Managing item transfer timing across mixed hopper networks has always been one of Minecraft's quiet headaches — and that's exactly the problem Cooldown Coordinator Mod solves. This library mod gives developers a clean interface to coordinate item movement cooldowns between vanilla hoppers and modded item-transferring blocks, preventing the timing conflicts that plague complex automation setups. With over 58,000 downloads on Modrinth and active development since 2022, it has become a reliable behind-the-scenes dependency for several popular Fabric mods.
Key Features
- Heterogeneous hopper network support — Enables smooth coordination between vanilla hoppers and modded item-transferring blocks, so mixed networks behave predictably instead of fighting over transfer timing.
- Developer-friendly cooldown API — Provides a simple interface for mod authors to implement and a method to call when a cooldown should be triggered, keeping the integration lightweight and straightforward.
- Broad mod loader compatibility — Supports both Fabric and Quilt, giving mod developers flexibility in which ecosystem they target.
- Open-source under Apache 2.0 — The full source is available on GitHub, allowing developers to inspect, contribute to, or fork the project as needed.

FAQ
Do I need Cooldown Coordinator as a regular player?
You typically won't install it on its own. Cooldown Coordinator is a library mod — you'll only need it if another mod you're using lists it as a required dependency. In that case, just drop it into your mods folder alongside the mod that needs it.
Does Cooldown Coordinator work with Quilt?
Yes, the mod supports both Fabric and Quilt mod loaders. You'll still need Fabric API (or the Quilt equivalent, Quilted Fabric API) installed as a dependency.
Is Cooldown Coordinator still being updated?
Yes, the mod is actively maintained. The most recent update was in November 2025, which added compatibility with Minecraft snapshot 25w46a and updated internal dependencies.
