Looks quite nice. The online editor with color coding looks sleek. I suppose that they are using a PEG-parser to parse the grammar in the online editor. Can you also specify color coding for your grammar? This is a parser generator. In the online editor, even with the example grammar, you can see that there is some delay when you change the grammar in what is being parsed. I wrote an interactive back-tracking parser with caching that does not show less delay with a bit larger grammar. Search for 'IParse Studio'.
