I use EDDI and occasionally EDDiscovery. EDDI has a nice voice feature allowing me to stay tabbed out on the 300k+ ls trips; EDDiscovery is very strong when it comes to exploration.

Both can submit to EDDN, Inara, and EDSM. EDDis also submits to Edastro.

There's seriously a lot of data that gets posted to EDDN like docking status. Theoretically this stuff is all tactically useful, but the only tool making use of it (that i know of) is https://github.com/inorton/EDMCHits, an EDMC plugin.

Good to see the hardpoint map back somewhere online!
