What is MiniMessage Viewer (Adventure WebUI)?

Updated

MiniMessage Viewer (also called Adventure WebUI) is a browser-based editor for MiniMessage, the rich-text format used by the Adventure library in Minecraft plugins and mods. You type MiniMessage into an input box, preview it in formats such as chat, lore, holograms, and server list entries, and then share or export the result. It is not official Minecraft software, so treat it as a third-party helper for authoring and checking text rather than a game feature.

What you can do with it

The page is organized around a single input box with preview and output areas. According to the site's FAQ, the main actions are:

  • Preview in context — buttons at the top switch the preview between chat, lore, hologram, and server list formats, so you can see how the same string reads in each place it might appear.
  • Format text with buttons — bold, italic, underline, clickable URLs, commands, and hover text can be added without memorizing every tag.
  • Apply color — an "Apply color" control sits next to the input.
  • Share a link — short links or full links to your text; short links expire after 6 months, so save the full link if you need it longer.
  • Export to JSON — produces a JSON representation you can copy into a plugin or mod.
  • Try in-game — copies a Minecraft server IP to your clipboard that you add to your server list for an in-game preview.

When it fits your task

Use it when you are writing MiniMessage by hand and want fast visual feedback, or when you need to check that one string works across chat, lore, holograms, and server list entries before pasting it into a plugin config. It is less useful if you already have a working in-game preview loop or need to edit many strings programmatically — the JSON export helps there, but the tool is built around one string at a time.

The site also notes that the connection can drop ("Your connection with the server has been lost, please reload the page"), so keep a copy of longer strings outside the browser tab.

Practical workflow

  1. Enter your MiniMessage text in the middle input box.
  2. Pick the preview format at the top (chat, lore, hologram, server list).
  3. Use the formatting buttons for bold, italic, underline, links, commands, and hover text; use "Apply color" for colors.
  4. Check the output below the input.
  5. Share a short or full link, export to JSON, or use "Try in-game" to preview on a Minecraft server.

Things to know before relying on it

  • MiniMessage itself is documented by the Adventure project; the Viewer is a convenience layer, not the specification.
  • Short share links expire after 6 months — the full link is the durable option.
  • The source code is on GitHub if you want to verify behavior or self-host.
  • It is not official Minecraft software, so previews are a close guide, not a guarantee of exactly how a specific plugin will render your text.
