Firmament is a utility mod that adds Hypixel SkyBlock quality-of-life tools, recipe viewers, and inventory helpers for Minecraft Fabric.
Hypixel SkyBlock can get messy fast when you are trying to track items, check recipes, manage storage, and keep useful overlays in sight. Firmament brings those jobs together in one place, and its 1.25 million+ downloads suggest that a lot of players already rely on it for that exact reason.
Key Features of Firmament
- Item list and grouped SkyBlock items — Firmament gives you a catalog of SkyBlock items and also groups related items together, such as minions. That matters because SkyBlock inventories are easier to understand when related items are organized instead of scattered across unrelated menus.
- Crafting and forge recipe viewers — The mod includes separate viewers for crafting recipes and forge recipes, which makes it easier to check requirements before you commit resources. In practice, that saves time and reduces the friction of bouncing between menus or external references while you are building progress in SkyBlock.
- Chat image preview — Image previews in chat make shared references easier to read without guessing what someone meant. If your guild or party shares item images, this is the kind of feature that keeps chat usable instead of turning it into a wall of context you have to open elsewhere.
- Storage and crafting helpers — Firmament includes a storage overview and a crafting overlay that appears when you click the "Move Item" plus inside a crafting recipe. The storage side is not yet a fully interactive overlay, but even the current version helps you understand where things are and how to move them with less friction.
- Cursor and slot management — The cursor position saver and slot locking are the sort of tools you only miss after you lose them. They help preserve your place during repeated interactions and reduce accidental item movement, which is especially useful when you are dealing with menus, crafting, or anything that rewards precision.
- Visual helpers and HUD customization — Firmament supports custom texture packs by loading models from the firmskyblock: namespace before vanilla models, includes a fairy soul highlighter, and uses a HUD editor powered by Jarvis. That combination matters if you want the mod to fit your setup instead of forcing you to adapt to its defaults.
- Fishing and configuration tools — The fishing helper highlights fishing particles, and the mod also ships with a basic config GUI through
/firm config. The config interface is still described as a work in progress, but it gives you a practical starting point, and/jarvis optionsadds a searchable way to find settings faster.

Alternatives to Firmament
- Not Enough Updates — Firmament is inspired by NEU, so this is the most obvious comparison if you want the broader SkyBlock QOL reference point.
- DulkirMod — The author specifically recommends checking it out, which makes it a natural companion if you want more SkyBlock client-side utility.
- Jarvis — Firmament's HUD editor is powered by Jarvis, so it is the relevant name to know if you care about the UI and overlay side of the setup.

Frequently Asked Questions
Is Firmament only for Fabric?
Yes — the data lists Fabric Mod Loader as the required loader and the available downloads are Fabric builds. That makes it a straightforward choice if your client is already on Fabric, but not a candidate for other loaders based on this data.
Which Minecraft versions are supported?
It supports Minecraft 1.21.11, 1.21.10, 1.21.8, 1.21.7, 1.21.5, 1.21.4, 1.21.3, 1.21.1, 1.21, and 1.20 through 1.20.6. If you are on one of those versions, there is a matching Fabric download in the provided data.
Does it include recipe viewing?
Yes — it includes viewers for both crafting recipes and forge recipes. That matters because it reduces tabbing out or guessing when you are trying to build or combine SkyBlock items efficiently.
Is the storage overview fully interactive?
No — the data says it is only a storage overview for now, not a full overlay that lets you interact with every page. The author also notes that more interaction is planned, so treat the current version as useful but incomplete.
Does Firmament have a fishing helper?
Yes — it includes a fishing helper for fishing particles. The author also notes a sneaking-related positioning issue on 1.20, so that specific helper has a known limitation in some situations.
Can I configure it in game?
Yes — there is a basic config GUI through /firm config, and you can also search config options with /jarvis options. The config experience is described as still needing improvement, but it covers the basics.
