classic.minecraft.net downloads 0 GB. No launcher, no installer, no Microsoft account — the page generates a world while it loads. That is the entire free browser route, and it is official: Mojang put the 2009 build back online for the game's tenth anniversary.
What it does not give you is a memory slider. You cannot allocate RAM to a browser tab, so your levers sit elsewhere: hardware acceleration, the tabs running behind the game, and the size of the window. `-Xmx` only enters the picture when you move to the launcher — and there, 4 GB beats 12.
The browser version costs you 0 GB and no account
Minecraft Classic runs at classic.minecraft.net. Nothing downloads, nothing installs, and no Microsoft account is asked for — the world starts generating as the page loads.
You get build 0.0.23a_01, the 2009 version. 32 blocks, creative only: no mobs, no health bar, no crafting, no survival. Sixteen materials, sixteen wool colours.
What the tab asks of your machine
- a current browser with WebGL: Chrome, Edge or Firefox
- hardware acceleration left on, which is the default
- a physical keyboard — there are no touch controls, so your phone is out
- roughly 1 GB of free memory, not 8
I keep a five-year-old laptop on the shelf because it is the machine that gets stuck. Classic is one of the few things on it that opens in seconds. That is the point of this route.
Multiplayer left the browser version in 2025
Classic is solo now. Mojang disabled the shared-link multiplayer on 8 May 2019, then removed it outright in the 9 June 2025 update.
Old join links no longer resolve. Any page still promising nine players in a shared Classic world is describing a feature that no longer exists.
Playing free with other people is a different route entirely — the launcher, a free server, or another game. We keep that mapped out separately, because none of it happens in a tab.
The browser tab is your RAM setting — three levers, in order
You cannot allocate memory to a browser game. There is no `-Xmx` in a tab: the browser hands out RAM itself, and your only lever is what else is competing for it.
Check your own numbers, in two shortcuts
- Shift+Esc in Chrome or Edge opens the browser's task manager, memory listed per tab
- chrome://gpu must read "WebGL: Hardware accelerated" — if it says software, your problem is the GPU path, not your RAM
- Settings → System → Use graphics acceleration when available: on
What actually buys frames
- close the other tabs before you start; each one holds memory you are not using
- play windowed at 1280×720 rather than fullscreen at 1080p — fewer pixels, identical build
- a second screen playing video costs you more than Classic does
On my desktop, Classic was never the largest line in that task manager. On the old laptop it was, the moment fifteen tabs sat behind it. The fix was the tabs, not the game.
Try Minecraft Classic — free, in your browser, 0 GB
Official Mojang page. It opens in the tab you are already in: no launcher, no account, and nothing written to your disk.
https://classic.minecraft.net →Allocated RAM starts to matter the moment you leave the browser
`-Xmx` lives in the launcher, not the tab. Path: Launcher → Installations → your version → ... → Edit → More Options → JVM arguments.
The string begins with `-Xmx2G`. Change that number and nothing else.
How much, by machine
- 8 GB system: `-Xmx3G`. Windows and your browser need what is left.
- 16 GB system: `-Xmx4G`. That covers vanilla and most light mod lists.
- Heavy modpacks: `-Xmx6G`, and rarely more than that.
More allocated is not more frames. Past what the game actually uses, you lengthen garbage-collection pauses and starve the OS — the stutter people blame on their graphics card.
Mojang raised the Java Edition requirements on 21 July 2026, the first time in seventeen years: 8 GB of RAM minimum, 12 GB on integrated graphics, 16 GB recommended, a Vulkan 1.3 GPU with 2 GB of VRAM — and 1 GB of disk. The disk figure is the one that did not move.
Where the free browser route stops
Three walls, and the way out of each.
- You want survival, mobs and crafting. The browser cannot give you them. The free trial does, for about 100 minutes of play, and that route runs through the launcher.
- You are on a Chromebook or an integrated-graphics laptop. Classic is fine there. Full Java Edition, under the July 2026 minimum, is not — check the VRAM line before you plan around it.
- You found a browser port running 1.8 or 1.12. Those are Eaglercraft-family builds. Mojang sent DMCA takedowns from 2022 onward and the main repositories came down; playing a copy of a game you do not own is infringement, not a free tier. Stay on classic.minecraft.net.
I tested the same three walls on the shelf: the old laptop, the current desktop, and a phone with 4 GB of storage left. Only the phone failed outright, and it failed on the keyboard, not the memory.
The free Minecraft routes on PC, by what they cost your disk and your memory
| Route | Download | Disk | Memory in use | What you get |
|---|---|---|---|---|
| Minecraft Classic (browser) | 0 GB | 0 GB | ~1 GB in the tab | Creative, 32 blocks, solo, no account |
| Java free trial (launcher) | ~1 GB | 1 GB min | -Xmx2G by default | ~100 minutes, free Microsoft account |
| Full Java Edition (paid) | ~1 GB | 1 GB min | -Xmx3G to 4G | Survival, servers, mods |
| Unofficial browser ports | 0 GB | 0 GB | 1–2 GB free advised | DMCA'd since 2022 — not a route to take |
