Stack Compare explains why two similar-looking item stacks will not stack. Open your inventory or a chest, press G, then click the two items to inspect their differences.

Features

• Compare custom names, enchantments, durability, potion information and other item data.
• A compact vanilla-style gray panel shows item icons, names, counts and a clear verdict. Expand details only when needed.
• Works with currently open inventories and containers. Copy diagnostic results.
• Distinguishes compatible stacks, counts exceeding one stack, incompatible items and uncertain results.

Controls and requirements

Put the JAR in the client mods folder. Open an inventory or chest, press G, and left-click two items. Use Details, Copy and Reselect. Press Esc, right-click or press G again to exit. Rebind G in Minecraft controls if needed.

Supports 21 Forge release versions from Minecraft 1.20.1 through 26.3, with a separate JAR for each game version. Select the exact Minecraft version on the download page. Use Java 17 for 1.20.1–1.20.4, Java 21 for 1.20.6–1.21.11, and Java 25 for 26.x. Minecraft 1.20.5 and 1.21.2 have no official Forge release and are not listed as compatible. Client-side only; no additional mods are required and the server does not need this mod.

Read-only diagnostics: no item changes, forced stacking or repairs. Only already-synchronized visible slots are inspected. Custom third-party rules may produce uncertain results. Results are snapshots; reselect after items change.

物品堆叠诊断 Stack Compare

两组物品看起来一样，却叠不到一起？打开背包或箱子，按 G，依次点击两个物品，直接查看差异。

功能

• 比较名称标签、附魔、耐久、药水和其他物品数据。
• 原版灰色像素面板，图标、名称、数量和结论一眼看清，详细字段按需展开。
• 支持当前已打开的背包与容器，可复制诊断结果。
• 区分可以堆叠、总数超过一组上限、不能堆叠和无法确认。

操作与安装

把 JAR 放进客户端 mods 文件夹。打开背包或箱子，按 G 后依次左键选两个物品；点“详情”展开数据，“复制”导出结果，“重选”再次比较。Esc、右键或再次按 G 退出。可在控制设置改绑按键。

支持 Minecraft 1.20.1 至 26.3 的 21 个 Forge 正式版本。 每个游戏版本都有独立安装包，请在下载页选择自己的 Minecraft 版本。1.20.1–1.20.4 使用 Java 17；1.20.6–1.21.11 使用 Java 21；26.x 使用 Java 25。1.20.5、1.21.2 没有官方 Forge 发布包，未提供对应文件。仅客户端需要安装，无额外前置，服务器无需安装。

只读诊断，不修改物品，不强制合并或修复。只读取服务器已经同步的可见槽位；第三方自定义规则可能无法确认。结果是选择时的快照，物品变化后需重新选择。
