Paramlet

View, edit and save the query parameters of the current page.

Paramlet shows the query parameters of the current page as an editable list. Click the toolbar button and you get one row per parameter, with the values decoded so they are easy to read. Edit any key or value, delete rows or add new ones, then apply the result or copy the new URL. Only the parameters you change are rewritten. The rest of the URL keeps its original encoding and repeated keys. Remove tracking takes out utm_source, utm_medium, gclid, fbclid and other known tracking parameters in one click. Useful before sharing a link. Presets are named sets of parameters, like debug=1 and log=verbose for a dev server. Save one for the current site or for every site, then apply it with a click or with the number keys 1 to 9. Presets can be reordered by dragging, and the settings page can export them to a file and import them back. It also handles parameters after the # in single-page app URLs, lets you paste a whole URL or query string to add its parameters, and shows a search box when a URL has a lot of parameters. Paramlet makes no network requests and does not collect any data.
