Eaglercraft — 121 10

This is the most common question. Short answer: The project operates in a legal gray area.

The original Eaglercraft code does not include Mojang's assets (textures, sounds, names) in the distributed files. Users must provide their own Minecraft assets (usually by extracting them from an official purchased copy). However, many public online "play now" sites do include those assets, violating Mojang's EULA.

For legal safety:

Mojang has historically not pursued individual users of browser-based clones, but they have taken down popular distribution sites.

Eaglercraft 1.2.1 v10 is the best version of browser-based Minecraft from the pre-1.3 era. Build 10 fixes the worst multiplayer sync issues of earlier builds while keeping the incredible accessibility. It's not perfect—the lighting bugs and server limitations are real—but for a free, legal* web port of an old version, it's a technical marvel.

Final Score: 8.5/10
Highly recommended for casual play, school LANs, and nostalgia trips.

Note: Eaglercraft is not endorsed by Mojang. It uses recompiled Minecraft assets, so its legal status is gray. Play at your own discretion.
