We use ANTLR on a daily basis to build several products.
We use it first of all to build parsers. If you need a parser to be built from scratch you can visit this page: parser services.
We also offer services specific to ANTLR:
- Reviews of existing ANTLR grammars
- Performance improvements for your ANTLR grammar
- Migration from ANTLR 2 or 3 to ANTLR 4
- Migration from Lex, Bison, Yacc, or similar tools to ANTLR 4
