'''Sourcegraph Inc.''' is a company developing code search and code intelligence tools that semantically index and analyze large codebases so that they can be searched across commercial, [[Open source|open-source]], local, and cloud-based [[Information repository|repositories]].<ref name="lwn">{{Cite web |last=Hoyt |first=Ben |date=2020-08-17 |title=Searching code with Sourcegraph |url=https://lwn.net/Articles/828748/ |access-date=2022-10-03 |website=LWN.net}}</ref>
The company has two products available: Cody and Code Search. Code Search was initially released in 2013 under the name Sourcegraph, but was rebranded to Code Search when the company unveiled Cody in 2023.

In 2023 Sourcegraph Inc. unveiled their new product Cody, and rebranded Sourcegraph to Code Search.
== Products ==
The company has two major products: Cody and Code Search.
=== Sourcegraph Cody ===
Cody is a free and open-source AI coding assistant that can help users write, fix, and maintain your code. It works by understanding an entire codebase and using that knowledge to provide context-aware assistance. including code generation, debugging, commenting, documentation, explaining, and answering questions regarding the code. Cody is available for Microsoft Visual Studio Code and most JetBrains IDEs.
=== Sourcegraph Code Search ===

Searches can be [[Literal (computer programming)|literal]], [[regular expression]], or structural. The structural search syntax is language-aware and handles nested expressions and multi-line statements better than regular expressions.<ref name="lwn" /> Sourcegraph's Code Search uses a variant of Google's [[PageRank]] algorithm to rank results by relevance.<ref>{{Cite web |last=Yegge |first=Steve |date=2022-11-08 |title=Rethinking search results ranking on Sourcegraph.com |url=https://about.sourcegraph.com/blog/new-search-ranking |website=Sourcegraph |access-date=2022-12-06}}</ref> Code Search can be used to search and analyze all of an organization's code.<ref name="at" /> During search indexing, the platform builds a global reference graph, that maps an entire codebase and enables functionality such as "go to definition".<ref>{{Cite web |last=Ramji |first=Sam |date=2022-12-22 |title=Google That Code: How Sourcegraph Simplifies Development |url=https://thenewstack.io/google-that-code-how-sourcegraph-simplifies-development/ |access-date=2023-02-20 |website=The New Stack}}</ref> Features include:
* Search: Code can be searched and navigated through the Sourcegraph web interface or through browser and [[Integrated development environment|IDE]] extensions and [[text editor]] plugins.<ref name="lwn" />
* Navigation: jumps to the definition of a variable or function, or find all references to it in a codebase.<ref name="lwn" />
