Best Minecraft Clients: Which One Should You Really Choose?

First, let’s clear up a misconception: in the Minecraft community, “client” can mean two very different things. I am talking about alternative launchers—legitimate software linked to your account. Programs that provide unfair advantages in matches are something else entirely; they are banned on any serious server, and you won’t find them here.

The comparison #

Lunar Client and Badlion are now essentially the same thing #

The acquisition brought two famous names together. In practice, you install the Lunar launcher and from there you can choose to launch either Lunar or Badlion, using whichever game version and memory allocation you prefer.

Lunar Client covers almost all versions, including the most recent ones, and its profiles allow you to use the main mod loaders (Fabric, Forge, and Quilt), meaning you can also use community mods. It comes with about sixty pre-installed and self-updating mods designed for competitive play: an FPS counter, cooldown timers, a minimap where permitted, and cosmetics.

Badlion Client was born in the PvP scene and supports fewer versions, focusing on the classic 1.8 and 1.12 alongside recent ones. Its anti-cheat (BAC) is required for several tournaments. If you play on PvP servers that use 1.8, it remains a standard.

For both, remember two things: you need a regular game account and a service account, and since these are not open-source programs, you can’t verify exactly what they are doing in the background.

Where do FPS come from #

Few people talk about this part. On any client, most of the performance gain comes from a group of mods that rewrite how the game renders the world and uses memory. The most notable are:

• Sodium, which rewrites the rendering engine: it is the single mod that provides the biggest jump, often doubling FPS on modest computers.
• Lithium, which optimizes game logic (creatures, blocks, physics) without changing how they behave.
• Iris, which allows you to use shaders while remaining compatible with Sodium.
• FerriteCore and Entity Culling, which reduce memory usage and the rendering of things you can’t see, respectively.

These are free, open-source, and you can install them on the official launcher in a few minutes or with one click from the Modrinth app. Essentially, an alternative client does this work for you while adding its own interface and cosmetics.

Prism Launcher, for those who want control #

This is the open-source launcher that carries on the legacy of old community projects (like MultiMC) and works with instances: every configuration—with its own version, loader, and mod list—lives in its own folder and doesn’t touch the others.

It is the right choice if:

• you play multiple different modpacks and don’t want them to interfere with each other;
• you want to know exactly what is running on your computer;
• you need a specific old version with a precise set of mods that is easy to replicate and share.

It has no cosmetics or pre-set mods: it installs only what you tell it to, nothing else.

The Modrinth app #

It’s a middle ground: it is the official app of the namesake mod platform. It installs complete collections with one click, updates them, and manages multiple configurations. It is the fastest way to get optimization mods without having to learn how to install them manually, and it is also open source.

Other clients #

Feather Client is the most direct alternative to Lunar: it comes with about forty pre-installed mods, but you can also add any Fabric mods you want, and it includes a system for hosting a small server to play with friends. Some cosmetics and the larger server require payment.

LabyMod is the most flexible when it comes to your on-screen interface: you can move and resize every widget, and it includes friends, voice chat, and cosmetics. It is very popular on German servers and, with LabyMod 4, supports recent versions.

OptiFine is a mod, not a client, but for years it has been the go-to choice for FPS and shaders. It still exists (as of early 2026, the stable version reaches 1.21.11), but it always releases after new game versions and is not compatible with Fabric. Today, Sodium and Iris do the same job, usually better.

The old list also included Cosmic Client and Tecknix Client, which still exist but have much smaller communities, and Batmod, whose official website no longer responds: for PvP, I would stick with Lunar.

How to choose #

• Playing on PvP servers and want built-in conveniences: Lunar Client, with Badlion available right from the same launcher.
• Have an old computer and just want more FPS: the official launcher or the Modrinth app with Sodium and company. It’s free, it’s open source, and it’s the best way to go.
• Want ready-to-go mods but also your own Fabric mods: Feather Client.
• Playing with many modpacks: Prism Launcher.
• Want the simplest thing possible: the Modrinth app with a pre-made optimization pack.

FAQ #

Do alternative clients get you banned? #

Legitimate ones, no: they log in with your regular account and do not provide in-game advantages. However, servers with strict anti-cheat have lists of permitted mods, and certain features, such as minimaps that show players, can be blocked. Read the server rules before enabling them. Mods that provide unfair advantages are a different story and will get you banned.

Are they necessary to play with mods? #

No. With the official launcher, you can install mod loaders and mods with a few extra steps. Alternative clients and management apps save you time, but they don’t make anything possible that wasn’t already.

Are they safe? #

Well-known clients (Lunar, Feather, LabyMod, Prism, Modrinth) are, provided you download them from the official website. The danger lies in copies reposted on third-party sites and “free clients with unlocked cosmetics”: these are among the most common ways to steal Minecraft and Discord accounts.

Do they work with non-premium accounts? #

No, and this guide only concerns the regular game. Legitimate clients require a valid game account linked to your Microsoft account.

How much memory should I allocate? #

For the base game with optimization mods, 4 GB. For heavy modpacks, you can go up to 6 or 8 GB, but always stay well below your computer’s total memory: if you allocate too much, you leave no space for the system and end up with worse stuttering than what you were trying to fix.

Do I need a client on an old laptop? #

You will get much more help from installing optimization mods and lowering your render distance than by changing launchers. On an older computer, the biggest gains come from Sodium and graphics settings, not the client’s interface.
