The Innerwiki Plugin enables TiddlyWiki to embed a modified copy of itself (an "innerwiki"). The primary motivation is to be able to produce screenshot illustrations that are automatically up-to-date with the appearance of TiddlyWiki as it changes over time, or to produce the same screenshot in different languages.

In the browser, innerwikis are displayed as an embedded iframe. Under Node.js Google's Puppeteer is used to load the innerwikis as off-screen web pages and then snapshot them as a PNG image.
