One sticking issue with GOG currently is GOG Galaxy, and how it has no support for Linux. Now the Comet project aims to bridge the gap.

The aim of Comet is to eventually get it to work with projects like the Heroic Games Launcher and Lutris, to get their GOG support into even better shape with Wine / Proton on desktop Linux and Steam Deck. So in a way you could compare it to Legendary for Epic Games, giving a minimal and platform agnostic SDK.

A developer reached out to note they're now after more testers to play around with it, specifically on desktop Linux with Steam Deck testing planned later on.

So Comet will provide support for the likes of achievements, stats, friends, leaderboards and more. It's not finished yet of course, with some features under development and some not there at all yet but it's impressive work and continues to be an example on how the FOSS community are showing certain companies how it's done with a little community effort.

See more on the GitHub.

I'm curious if the linux gog client Minigalaxy will use this too.
It seems like they know about Comet already https://github.com/sharkwouter/minigalaxy/issues/361
I hope they can start working on integrating it once it's more stable.

big question:

does it actually (aim to) allow a game to have achievents tracked and sent to GoG's cloud when played under linux?

or does/will it serve only to show what's stored there from play sessions under windows (or WINE) with GoG Galaxy itself?

The big question here is if Comet handles GOG Galaxy's multiplayer functionality. That's the only thing I'm really missing that I'm unsure if Heroic covers already. I don't really care about achievements that much by comparison.

The SDK is to allow games to access those online services, like article says to enable achievements, leaderboards stats and friends in unofficial launchers.

Yeah I think that will not work. The Linux builds on GOG.com do not have these features implemented in the first place.

Unless this project aims to support the Windows games in Wine / Proton as well. That might work.

There's current windows versions of GoG games which are likely to be able to use it, and hopefully new linux builds might be able to leverage this despite not being official?

Sadly GOG doesn't provide GOG Galaxy SDK builds for Linux. The only game that does somehow has it is Stardew Valley.

Nothing we can do about it unless we convince GOG to release SDK for Linux.

Exactly as stated in the article FYI. For Wine / Proton.
