Opal vs Meteor Client: Minigame PvP vs Free Anarchy Client

At a glance

Free and open-source vs $8.99 and closed

Meteor Client costs nothing. It is licensed GPL-3.0, the full source sits on GitHub under MeteorDevelopment, and the project runs on donations instead of sales. If you want to read the code, fork it, or just never pay for a Minecraft mod, that is a legitimate reason to pick it, and we are not going to pretend otherwise.

Opal costs $8.99, and the source is not public. What that buys is a finished product built around a launcher: log in, launch, play, no Fabric install or mappings to think about. You are paying for the work of assembling and maintaining that, not for the option to read the source.

Built for different fights: minigames vs anarchy

This is the real split, and it is worth saying plainly instead of manufacturing a rivalry that is not there. Meteor Client is built for anarchy servers such as 2b2t, where there is effectively no anticheat and the module set leans into automation, base finding, and crystal or anchor combat instead of evasion. By its own scope it is not a ranked-PvP or minigame cheat, and per its own documentation it is detected trivially by the server-side anticheats that Hypixel-style servers actually run, because that fight was simply never the point.

Opal is built for the opposite environment: BedWars/SkyWars-style minigame combat, with a loud feature set for that fight and a separate quiet set aimed at holding up across most servers. Neither client is really trying to do the other's job, and pretending otherwise would undersell both of them.

Module count: 70 vs around 150

Meteor Client ships around 150 modules across combat, movement, player, render, and world categories, and a chunk of that number is anarchy-specific automation Opal does not attempt at all: a highway builder, a stash finder for locating bases, multi-instance bot coordination. It also ships a documented addon API, so the real ceiling on what you can run is higher than the base count once the community addon ecosystem gets counted in. Credit where it's due.

Opal ships 70 modules across combat, movement, visual, world, and utility, narrower by design and aimed squarely at minigame combat, movement, and a quiet set rather than anarchy automation. Fewer modules, but every one of them is pointed at the same job.

UI and setup

Opal runs a custom interface: a custom glass UI engine built on Minecraft's Blaze3D pipeline (blur, fresnel, refraction, shadow effects) plus a GraalJS/Yoga UI runtime driving things like the dynamic island overlay. It arrives through a launcher, so there is no manual mod install to get right.

Meteor Client's standout UI feature is its Starscript-driven HUD, which lets you script live values straight into HUD text instead of picking from fixed presets. That is genuinely clever design. It is a Fabric mod, though, so setup means installing Fabric Loader and dropping the jar in yourself, a fair trade for free and open-source, but still a step Opal skips entirely.

When Meteor Client is the better call

Be honest with yourself about what you actually play.

If you want a client built for minigame PvP with a polished UI and a quiet set for most servers, and $8.99 is not a barrier, that is Opal. If you are on anarchy servers and want automation Opal was never built to offer, Meteor is the right tool for that job, not a lesser one.
