up to 50 tools; if it holds more, a “See all” link under the last card opens that category’s own page, where the full set is listed.

How is this list ordered?

Alphabetically by tool name, because the names describe what the tools do — “avif to png”, “json formatter”, “bmi calculator” — so a visitor who knows the job can find it by name. The sort menu can reverse it, or switch to recently added and recently updated to see what has changed.

How does the search work?

It matches tool names and descriptions, so a job you can only half-name will usually surface. Search combines with the selected category and the sort order, and every combination has its own URL, so a narrowed view can be bookmarked or shared.
