Quick answer
Which Elixir release matches 25w34b?
Elixir 3.9.0-alpha.25w34b for 1.21.9 is a complete pack release for 25w34b with Fabric 0.17.0. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 22 mods in this pack file.
Pack setup
How should I set up Elixir for players and a server?
Use Elixir 3.9.0-alpha.25w34b for 1.21.9 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 Elixir?
Elixir 3.9.0-alpha.25w34b for 1.21.9 on 25w34b. The pack contents and setup notes below stay tied to that release.
The selected pack release is Elixir 3.9.0-alpha.25w34b for 1.21.9. That file is for Minecraft 25w34b with Fabric 0.17.0. It contains 22 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.
About this project
What kind of pack is Elixir?

👋 Welcome to Elixir
What is Elixir?
Elixir is a Fabric modpack dedicated to purely performance and resource pack compatibility. It makes for a great modpack template for new modpacks as it remains up-to-date and allows the user to customize and add on their own mods that they want to the pack without it coming pre-packaged with additional bloat. And it's great for users who don't often use mods because it should act very similarly to vanilla but with much better performance.
Performance & Compatibility
Elixir's optimizations allow for far better FPS, memory usage, chunk loading, resource pack compatibility, modpack compatibility, and more! In general, the specific optimization mods implemented in this pack more often than not lead to better results and compatibility than OptiFine and some other alternatives. As for compatibility, for example, Elixir offers support for resourcepacks such as Fresh Animations, Dramatic Skys, and Redstone Tweaks. NOTE: Support is always dependent on if the mod dependencies are updated to the latest Minecraft versions.
Quality of Life
Quality of life features are secondary to performance, compatibility, and the vanilla feel. Any additions to Elixir are carefully curated to match this criteria. A zoom mod or a mod adding a targeted entity's health to the F3 screen, for example, are simple features that do not distract from the vanilla game, and due to their simplicity, they present practically zero performance or compatibility issues including with other existing mods.
Vanilla Parity
One issue that plagues many other existing performance modpacks is a lack of vanilla parity due to a few included mods or config settings that in some cases affects gameplay in a way that differs from vanilla. This includes parts of the game such as world generation, rng, mob spawning, and entity pathfinding, which can negatively impact redstone contraptions, farms, and lead to conflicts with a larger set of mods that players may also want to use. As a result of its importance, I made it my goal to create a modpack that maintains vanilla parity in gameplay.
Shaders
Using Iris's shader implementation, Elixir enables the usage of both old and new shaderpacks while also benefitting from some very helpful performance mods!
