Django Toolbox
I put the small web utilities in one place. They were starting to need a directory.
I maintain Django Toolbox, the utility site at tool.brighteng.org. A shared registry gives each tool a place in the catalog, with English and Chinese descriptions.
One toolbox, many small jobs
Django handles the routes and templates. Shared static assets and structured tool metadata keep the individual utilities consistent. I can add a tool without rebuilding the navigation by hand.
The source is public, including the registry and translation data.
