## What it is
remark is a plugin-powered markdown processor built on the unified ecosystem that parses markdown into an AST (mdast) and transforms it. It is 100% CommonMark compliant, supports GFM and MDX via plugins, and runs on the server, client, and CLIs.

## Use cases
- convert markdown to html in node
- lint and format markdown files
- parse markdown into an ast for custom transformations
- add gfm or mdx support to a markdown pipeline
- build a markdown-based static site or docs pipeline
- check markdown style on the cli

## When to choose
- you need programmatic, AST-level manipulation of markdown
- you want a composable plugin ecosystem with 150+ plugins
- you need strict CommonMark compliance with optional GFM/MDX
- you want one pipeline for markdown linting, transformation, and HTML output

## When to avoid
- you just need a quick one-off markdown-to-HTML string conversion with no plugins
- you need a WYSIWYG markdown editor UI
- you work in a non-JavaScript language without unified bindings

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, plugin-system, formatter, linter
- domain: web-development, developer-tools, documentation, parsers
- platform: browser, cli, cross-platform
- tags: unified, mdast, commonmark, gfm, mdx, ast, ecosystem, nodejs, deno
