We present eXLEpse, an easy-to-use editor for creating computational grammars based on the Lexical-Functional Grammar (LFG) formalism (Dalrymple, 2001). The editor is implemented as a plugin for the open-source program development platform Eclipse. eXLEpse provides functionality for editing computational LFG grammars and an interface to the XLE grammar development platform (Crouch et al., 2011). The editor can replace Emacs as an editor and provides a graphically enriched user interface as an alternative to the shell-based interface of the XLE platform. It is available free of charge on the internet.
