SteamCMD-GUI VS Playnite

However, Steam has been long offering https://developer.valvesoftware.com/wiki/SteamCMD (command line, no UI) as an alternative to normal Steam Client so you can install that (replaces the current) and add either https://github.com/dmadisetti/steam-tui or https://github.com/DioJoestar/SteamCMD-GUI that uses SteamCMD but offers a functional UI, the alternative you're seeking for.

I know Steam/SteamCMD is not open-source, but I've been curious as to the limitations of the program. A lot of people often complain about the Steam client, and while I personally like it for what it is, I feel like a lot of people might get appeasement if a more open-source program was made. I'm mainly just curious if that's actually possible, or if SteamCMD's limitations are to where it can only do the basic stuff that this program does. Most info I can readily find online is stuff from about 10 years ago, so I don't know how much has changed since then. I know it's mainly meant for servers, but in theory it could be repurposed if it has a lot of the same featureset.

Lucky for you, https://developer.valvesoftware.com/wiki/SteamCMD still works as the No-UI command line interface that's sole purpose is to act as a DRM-checking layer that is stripped from all the bloatware latest Steam Beta offers in the name of fancy. And if you combine that https://github.com/dmadisetti/steam-tui or https://github.com/DioJoestar/SteamCMD-GUI, you'll get yourself a still functional and manageable but not so good looking DIY Steam Client, totally legit.

What can you do? Luckily so far https://developer.valvesoftware.com/wiki/SteamCMD (Command Line UI) is still working for the lowest consumption and Players are fighting to keep it alive via Projects like https://github.com/DioJoestar/SteamCMD-GUI or https://github.com/dmadisetti/steam-tui but I'm pretty sure that stupid developer will also convince Gaben to get rid of them sooner or later.

I don't think there will be any SteamLite, but for your purpose, you can try SteamCMD: https://developer.valvesoftware.com/wiki/SteamCMD For GUI: https://github.com/DioJoestar/SteamCMD-GUI I haven't used it, so I can't tell what problems you might encounter.

I've done something similar before with Playnite (an open-source PC game library manager), which has an HLTB plugin.

Playnite: The one with the most features and libraries available via addons and has a lot of options for customization. In my opinion the best one available for this purpose.

Here's a project for Playnite 11: https://github.com/JosefNemec/Playnite/milestone/9

As for my LGO, the only other app I've installed outside of the standard launcher was Playnite to consolidate all games into one place as Legion Space doesn't detect everything I have installed and I don't want to manage manually adding games to their launcher.

use playnite instead of the individual launchers.

Here is where I come in and recommend everyone check out Playnite: https://playnite.link/

When I care about supporting a developer or publisher and they offer their product on their own storefront DRM-free, I will often go there to buy. Or I buy from GoG which takes a smaller cut. Playnite lets me launch my Steam and non-Steam games in a seamless fashion. Steam still does a great job as a game installer/patch manager, and helps me discover new games. But I'm not locked into paying them a 30% fee, which is pretty brutal for some smaller publishers.

For anyone with any of the myriad of HDR monitors that prefers to leave desktop mode in SDR RGB, I just discovered that the excellent Playnite game launcher has a feature where you can enable HDR on a per-game basis. Simply tick the "Enable HDR support" option under "Advanced" tab for the settings of the games that you want HDR turned on for. I was previously using the now-abandoned AutoActions for this, so glad to see there's an alternative in a tool I already use.

Not exactly what you are looking for, but I've been using Playnite to launch everything on my computer for years.
