I’m sure there is a website somewhere. But yeah, there’s pretty much three kinds of radicals: ones that share their reading, ones that share their meaning, and ones that are either pictograph-based, or just modified from some other radical. Sometimes they overlap.
For example, 日 tends to share its meaning – kanji with the 日 radical (at least when it’s on the left) tend to have a meaning related to time. For example, 時, 曜 or 暇. On the other hand, 方 tends to share its reading (ほう) – such as 放, 訪 or 芳. Once you start getting a feel for which radicals do what, it’s a good way to intuit either the meaning or the reading of a kanji you’ve never seen before.
