No download · no install
CarrotCraft loads as an ordinary web page, so it runs on locked-down Chromebooks and school laptops where the real Minecraft launcher can't be installed.
Desktop Minecraft needs an installer, a Java runtime and a Microsoft account. On a managed school device you usually have none of those - installation is blocked at the OS level, and that's the end of it.
Eaglercraft sidesteps the problem entirely. It's a port of Minecraft that compiles to WebAssembly and JavaScript, so the whole game runs inside the browser tab you already have open. There is no installer to run, no admin password to enter and nothing written to the device. To the network it looks like an ordinary HTTPS website, because that's exactly what it is.
School Chromebooks are typically low-memory machines, so a few choices make a real difference:
Ready? The launcher page lets you pick version and client, or jump straight to Eaglercraft 1.8.8 - the recommended combination for school hardware.
Play fair with your school. "Unblocked" here means the game is technically able to run in a browser - it doesn't mean your school allows games during class. Check your acceptable-use policy, and save CarrotCraft for break, lunch and home. Getting your account flagged isn't worth a few blocks placed.
This isn't a stripped-down demo. You're joining a full multiplayer network with four gamemodes:
It's free, there's nothing to pay for to be competitive, and you don't need a Mojang account - just pick a username and play.
Some filters block by category or keyword and will catch a gaming site regardless of how it's built. Others allow normal browsing but block the wss:// WebSocket connection the game needs to reach the server, which shows up as the client loading fine but failing to connect.
If that's happening, there's no trick we can offer that doesn't amount to evading your school's filter - and we're not going to suggest that. Play from home or a personal hotspot instead, and see the server IP page for connection troubleshooting that isn't filter-related.
