OpenGrok (https://github.com/oracle/opengrok) is a wonderful tool to search a codebase. It runs on-prem and handles lots of popular programming languages.

[4] is not really a usable 'product'. Livegrep (https://github.com/livegrep/livegrep) was inspired by it and is very usable. [3] used to be a Google open source project as well, but it fell out of maintenance, and Sourcegraph took it over. It powers most of the basic regex/literal search in Sourcegraph. Mozilla's code is searchable in Searchfox (https://searchfox.org/) which uses the indexer from Livegrep, combined with their own Git indexer and language-specific cross reference databases. OpenGrok (https://github.com/oracle/opengrok) is also rather well known, but I have found it to have a slightly worse UI than alternatives.

OpenGrok, while an older tool, is web based and a very nice way to explore large codebases; and it is multi language as well [2] To get you started, here are public instance with source code for Illumos [3] and multiple BSDs [4]. Used to have a Linux one but cannot find atm. [1] https://oracle.github.io/opengrok/ [2] https://github.com/oracle/opengrok/wiki/Supported-Languages-...

If you want to do code search on your private git, mercurial, svn, cvs and other repositories try a fully open source opengrok (https://github.com/oracle/opengrok). It’s easy to self install and use, with good documentation with added bonus very fast.

Sourcegraph only support git repository so it's not very useful for enterprise with mercurial, svn or other distributed version control systems. There is another open source application for code search opengrok [1] (it's completely open source unlike sourcegraph and supports multiple version controls beside git). Take a look. It's easy to install and operate on bare metal, cloud and containers, instead of convoluted sourcegraph way of kubernetes or docker. [1] https://github.com/oracle/opengrok

just installed opengrok and tried it and it's very good. linux kernel uses LXR, might be useful too. here is a comparison chart: https://github.com/OpenGrok/OpenGrok/wiki/Comparison-with-Si...

I never got around to really testing it, but still remember when OpenGrok was announced, way back when - apparently it's still active. I've been wondering if it would make a good front-end/source-browser component for a trac[t]-like product (with something else for vcs and bug tracking etc): https://github.com/OpenGrok/OpenGrok There's also a list of similar tools at Gnu.org: https://www.gnu.org/software/global/links.html Thought it might be of interest for others looking at "source browsing" tools.

I have written about it all here (I maintain searchcode.com ) http://www.boyter.org/category/searchcode/ specifically http://www.boyter.org/2013/02/why-code-search-is-difficult/ is of note. If you want to see implementations I suggest looking at https://github.com/OpenGrok/OpenGrok https://github.com/ggreer/the_silver_searcher https://github.com/google/codesearch and my own https://github.com/boyter/searchcode-server

Thanks for mentioning Super User's BSD Cross Reference (bxr.su)! Apparently there are many more OpenGrok installations nowadays than it used to be 5 years ago. https://github.com/OpenGrok/OpenGrok/wiki/OpenGrok-installat... EDIT: Not all of them are working, though.

And partially related to the task of understanding/navigating a code-base: https://github.com/OpenGrok/OpenGrok

For me, the most useful information was the "Comparison with Similar Tools" table (in the OpenGrok project wiki), which was linked-to from the GNU GLOBAL page: https://github.com/OpenGrok/OpenGrok/wiki/Comparison-with-Si... As a Vim user, the comparisons to Ctags and cscope were informative. And the list of supported languages is impressive! Awk, Dos batch, COBOL, C, C++, C#, Erlang, Fortran, Java, JavaScript, Lisp, Lua, Pascal, Perl, PHP, Python, Ruby, Matlab, OCaml, Scheme, Tcl, TeX, Verilog, Vhdl and Vim.
