no javascript xp tracker / differ for lost city. no affiliation with that nor with runescape. how 2 use: travel to /{rsn} or search down below, click on new snapshot to create your first snapshot.you can click at the top to enable/disable different modes. these will decide what is calced/shown on the various pages.
when you have at least two snapshots that are different, you can diff them together by clicking through the various pages.
it should be straightforward enough. if you spam this website with requests to dos me i will cry about it and such.
comment on the forums thread or somewhere else if you enjoy or have issues, so that i may know.
ps. updating players is heavily rate limited to avoid getting my ip blacklisted :-)
