EDMarketConnector VS icarus

That system doesn’t appear in EDSM. Apparently you are not running an EDDN updater. You should. EDDiscovery, EDDI and EDMC are commonly used tools. They also do lots of other things; the most lightweight variant for just uploading data is EDMC. They can also upload your stats, fleets, materials, discovered systems and whatnot to EDSM and Inara. Those are pretty handy sites, too.

So I strongly suggest icarus, especially if you have a tablet collecting dust (I bought one just for this). Material helper is an absolute must, so is an account on inara.cz.

From my POV, the game has only one major flaw: it became too big, but the UI didn't match that to help the players. Basically: without inara.cz, material helper and icarus, it is just too confusing and hard to get around.

Icarus Terminal is another app that send data to tables in LAN.

I created the API so I could use it with ICARUS Terminal as there aren't any services which provide an API for trade data, but I expect I will build out the website a bit too to add features.

I have released a web front end for this yet (or integrated it into ICARUS Terminal) but it's the only open source version of a currently active service like this, so I thought I'd share it, and the new API documentation for other developers.

More details in the link above, but tl;dr this is in part to support features I want to add to ICARUS Terminal and also to fill a gap left by EDDN shutting down.

This is something I've written, but you might find a use for ICARUS Terminal: https://github.com/iaincollins/icarus

They are ICARUS Terminal :-)

If you have a tablet sitting idle: icarus.

I don't publish a native binary for Linux, but there is a setup guide for ICARUS Terminal for Linux (because I do use Linux and macOS for development) at https://github.com/iaincollins/icarus
