Sourcegraph is a fast, open-source, fully-featured code search and navigation engine. It provides Fast global code search with a hybrid backend that combines a trigram index with in-memory streaming, Code intelligence for many languages via the Language Server Protocol.

Comby is language-aware and understands basic syntax of code, strings, and comment syntax in many languages.</p>

It doesn&rsquo;t implement a full parser for every language, but rather a more general grammar so that it works on a lot of languages (just like regular expressions work on the text of every language).</p>

Comby - A code rewrite tool for structural search and replace that supports every language

A code-searching tool similar to ack, but faster. It ignores file patterns from your .gitignore and .hgignore. If there are files in your source repo you don't want to search, just add their patterns to a .ignore file. (*cough* *.min.js *cough*)

The Silver Searcher - A code-searching tool similar to ack, but faster.

This is a fast text search engine, intended for use with source code. (Pronunciation: roughly as you would pronounce "zooked" in English)


Zoekt - Fast trigram based code search  

searchcode server is a powerful code search engine with a sleek web user interface. searchcode server works in tandem with your source control system, indexing thousands of repositories and files allowing you and your developers to quickly find and reuse code across teams.
