From my experience with OpenGrok, I found it excels at providing fast and reliable source code search and cross-reference capabilities, especially for large and complex codebases. Its open source nature and support for multiple programming languages make it a versatile tool for development teams and open source projects. However, setting it up requires some technical knowledge and server resources, and its interface feels utilitarian rather than modern. Overall, if you need a robust, self-hosted code search engine to improve code navigation and understanding, OpenGrok is a solid choice.
