+# Unduck
+
+DuckDuckGo's bang redirects are too slow. Add the following URL as a custom search engine to your browser. Enables all of DuckDuckGo's bangs to work, but much faster.
+
+```
+https://unduck.link?q=%s
+```
+
+## How is it that much faster?
+
+DuckDuckGo does their redirects server side. Their DNS is...not always great. Result is that it often takes ages.
+
+I solved this by doing all of the work client side. Once you've went to https://unduck.link once, the JS is all cache'd and will never need to be downloaded again. Your device does the redirects, not me.
