Basics
Is Sour Client free?
Yes. Every mod, the HUD and every performance improvement are free. Sour Gold is optional and covers cosmetics and theming only; it never changes how the game plays.
Do I need to own Minecraft?
Yes, on a Microsoft account that owns Minecraft: Java Edition. The game files come straight from Mojang, the same way the official launcher gets them.
Which versions are supported?
1.8.9 on Forge, with every module, render tier and cosmetic, and 1.21.11 on Fabric, with the Sour menus, HUD, cosmetics, friends and Hypixel tools plus Sodium, Iris and a tuned performance pack. Pick the version when you make a profile. Other vanilla versions also run, without Sour Client on top.
Is there a Mac or Linux build?
Windows 10 and 11 only for now. Mac and Linux have no date yet; news goes on the changelog.
How do I install it?
Download the installer, run it, and it sets everything up. Open the launcher, sign in with Microsoft and press Play. Java comes with the launcher. The download page walks through every step.
Who makes Sour Client?
An independent developer in New Zealand. Sour Client is not affiliated with Mojang, Microsoft or any other client. More on the About page.
Gold
What is Sour Gold?
The paid plan. Upload your own image as a cloak, a gold name with more colours the longer you hold it, launcher themes, no ads and a store discount. Monthly, yearly or a single lifetime payment. Everything is on the Sour Gold page.
How do the unlockable name colours work?
Your Gold name starts with the classic gold mark. The longer you hold Sour Gold, the more colours unlock to pick from, in your account centre.
Does it give a gameplay advantage?
No. Sour Gold is cosmetic.
Why is lifetime limited?
Lifetime is a one-time payment that keeps Sour Gold on your account across every version. Only 100 will be sold.
Can I cancel?
At any time. You keep Sour Gold until the end of the period you paid for.
How does payment work?
Choose a plan, enter the Minecraft account it is for, and pay at checkout. Payment is handled by Stripe, which keeps your card details. Gold switches on as soon as the payment clears. Details are in the terms.
Setup
Windows says the installer isn’t safe
Windows shows this box for any new app it doesn’t know yet, so it’s normal.
Click More info, then Run anyway.
To check the file: download only from sourclient.com, scan it on VirusTotal, or run Get-FileHash SourClient-Setup.exe in PowerShell and compare it with the checksum on the download page.
Does it see my password?
No. You sign in on Microsoft’s own page and Sour Client receives only the sign-in token Microsoft returns. The privacy policy lists what is stored.
Is Sour Client affiliated with Mojang or Microsoft?
No. Sour Client is independent. It is not an official Minecraft product and is not approved by or associated with Mojang or Microsoft. The disclaimer has the full wording.
Is it a cheat client?
No. It has no reach, aim assist or auto-clicker.
What about OptiFine?
Add your OptiFine 1.8.9 jar to the launcher once and it is installed into every profile. 1.21.11 comes with Sodium and Iris installed.
Can I import my setup?
Yes. The launcher imports profiles, settings and resource packs from Lunar, Badlion and the vanilla launcher.
Cosmetics
Can I use my own image as a cloak?
With Sour Gold. The built-in cloaks are free for everyone.
Who sees my cloak?
Everyone on Sour Client, and you see theirs. Cloaks are cached as they load, so your frame rate holds steady when new players walk past.
Are uploaded cloaks checked?
Every upload is checked before anyone else can see it. Sexual content, gore, hateful imagery, terrorism, self-harm and copies of official Minecraft capes are refused. You choose what you see (strict, standard or everything), and any player can report a cloak. Full rules in the content policy.
Can I see other players’ stats?
Search any username on the players page. You decide what shows on your own card, or hide it, in the account centre.
