When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited integrations with non-JavaScript environments

   Pen's primary language is JavaScript, which can limit its usability in projects that do not use JavaScript.

2. 02

   Performance issues with large Markdown files

   Live preview can become sluggish or unresponsive when working with extensive Markdown documents due to real-time rendering overhead.

3. 03

   Small community and limited third-party support

   As an open-source tool, Pen has a relatively small user base which translates into fewer contributions, plugins, and community-driven improvements.

What it does well

• Live preview of Markdown changes in real-time
