TinyKit, a hundred little jobs for the browser

Field notes

The collection is organized into categories covering text, data and code, encoding, numbers, time and dates, images and colour, security, codes and IDs, and files and systems. Visible examples include a template filler that expands one template across tabular data, a Markdown previewer that provides HTML output, and a post-length checker that includes links and emoji in its count. The homepage states that processing runs in the browser rather than on a server.
