Sourcegraph vs GitHub code search

SGitHub code search lets users search and navigate organization and open source code and supports searching code across GitHub using regular expressions, boolean operations, specialized qualifiers, and symbol search.
‍

GitHub code search is available to all users but comes with limitations. Not all code is indexed, search results are restricted to 100 results, and it does not support multi-line searching. It does not offer comprehensive search across branches, nor offers granular search parameters like case-sensitive search. GitHub code search is unable to make and track large-scale changes across repositories and code hosts or transform code into a queryable database to create custom, visual dashboards to track migrations, vulnerabilities, code health, and other metrics.
‍

TL;DR: GitHub code search is a good choice for individuals or small teams operating with a small codebase looking to find code, issues, or pull requests with simple search queries. Sourcegraph Code Search is a better option for organizations with a large number of repositories or a large and complex monorepo, and are looking for more sophisticated and accurate ways to search and navigate all of their code. Sourcegraph Code Search also offers enterprises a way to make large-scale changes and track insights across their codebase at scale. For example, you can read how Nutanix used Sourcegraph Code Search to identify and fix every instance of the Log4j vulnerability.
