MarkFoundry uses a separate Docker conversion service for heavy document conversions. This service runs Pandoc outside the Vercel app to support PDF and DOCX export with better reliability.
Technical note
MarkFoundry is available at https://markfoundry.app/ as a browser app and installable PWA. The editor runs as a web application on your device. Heavy PDF and DOCX conversions are designed to run through a separate Docker conversion service powered by Pandoc.
