- Raven B3 runs on MC 1.8.9 through Forge. Opal runs on MC 26.2 through Fabric. There's no overlap, so this isn't a "which is better" question until you know which version you're launching.
- Opal is $8.99, actively maintained, and ships 70 modules through a launcher. Raven B3's public record stops at version, loader, and author, with no listed module count or active update cycle.
- Still on 1.8.9 for old PvP servers or legacy anarchy? Opal isn't an option there. Raven B3 is exactly what runs.
- Raven B3 and Raven B++ share a name and nothing else. Different author, different lineage, easy to mix up in a search result.
- On current Minecraft, Raven B3 can't follow you. It stays exactly where its build was frozen.

Which Minecraft version you're actually playing
That's the real question here, not which client is "better." Opal runs on MC 26.2 through Fabric. Raven B3 runs on MC 1.8.9 through Forge. There's no overlap between the two, so there's no real choice to make until you know which game you're actually launching.
If you're still on 1.8.9, for old PvP servers, legacy anarchy, whatever keeps people on that version, Opal simply doesn't target that client version at all. Raven B3 is what runs there. If you're on current Minecraft, Raven B3 can't follow you. It stays exactly where its build was frozen back in the 1.8.9 era.
What's actually documented about each client
Opal's record is the kind you can build a spec sheet from: 70 modules split across combat, movement, visual, world, and utility categories, a custom glass UI engine, and an embedded GraalJS scripting engine you can load and unload scripts into while the client is running. Flight and scaffold are two of the specific modules on offer, covering movement and bridging respectively, and the combat set ships its own aim-assist targeting alongside a KillAura module.
Raven B3's record is thinner: a Forge mod for MC 1.8.9, part of the Raven lineage, built by blowsy, marked legacy. No module list, no price, no UI details survive in what's citable about it. That's not a knock on the client itself, the 1.8.9 scene has produced plenty of clients worth respecting. It's just a statement about how little of this one is written down anywhere we can point to. We're not going to guess at features it might have, and blowsy's work deserves better than a made-up spec sheet.
Installing a mod yourself vs a launcher
Opal ships through a launcher: log in, it pulls the current build, you play. That's the entire setup, and it's how the client stays current on MC 26.2 without you doing anything else.
Raven B3, per its own record, is a Forge mod: install Forge, drop the jar in, manage it the way client jars from that era generally worked. Its legacy status means there's no update cycle running behind it anymore, so whatever build you find is the one you get. If you already know your way around a 1.8.9 mods folder, that's a five-minute job. If you don't, "install as a Forge mod yourself" is doing a lot of quiet work in that sentence.
Which Raven you're even looking for
Worth flagging before you go searching further: Raven B3 isn't the only Raven-named client out there.
Two different Ravens
The client documented here is Raven B3, by blowsy. Raven B++ is a separate, unrelated client by K-ov. Same naming pattern, different projects, different lineages. If a search result mixes the two up, they aren't the same thing.
When Raven B3 is the better call
Be honest about which version you're actually playing.
Pros
- You're still playing on MC 1.8.9 and need a client that actually runs there
- You want a period client from the 1.8.9 scene, not a modern rebuild
- You're specifically after the Raven lineage by blowsy, not Raven B++
Cons
- No module list, price, or UI details are documented anywhere citable
- Legacy status means no active updates behind whatever build you find
- You install it yourself as a Forge mod, there's no launcher
- Doesn't run on MC 26.2 or any current-version content
If you're set on current Minecraft and want a maintained client with a documented feature list, a real UI, and a launcher that logs you straight in, that's Opal.
