How to format messages on Fluxer

Markdown in Fluxer: bold, lists, code blocks, tables, spoilers, timestamps, alerts and more, with what to type for each one.

Last updated on November 1, 2026

You format a Fluxer message by typing Markdown around your text, and the same syntax works in the web app, the desktop app and the iOS and Android apps.

Does Fluxer support Markdown?

Yes. Type these around your text to format it.

Type this To get
**bold** bold
*italic* or _italic_ italic
***bold italic*** bold italic
__underline__ underlined text
~~strikethrough~~ strikethrough
`code` code
[link text](https://fluxer.com) link text
\*not italic\* *not italic*

A backslash before a symbol shows the symbol itself. To hide text as a spoiler, put two vertical bars on each side of it, and people click the spoiler to reveal it.

How do I add headings, lists and quotes?

Start a line with one of these.

Start a line with To get
# , ## , ### or #### a heading, from largest to smallest
-# small, dimmed text
- or * a bulleted list
1. a numbered list
> a quote of that line
>>> a quote of that line and every line after it

Put two spaces before - to nest a list item under the item above it in the list. Each of these needs a space after the symbols, so #hashtag stays plain text.

How do I write a code block?

Put three backticks on the line before and the line after your code. Add a language after the first three backticks, such as js, py or rust, and the app colors the code for that language. With ansi, the app shows terminal color codes as colors.

```py
print("Hello")
```

Can I make a table?

Yes. Separate the columns with vertical bars and put a line of dashes under the header row. Tables show in messages, threads and forum posts in every Fluxer app.

Does Fluxer render LaTeX math?

Yes. Code blocks marked latex, tex or katex show as math, and a math block has a size limit. Math between dollar signs in a line of text isn't supported.

Where doesn't formatting work?

Messages in channels, threads, forum posts, DMs and group DMs support everything on this page. The "About me" text on a profile supports text formatting, links, lists and quotes, but it doesn't support headings, code blocks, small text, tables or alerts.
