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. To use it, type your text into the input box in the middle of the screen, pick a preview format from the buttons at the top (chat, lore, hologram, or server list), and read the rendered result in the output area below the input. No installation is described on the site — it runs as a web page.

What you need before starting

• A browser and a working connection to the page. The site shows a "Your connection with the server has been lost, please reload the page" message when the connection drops, so a stable connection matters.
• The text you want to format, plus any MiniMessage tags you plan to use. The tool generates and edits MiniMessage strings; it does not replace knowing the format itself.
• A target context in mind. The same string can look different depending on whether it is shown in chat, lore, a hologram, or a server list entry, which is why the format selector exists.

Step-by-step: create and preview text

1. Enter your text. Click into the input box in the middle of the screen and type or paste your content. This is the MiniMessage source that the tool will render.
2. Choose a preview format. Use the buttons at the top to switch between Chat (Closed), Chat (Open), Lore, Hologram, and Server List. The selected format changes how the output is drawn, so check your text in the context where it will actually appear.
3. Apply formatting. Use the buttons above the input to make text bold, italic, or underlined. You can also add clickable URLs, clickable commands, and hover text. Each of these inserts the corresponding MiniMessage markup into your string.
4. Check the output. The rendered preview appears below the input. If something looks wrong, edit the input or the markup and the output updates.
5. Apply color if needed. The interface includes an "Apply color" control alongside the input, useful when you want to set coloring without hand-writing the tag.

A practical example: if you are writing a server list entry, switch to the Server List format first, then add your description text and formatting. What reads well in chat may wrap or truncate differently in the server list slot, and previewing in the right format catches that before you paste the string into your plugin config.

Sharing, exporting, and in-game preview

Once the text looks right, the top of the screen offers several ways to move it out of the tool:

The in-game option is the most reliable final check, because it renders your text through the actual game client rather than a browser approximation. The site notes that this is not official Minecraft software, so treat the preview server as a testing aid.

Common snags

• Output stops updating or shows a connection error. Reload the page; the tool depends on a live server connection, and unsaved work in the input may be lost.
• A shared link no longer works. It was probably a short link past the 6-month expiry. Regenerate and use the full link this time.
• Text looks fine in one format but wrong in another. Re-check with the format selector — chat, lore, holograms, and server lists each have their own layout constraints.
• You need the raw string, not a picture. Use Export to JSON or copy the MiniMessage from the input; the preview alone is not something you can paste into a config.

When this tool is the right choice

Use MiniMessage Viewer when you want to iterate on formatting visually before committing a string to a plugin or mod, especially for multi-context text like a server list description that also appears elsewhere. If you already know MiniMessage syntax well and only need a syntax reference, the official MiniMessage documentation linked from the site is the better stop. The source code is available on GitHub if you want to inspect or self-host the interface.

MiniMessage is a compact, human-readable text format from the Adventure library for representing rich text. In Minecraft, it is used by plugins and mods to format text in chat messages, item lore, holograms, and server list entries. You write tags inline with your text instead of building complex JSON, and the Adventure library renders the result. For deeper reference, the official MiniMessage documentation is the place to look; the MiniMessage Viewer (also called Adventure WebUI) is a browser-based editor for writing and previewing it.

How MiniMessage fits into Minecraft text

Minecraft servers and plugins need styled text: colors, bold or italic spans, clickable links, hover tooltips. MiniMessage expresses all of that in a single readable string, which makes it easier to write by hand and easier to review in config files than nested JSON components.

The format is tied to the Adventure library, so anywhere a plugin or mod uses Adventure for text, MiniMessage strings are typically accepted. That covers the four common display contexts:

Where you will encounter it

• Plugin and mod configuration files — message templates, prefixes, menu titles, and item descriptions are often stored as MiniMessage strings.
• In-game previews — the Viewer can copy a Minecraft server address to your clipboard so you can add it to your server list and see the formatted text in-game.
• Sharing and reuse — the Viewer can produce a short link or full link to your text, and export it to JSON for pasting into a plugin or mod. Short links expire after 6 months, so keep the full link if you need it longer.

Why use a viewer instead of writing blind

MiniMessage is readable, but mistakes in tag syntax or nesting are easy to miss until the text appears in-game. A viewer gives you immediate feedback: you enter text in the input box, choose the preview format (chat, lore, hologram, or server list) with the buttons at the top, and the output appears below the input. Formatting buttons above the input handle bold, italic, underline, clickable URLs, commands, and hover text, so you do not have to remember every tag by hand.

For example, if you are writing a server list MOTD with a colored title and a hover tooltip, you can build it in the Viewer, switch to the server list preview, and confirm the layout before copying the string into your config.

Getting started

1. Open the MiniMessage Viewer in your browser.
2. Type or paste your text into the input box in the middle of the screen.
3. Use the top buttons to pick the preview format and apply formatting.
4. Check the output below the input.
5. Share via short or full link, or click "Export to JSON" to get a JSON representation for your plugin or mod.

If you want an in-game check, use the "Try in-game" button to copy a server address and add it to your Minecraft server list. Note that the Viewer is not official Minecraft software.

To share or reuse text you build in MiniMessage Viewer (Adventure WebUI), use the buttons at the top of the screen: Share short link or Share full link to send someone a URL, Export to JSON to get a JSON representation you can paste into a plugin or mod, or Try in-game to copy a Minecraft server IP that gives you an in-game preview. Short links expire after 6 months, so keep the full link if you need long-term access.

Before you start

• You have text in the input box in the middle of the screen. The output preview appears below it.
• You have selected the preview format you care about (chat, lore, hologram, or server list) using the buttons at the top, so what you share matches what you tested.
• If you plan to share a link, decide up front whether you need it to last longer than 6 months.

Share a link

1. Click Share short link or Share full link in the top bar.
2. Copy the generated URL.
3. Send it to whoever needs to see or continue editing the text.

Expected result: the recipient opens the link and sees your MiniMessage input and its preview.

Key catch: short links expire after 6 months. If the text is documentation, a template, or anything you'll come back to, use the full link or save the MiniMessage string itself somewhere durable.

Export to JSON

1. Click Export to JSON at the top of the screen.
2. Copy the generated JSON.
3. Paste it into your plugin or mod where the JSON representation is accepted.

Expected result: you get a JSON version of your MiniMessage text that you can move into your project without retyping formatting.

Use this when your workflow consumes JSON rather than a MiniMessage string. If your plugin expects a MiniMessage string instead, copy the input text directly rather than the JSON export.

Preview in-game

1. Click Try in-game at the top of the screen.
2. The button copies a Minecraft server IP to your clipboard.
3. Add that IP to your server list in Minecraft and join to see the text rendered in-game.

Expected result: you see your formatting as players would, which catches differences the browser preview may not show.

Note that the page identifies itself as not official Minecraft software, so treat the in-game preview as a testing aid rather than a production server.

Choosing between the three

Common snags

• Link stopped working: the short link hit its 6-month expiry. Recreate it or use the full link next time.
• "Your connection with the server has been lost, please reload the page": reload the page and re-enter or re-open your text before exporting.
• JSON doesn't work in your plugin: check whether the plugin expects a MiniMessage string or a JSON component; the export only helps in the latter case.
• In-game preview looks different from the browser: that's the point of the in-game check — adjust formatting until both match.

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.

The MiniMessage Viewer (also called Adventure WebUI) is open source: its code is hosted on GitHub, and the MiniMessage format itself is documented on the official Adventure documentation site. Use the GitHub repository if you want to inspect how the viewer works, report an issue, or contribute; use the Adventure docs if you need the authoritative reference for MiniMessage syntax and behavior.

Source code: Adventure WebUI on GitHub

The MiniMessage Viewer page states that the source code for Adventure WebUI, also known as MiniMessage Viewer, can be found on GitHub. That repository is the place to go for:

• Verifying how a specific feature (preview modes, sharing, JSON export) is implemented
• Checking behavior when the live site and your expectations differ
• Filing bug reports or contributing changes

The site itself does not print the repository URL in the text provided, so search GitHub for "Adventure WebUI" or "MiniMessage Viewer" rather than guessing a path.

Format documentation: official Adventure docs

The viewer's FAQ points to the official documentation for learning MiniMessage itself. This is the reference to use for tag syntax, color and formatting tags, and how MiniMessage strings are structured — the viewer is an editing and preview tool, not the specification. If a tag behaves unexpectedly in the preview, check the docs first, then the GitHub source.

Which resource to use

Practical notes

• The viewer's FAQ describes the workflow: enter text in the middle input box, pick a preview format (chat, lore, hologram, server list) with the top buttons, and see output below. Formatting buttons add bold, italic, underline, clickable URLs, commands, and hover text.
• Sharing has a time limit worth knowing before you rely on links: short links expire after 6 months, so save the full link if you need it longer. "Export to JSON" produces a JSON representation for pasting 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. The page notes this is not official Minecraft software.
• The page also shows a "Your connection with the server has been lost, please reload the page" message as part of its interface text; if you see it while using the tool, reload before assuming a bug in your MiniMessage string.
