Performance

Steadfast is faster than OptiFine, thanks to modern performance mods like Sodium, Lithium, and others. The bundled mods have been carefully selected to be safe in your worlds and provide noticeable speed benefits on any device.

Works Everywhere

Steadfast does not include content mods, so you can play on any world or server. While you can use any game launcher to play the pack, we recommend and provide support for specific ones that offer the best experience.

Built on Fabric

Steadfast uses the Fabric mod loader, which is lightweight, fast, and supports a lot of mods. You can use the modpack as a base to add your favorite mods to.

Open Development

Steadfast is open-source, and so are all of its mods. We welcome user suggestions and collaborate with mod developers to create a better user experience for everyone.

Helpful Community

We have a growing community of steadfast academy members who enjoy playing the pack and helping each other.

Frequently Asked Questions

Steadfast server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Steadfast server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to Steadfast without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Steadfast server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
