babelmark3 (via) I found this tool today while investigating an bug in Datasette’s datasette-render-markdown plugin: it lets you run a fragment of Markdown through dozens of different Markdown libraries across multiple different languages and compare the results. Under the hood it works with a registry of API URL endpoints for different implementations, most of which are encrypted in the configuration file on GitHub because they are only intended to be used by this comparison tool.
