Developer of EVE.rything.org here.
The tool provides up 2 date market-data for all the places and items available (except inaccessible player structures). Everything is built to automatically update to the lates patch - adding new items, changing maketgroups and so on.
It also has a production-planer - in a fairly early state. It may come in handy when you are deciding on producing parts on your own or buying them from the maket.
Now here is my problem: Everything updates by using the esi-api except the blueprints. They only seem to be available within the SDE package. Am i correct? Would it be possible to expose the existing blueprints via the ESI-Api too? It would make things totally autonomous for me - and the application would update even if i’m on holiday, ill or whatever.
