Mainstay SMP Modpack
Modpack for those who want to use all server features
Quick answer
Which Mainstay SMP Modpack release should I use?
Mainstay Minimal edition 1.21.11 is a complete pack release for 1.21.11 with Fabric 0.18.4. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 68 mods in this pack file.
Pack setup
How should I set up Mainstay SMP Modpack for players and a server?
Use Mainstay Minimal edition 1.21.11 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for Mainstay SMP Modpack?
Mainstay Minimal edition 1.21.11. Change the pack release and its contents or setup may change too.
The selected pack release is Mainstay Minimal edition 1.21.11. That file is for Minecraft 1.21.11 with Fabric 0.18.4. It contains 68 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

What kind of pack is Mainstay SMP Modpack?
Mainstay SMP Modpack
Minimal & Full Edition - Client Utility Packs
The Mainstay SMP Modpack is a client-side modpack family designed to unlock the full potential of server-side features, while improving performance, visuals, and quality of life — without breaking the vanilla feel.
These modpacks are intended as the recommended client setup for Mainstay SMP, but they can also be used as a clean base for your own custom modpack.
🧩 Core Philosophy
- Client-side only
- Vanilla-friendly gameplay
- Full compatibility with server-side mods
- Performance first, visuals second, utility third
- No unnecessary or intrusive mechanics
The goal is simple:
see more, know more, play smoother — without changing how Minecraft works.
⚡ Performance & Stability
Both editions focus on stable, efficient gameplay:
- Sodium ecosystem (Sodium, Sodium Extra, Reeses Options)
- Lithium, FerriteCore, ImmediatelyFast
- Entity Culling, More Culling
- Dynamic FPS for background optimization
These mods ensure high FPS, reduced stutter, and low memory usage even on large servers.
🎨 Visual Improvements (Vanilla Style)
Visual upgrades are carefully selected to enhance immersion without altering Minecraft’s original look:
- Better Clouds, Continuity
- Entity Texture & Model Features
- Skin Layers 3D, Capes, Wavey Capes
- Iris (shader support, optional)
- Ambient-friendly particle and lighting tweaks
🗺️ Exploration & Navigation
Designed to fully support server-side features:
- Xaero’s Minimap & World Map (+ XaeroPlus)
- Waypoints and zoom tools
- Voxy for extended world rendering (server-friendly)
🔊 Audio & Social Interaction
Immersion and communication are key on SMP servers:
- Simple Voice Chat + Voice Messages
- Presence Footsteps (Full Edition)
- Drip Sounds (Full Edition)
- Clear positional and environmental audio
🧱 Utility & Quality of Life
Small changes that make a big difference:
- AppleSkin, Jade / WTHIT
- Quick Shulker, Peek, Shulker tooltips
- Better Stats, Status indicators
- Inventory, hotbar, and UI enhancements
- Litematica & Syncmatica (for supported servers)
Many mods unlock extra functionality when the server provides matching server-side mods.
🔀 Modular by Design
- Some mods are disabled by default
- Alternatives are included where relevant
- Users can switch mods depending on:
- Server rules
- Performance needs
- Personal preferences
This makes the modpack flexible and future-proof.
