Minecraft launcher + PvP mod
A launcher that sets everything up for you, and an in-game mod with 67 modules, from 1.8.9 to 26.3. Premium or non‑premium, everyone plays.
Premium or non-premium
Got a Minecraft account? Sign in with one click. Don't have one? Pick a name and hit play. Nobody gets left out.
Pick a name and play right away, in single player and on non‑premium servers. Add as many accounts as you like, premium and non‑premium mixed, and switch between them in one click.
For premium servers and your official skin. You sign in on Microsoft's own page, in your browser: OkaClient never sees your password.
Optimized and boosted: FPS and memory
On first launch, OkaClient analyzes your machine and sets Minecraft up for it. After that, you just click PLAY.
Your processor, memory, graphics card and Java are analyzed on first launch. Minecraft's RAM is set to match your PC.
Generational ZGC if your PC has 6 cores or more (Java 21+), G1 tuned for smaller setups, compact object headers with Java 25.
Sodium, Lithium, FerriteCore, Entity Culling, ImmediatelyFast and Dynamic FPS are offered on first launch, matched to your version.
The launcher downloads Mojang's official Java for your Minecraft version, and checks every file.
Pick "Close launcher completely": the launcher quits when the game starts and comes back on its own when you close it.
Fewer frames per second while the game is in the background, lighter distant scenery, "Optimise video" in one click. Players and mobs are never hidden.
No "+300 FPS" claims here: the gain depends on your PC and your mods. We'd rather tell you exactly what OkaClient does.

The OkaClient mod
Press Right Shift in game: HUD, PvP, visuals, quality of life… Turn on what you want, tweak everything, move everything. From 1.8.9 to 26.3, with Fabric (Legacy Fabric on 1.8.9 and 1.12.2).
33 versions The mod runs from 1.8.9 to 26.3, 1.8.9 included for PvP. See supported versions
Keep up to 20,000 messages in game, versus 100 in the base game. The chat is saved on your computer, server by server, and the conversation picks up where it left off when you come back. Scroll back as far as you like, or search with Ctrl+F.
Invisible players show up see-through, just like the game already does for your team-mates. Nothing else is revealed: no name, no outline, no hitbox.
A free camera that doesn't go through blocks and stays close to your character. Meanwhile, your character doesn't move, hit or use anything.
Hold C to zoom, use the scroll wheel to adjust. Adjustable magnification, optional smooth zoom.
Drop a waypoint with B, find them all with J: they show up in the world and on the minimap. The minimap shows the terrain, with no radar and no players.
FPS, CPS, coordinates, keystrokes, armor, effects, ping… 23 elements to place wherever you want, each with its own style: background, border, colors.
See clearly in the dark: caves, nights, the depths. Flip a switch and everything lights up.
Private messages, mentions of your name and friends coming online pop up as small toasts, no digging through the chat.
Right Shift opens every module: search, toggle, tweak. Up top, performance mode: fewer frames per second in the background, lighter distant scenery, "Optimise video" in one click.
Pick one of 10 presets or draw your crosshair pixel by pixel, on a 15 × 15 grid.
Main menu, a pause menu with your server and your shortcuts, loading screen: the whole game in OkaClient colors.

Security
Before every launch, the launcher checks the profile's mods, packs and shaders. Cheat clients, x-ray and wall-hack freecams are quarantined: nothing gets deleted, everything is listed. The mod runs the check again when the game starts, then every 15 seconds.
Every launcher and mod update is described in a signed manifest (Ed25519). The launcher checks the signature, the size and the SHA-256 fingerprint before installing anything.
Modrinth mods checked with SHA-512, Java and game files checked against their fingerprint, everything over HTTPS. An interrupted download never leaves a half-written file behind.
Microsoft sign-in in your browser, tokens encrypted by your operating system, and tools that inject themselves into Java are blocked when the game launches.
No third-party tracking tool, and this website has no cookies and no trackers. OkaClient only sends anonymous statistics (versions, system, features used), with no username and no IP address: you can turn it all off in Settings.
No client-side anti-cheat is unbreakable: OkaClient is a first line of defense, and servers keep their own.
Partner servers
Live status in the launcher, a Join button that starts the game and connects you, servers pinned at the top of the multiplayer list and shown on your Discord status.

That's expected for now: the OkaClient installer isn't signed with a certificate yet, so SmartScreen doesn't recognize it. Click "More info", then "Run anyway". If you want to be sure about the file, compare its SHA-256 fingerprint with the one on this page.
The app isn't signed by Apple yet. Right-click OkaClient, then choose "Open". If macOS says the app is damaged, type this in the Terminal:

FAQ
Yes. The OkaClient launcher and mod are free, on Windows, macOS and Linux.
Yes. Pick a username: you can play single player and on non‑premium servers. For premium servers and your official skin, sign in with your Microsoft account. You can keep several accounts, premium and non‑premium, and switch between them in one click, even in game.
The launcher installs Minecraft Java versions with Vanilla, Fabric and Forge in one click (snapshots optional); NeoForge and Quilt come with modpacks. The OkaClient mod runs on 33 versions, from 1.8.9 to 26.3: 1.8.9 and 1.12.2 with Legacy Fabric, then 1.16.4 to 26.3 with Fabric.
Yes. Windows 10 and 11 (64-bit), macOS 12 Monterey or later (Apple Silicon and Intel), and 64-bit Linux (AppImage, .deb package or .tar.gz archive). No need to install Java: OkaClient downloads the right Java for your Minecraft version.
OkaClient does what actually helps: memory and garbage collector (ZGC or G1) tuned for your PC, performance mods offered on first launch (Sodium, Lithium, FerriteCore, Entity Culling, ImmediatelyFast, Dynamic FPS) and an in-game performance mode. The gain depends on your PC and your mods: we don't promise a number.
It isn't cheating. The minimap shows the terrain with no radar, no players and no caves; the freecam doesn't go through blocks and your character can't do anything while you use it; coordinates are hidden when the server requires it. A server can also turn off any module for its own game. As with any client, follow each server's rules.
Like them, OkaClient adds PvP and quality-of-life modules in game: HUD, CPS, keystrokes, zoom, custom crosshair… On top of that, it accepts premium and non‑premium accounts, installs Fabric, Forge and Modrinth content in separate profiles, and its mod runs from 1.8.9 to 26.3. OkaClient is not affiliated with Lunar Client or Badlion Client.
Every update is signed (Ed25519) and verified before it gets installed, and the download section shows the SHA-256 fingerprint of every file. Windows shows "Windows protected your PC" because the installer isn't signed with a certificate yet: click "More info", then "Run anyway".
Yes. Each profile has its own folder: its version, mods, settings and worlds. Modrinth is built into the launcher (Fabric, Forge, NeoForge or Quilt mods, shaders, resource packs, data packs, .mrpack modpacks) and the OkaClient mod is added to Fabric profiles, compatible with Sodium, Lithium and friends. When the anti-cheat blocks a file, it quarantines it: nothing gets deleted.
Servers featured in the launcher and in game, with their live status and a Join button that starts the game and connects you: SurvieTikTok (mc.survietiktok.fr) and OneChunk (play.onechunk.fr). Got a server? Talk about it on the Discord.
Automatically on Windows and with the AppImage: the launcher checks for new versions, downloads them, verifies the signature and the fingerprint, then installs them; the mod follows the next time you start the game. The .deb package just asks you to confirm, and on Mac updates are built into the launcher.
Only anonymous statistics, to know how many players use OkaClient, on which versions and with which features: no username, no IP address, and you can turn them off in Settings › Send anonymous statistics. While you play online, the OkaClient badge sends your username and UUID to OkaClient's service. A crash report is only sent if you click to share it. This website has no cookies and no trackers.
On OkaClient's Discord. If the game crashes, the launcher's diagnostics put together a report you can share, without your sign-in tokens.
