- Lunar Client is free and built by Moonsworth around PvP performance and cosmetics, not combat automation.
- Opal is $8.99 and ships 70 modules, split between a blatant set tuned for BedWars/SkyWars-style combat and a quieter set built to hold up on most other servers.
- These aren't really competing for the same job: Lunar keeps you inside normal, allowed mod territory, Opal automates the fight.
- Lunar's cross-version reach genuinely wins, spanning the 1.7 era through the modern 1.21 line. Opal targets MC 26.2 only.
- Opal embeds a full GraalJS scripting engine and a custom glass UI engine, a build-your-own-tools story Lunar's documented feature set doesn't attempt.

Opal by the numbers
Free and legit vs $8.99 and built for combat
Lunar Client costs nothing. It's maintained by Moonsworth, ships a curated mod set, a custom launcher, and an in-house cosmetics marketplace, and it's kept actively current. For a lot of players that's the whole pitch: free, polished, and it stays inside mod territory servers actually allow.
Opal costs $8.99. What that buys is a different kind of product: 70 modules split across combat, movement, visual, world, and utility, a custom glass UI engine, and combat tools tuned specifically for BedWars/SkyWars-style modes. Lunar hands you a clean, curated bundle. Opal hands you a client built to win fights.
Cheat client vs legit client: not the same category
Based on its own documentation, Lunar Client's feature set is aimed at performance and cosmetics: curated mods, a launcher, a cosmetics marketplace, and cross-version play. Nothing in that list resembles automated combat, and that's a legitimate, respected lane to occupy.
Opal is built the other way around. Its module set splits into a blatant category (flight, scaffold, aggressive combat) tuned for BedWars/SkyWars-style modes, and a quieter ghost category (subtle aim, reach, velocity adjustments) built to hold up across most other servers. If you want a client that stays inside normal, allowed mod territory, Lunar is doing that job well. If you want a client that automates the fight, that's what the $8.99 is for.
Cross-version reach: Lunar's real advantage
This one goes to Lunar outright, no hedging. Its documented cross-version support runs from the 1.7 era through the modern 1.21 line, a genuinely wide spread for a single client. Opal targets MC 26.2 only, as a Fabric mod, current version and nothing older.
If you bounce between legacy PvP versions and the current release, or you play on servers still running older Minecraft builds, Lunar's range covers ground Opal simply doesn't try to.
Scripting and UI: where Opal spends its price
Lunar Client's documentation describes a curated mod bundle and a custom launcher. No scripting layer or extensibility story on file, which is fine when the product's job is "install and play," not "build your own tools."
Opal embeds a full GraalJS scripting engine: scripts can be loaded and unloaded against the client's player, render, rotation, world, and module APIs at runtime, no recompiling required. The UI itself is a custom glass UI engine built on Minecraft's Blaze3D rendering pipeline, with blur, fresnel, refraction, and shadow effects, laid out through GraalJS and Yoga. That's the kind of engineering $8.99 is paying for, not a gap in Lunar's design, just a different product.
When Lunar Client is the better call
Be honest with yourself about what you actually want.
Pros
- You want free and you're not looking for combat automation
- You move between old and current Minecraft versions, from the 1.7 era through 1.21
- You want to stay inside normal, allowed mod territory instead of running cheat modules
- You want an in-house cosmetics marketplace and a launcher that's been polished for years
Cons
- No combat automation in the documented feature set, so BedWars/SkyWars fights get no help
- No scripting or extensibility layer on file if you want to build your own tools
- Locked to Lunar's own curated bundle rather than a quiet, tunable ghost set
If you're fighting in BedWars or SkyWars-style lobbies and want a client tuned for that combat out of the box, and $8.99 isn't a barrier, that's Opal.
