The fleet report on Capsuleers.app compiles an after-action report from a list of EVE Online pilots and a UTC time window. Type one name per line, pick start and end of the operation, and the tool aggregates into a roll-up the killmails emitted and received by participants in that period, using eve-kill as the data source.
The report shows ISK destroyed, ISK lost, kill/loss and ISK efficiency, top ships killed, top ships lost, top damage dealer, top final blow, a per-battle breakdown with each side's composition, and the effective engagement duration. The result is shareable via unique URL to post in your corp Discord channel or alliance channel.
It's the natural complement of the Fleet Ops tool: after a battle copy the tracked-members list, paste it here and get the report. The page is public and works without login, but the integrated fleet tracker requires a linked character with fleet scopes.
