This article provides a basic feature comparison for several lightweight markup languages. See list of lightweight markup languages for relevant links.

Comparison of Syntax

Text/font-face formatting

Comparing text formatting syntax
Language	Bold	Italic	Monospace (teletype)	Notes
Almost Free Text	`_bold text_`	`''italic text''`	`\|monospace text\|`	Formatting will not occur across line breaks unless the first formatting character is the first character on the line.
BBCode	`[b]bold text[/b]`	`[i]italic text[/i]`	`[code]monospace text[/code]`	Formatting works across line breaks.
Markdown	`bold text` or `__bold text__`	`italic text` or `_italic text_`	`Non-monospace text` `monospace text` `more monospace text` Inline `monospaced` text.	Markdown doesn't use bold and italic tags, but rather `em` (typically italic) and `strong` (typically bold) tags. Monospace text is created by indenting that line 4 spaces or one tab character, or enclosing text in backticks: `monospaces`.
o7aCode	`'''bold text'''`	`''italic text''`	`°°°` `monospace text` `monospace text` `°°°`	o7aCode uses `em` (typically italic) and `strong` (typically bold) tags. All attributes of all markups can be filled in. Monospace text can be colored up by GeSHi.
POD	`B<bold text>`	`I<italic text>`	`C<monospace text>`	Indented text is also shown as monospaced code.
reStructuredText	`bold text`	`italic text`	``monospace text``
Textile	`bold text` or `bold text`	`_italic text_` or `__italic text__`	`@monospace text@`	Textile uses `em` (typically italic) and `strong` (typically bold) tags on single symbols, and `i` and `b` tags on double symbols.
Texy!	`bold text`	`italic text` or `//italic text//`	`monospace text`	Texy uses by default `em` (typically italic) and `strong` (typically bold) tags. It is possible to configure library to use another tags.
txt2tags	`bold text`	`//italic text//`	``monospace text``
MediaWiki	`'''bold text'''`	`''italic text''`	`<code>monospace text</code>`

Section headers

Comparing section header formatting
Language	Format	Notes
Almost Free Text	`* Level 1 Header` `** Level 2 Header`	Up to 4 levels
BBCode		Does not support section headers
Markdown	`# Level 1 Header` `## Level 2 Header` or `Level 1 Header` `==============` `Level 2 Header` `--------------`	You can optionally "close" the #-style headers with an equal number of #'s. The #-style headers support up to 6 levels. The = and - style headers support only the two shown.
o7aCode	`= Level 3 Header =` `== Level 4 Header ==`	The title first level can be set (by default : 3).
POD	`=head1 Level 1 heading` `=head2 Level 2 heading`
reStructuredText	`Chapter 1 Title` `===============` `Section 1.1 Title` `-----------------` `Subsection 1.1.1 Title` `~~~~~~~~~~~~~~~~~~~~~~` `Section 1.2 Title` `-----------------` `Chapter 2 Title` `===============`	Any of the following characters can be used as the "underline": = - ` : ' " ~ ^ _ * + # < >. The same character must be used for the same indentation level and may not be used for a new indentation level.
Textile	`h1. Level 1 Header` `h2. Level 2 Header`	Up to 6 levels
Texy!	`### Level 1 Header` `## Level 2 Header` or `Level 1 Header` `==============` `Level 2 Header` `--------------`	You can optionally "close" the #-style headers with an equal number of #'s. The #-style headers support up to 6 levels. The underlined style headers support four levels (### *** === ----). Real levels are calculated dynamically.
txt2tags	`= Level 1 Header =` `== Level 2 Header ==` `=== Level 3 Header ===`	Using `+` characters instead of `=` characters creates numbered headers (the default being unnumbered).
MediaWiki	`== Level 2 Header ==` `=== Level 3 Header ===`	= is available for level 1 header, but its use is discouraged in Wikipedia (reserved for page title). More = are possible, up to 6.

Link Syntax

Comparing link syntax
Language	Syntax	Notes
Almost Free Text	`[Link text (http://www.example.com)]`	Also has support for targeting references within the same text, not just URLs.
BBCode	`[url]http://www.example.com[/url]` `[url=http://www.example.com]Link text[/url]`	Some BBCode implementations can auto-parse URLs as well and convert them to `a` elements.
Markdown	`[Link text](http://www.example.com "optional title attribute")` or `[Link text][id]` and elsewhere `[id]: http://www.example.com "optional title attribute"`	Allows for an optional `title` attribute.
o7aCode	`[http://o7aCode.net/ :: official website of o7aCode :: en]o7aCode[/]` `[http://o7aCode.net/]o7aCode[/]` `[]http://o7aCode.net/[/]` `[http://o7aCode.net/ ;; id = id_for_the_link :: official website]o7aCode[/]` `[wp]Lightweight markup language[/]` ...	All attributes can be filled in (href, title, lang ...). The last example allows to make a link to a wikipedia article.
POD	`L</Internal Link>` `L<Perl::Module::Link>` `L<http://example.com/external_link>`	The core POD standard does not support external links with titles.
reStructuredText	`Link text <http://www.example.com/>`_	Can also be done in a non-embedded format which may be seen as more readable.
Textile	`"Link text (optional title attribute)":http://www.example.com` or `"Link text":alias` and elsewhere `[alias (optional title attribute)]http://www.example.com`	Allows for an optional `title` attribute.
Texy!	`"Link text .(optional title)[opt. class or ID]{opt. style}":http://www.example.com` or `"Link text":alias` and elsewhere `[alias]: http://www.example.com .(optional title)[opt. class or ID]{opt. style}`	Texy! modifiers allows for an optional `title` attribute, CSS classes, ID, inline style and HTML element attributes. Example: "Link .(title)[class#id]{color: blue;rel:nofollow}"
txt2tags	`[[Link text www.example.com]]`
MediaWiki	`[[Internal page]]` `[[Internal page\|Displayed text]]` `[http://www.example.com]` `[http://www.example.com External link]`	Wikitext can auto-parse URLs as well and convert them to `a` elements.

Comparison of language features

A lot of this was taken from http://bluebones.net/2005/02/humane-text-formats/

Comparing language features
Language	HTML export tool	HTML import tool	Tables	Link titles	class attribute	id attribute	Exportable formats	License
Almost Free Text	Yes	No	No	No	No	No	HTML, LaTeX, lout, DocBook, RTF	Clarified Artistic License
BBCode	No	No	No	No	No	No	?	?
Markdown	Yes	Yes	No	Yes	No	No	XHTML	BSD-style & GPL (both)
o7aCode	Yes	Yes	No	Yes	Yes	Yes	XHTML HTML ...	?
POD	?	?	?	?	?	?	?	?
reStructuredText	Yes	No	Yes	No	Yes	auto	Latex, XML, PseudoXML, HTML	Python License
Textile	Yes	No	Yes	Yes	Yes	Yes	XHTML	Textile License
Texy!	Yes	Yes	Yes	Yes	Yes	Yes	XHTML or HTML (always valid wellformed code)	GNU GPL v2 License
txt2tags	Yes	?	Yes	Yes	?	?	HTML, XHTML, SGML, LaTeX, Lout, UNIX man, MoinMoin, MagicPoint, PageMaker	GPL
MediaWiki	Yes	Yes	Yes	Yes	Yes	Yes	?	GNU GPL
