I am surprised no one has mentioned Heroforge yet. It's an Excel spreadsheet and doesn't get everything right, but can be a really useful tool. In it is a buffs page which automatically updates the character-sheet pages with the buffs.
Note, it has errors and cannot handle some classes properly (Mythic Exemplar for one) so always double check it's output.

They also have a lot of other tools...

Now, even if you can't use what's there as it is not web, you may find it very useful in terms of ideas.

Thanks, I'll have a look and try to get some ideas from there. I tried heroforge a few times but it never worked for me. Do you know if it's strictly SRD or does it include licensed material?
