ajour VS Playnite

I miss the ajour client...

However if privacy is a concern there are some open source alternatives you can find like Ajour (https://github.com/ajour/ajour).

Project I am talking about: https://github.com/ajour/ajour

The best desktop app in Rust that I used was ajour (polished, self-contained portable exec., auto-update, ...)

Bad news tho...

At the time of this sale, a lot of apps (Cursebreaker, Ajour) started popping up, which utilized the Curseforge api to pull addon packages down, thus skirting around Overwolf's application. Fast-forward to a few months ago, Overwolf announced they were reworking the API. This required developers to apply for access, and even if approved, addon devs controlled whether the packages were accessible via the API. Curseforge uses ads to payout developers who host there, so rightfully so, skirting around the Overwolf app wasn't acceptable to them anymore. With these changes, developers of these apps ceased worked on them.

unfortunately Ajour no longer has support.

Well. For now, I would just recommend Ajour, which is probably the best addon manager out there. It's really simple, lightweight, has no ads, updates all of your addons in mere seconds, and it can even update weakauras from wago.io. It can download from Wowinterface and the Tukui website too, so you can use it to update ElvUI.

These issues are the main reasons why Ajour's developer decided to quit.

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.
