Launcher comparison
SynCraft vs GDLauncher
Two modern Minecraft Java launchers with Rust underneath. GDLauncher (especially the Carbon rewrite) has focused on polishing the launcher experience and tight modpack integration. SynCraft takes the same native-app starting point and adds a built-in local server dashboard. Here's how they compare.
TL;DR
- Pick GDLauncherif you want an open-source, narrowly focused modern launcher and you don't plan to host your own server.
- Pick SynCraft if you want the same modern-launcher feel but also need to run a Minecraft server for friends — managed from the same app.
- Both install side-by-side without conflict; they store instance data in their own folders and share Mojang's authentication flow.

Where GDLauncher wins
- Open source, modern stack. GDLauncher Carbon is a Rust + Solid rewrite that you can inspect, fork, and contribute to. SynCraft is closed source today, so if open source matters for your setup, GDLauncher is the right pick on that axis.
- Narrowly focused launcher experience. Fewer features often means fewer things that can break. If everything you want is "install a modpack and play," GDLauncher's tighter scope is a positive.
- Established user base. GDLauncher has been around longer than SynCraft and has a larger community of users and forum threads to reference when something goes sideways.
- Polished modpack flow. The modpack browsing UI in GDLauncher is widely praised. If that's the feature you use most, GDLauncher does it well.
Where SynCraft wins
- Built-in local server dashboard. GDLauncher is a client-only launcher. SynCraft is too, plus it manages a local Minecraft server: a 7-step Vanilla / Paper setup wizard, a live RCON console, player management (ops, whitelist, bans), and a server.properties editor — all inside the launcher.
- Wider modpack source coverage. SynCraft browses Modrinth, FTB, and CurseForge, plus local .mrpack imports. GDLauncher covers the big two but not FTB directly.
- All four modern loaders, consistently. SynCraft installs Fabric, Quilt, Forge, and NeoForge through their official installer pipelines with live logs, which makes troubleshooting a broken install much easier than when loader installation is opaque.
- Built-for-server-ops feel. If you've ever wanted to change a property, kick a player, and run an RCON command without opening four different tools, SynCraft is designed for that workflow. GDLauncher is designed for a different workflow.
The honest caveat
GDLauncher Carbon is open source. SynCraft is free but not currently open source. For users who prefer to run auditable software — or who want insurance in case the primary author stops shipping — that's a real tradeoff, and GDLauncher is the stronger pick on that single dimension.
When to pick GDLauncher
- You want a focused, modern, open-source launcher.
- Your workflow is "install a modpack and launch."
- You don't host or plan to host a local server.
- You appreciate a larger existing user base and community.
When to pick SynCraft
- You run or want to run a local Minecraft server for friends.
- You want RCON, ops / whitelist / bans, and server.properties editing without opening a terminal.
- You install modpacks from more than just Modrinth and CurseForge.
- You want one tool instead of a launcher + a server manager + a config editor.
FAQ
- How is SynCraft different from GDLauncher?
- The headline difference is scope. GDLauncher (including the newer Carbon rewrite) is a focused client-side launcher — it installs loaders and modpacks and runs the game. SynCraft does all of that and adds a built-in local Minecraft server dashboard with a 7-step setup wizard, RCON console, ops/whitelist/bans, and a server.properties editor.
- Are both free and cross-platform?
- Yes. Both are free to download and run on Windows, macOS, and Linux. SynCraft ships a Windows NSIS installer, a macOS DMG, and Linux AppImage / Debian packages. GDLauncher distributes standard installers for each platform as well.
- Is SynCraft open source like GDLauncher?
- No. GDLauncher Carbon is open source. SynCraft is free to use but the source is not currently public. If open source is a hard requirement, GDLauncher is the right pick on that axis.
- Which one is better for modpacks?
- Both support Modrinth and CurseForge modpacks natively. SynCraft also supports FTB and local .mrpack imports. If you specifically want a launcher focused purely on modpack browsing with no server features, GDLauncher fits; if you also want to run the server, SynCraft.
