LXR Alternatives

LXR

LXR is a general purpose source code indexer and cross-referencer that provides web-based browsing of source code with links to the definition and usage of any identifier. It supports a wide choice of languages.
LXR used to stand for "Linux Cross-Referencer" but it has proved generic enough to be able to cross reference any project beyond the Linux kernel.

It is based on stock web technology (meaning its output is regular HTML), so the display client may be freely chosen from the available web browsers. It was a design choice not to use Java or any other client-side scripting language to minimise dependencies and system requirements.
