The Site is under development and thus might change/have its data wiped often.
Newest site update introduces historical user stats for vehicles (Graphs), a new table to show vehicle stats, a new API (Was already public) and some further updates to come.
The API is still free to use until my disk gets full and it all burns down. (The API endpoints with 'Direct' in their names doesn't cause an increase in data storage as the data is never saved.)
