Code Search vs OpenGrok

Code Search is a self-hosted platform for searching and changing code across repositories, with CLI support for batch work. Zoekt provides sub-second repository search; SCIP features support go-to-definition, find-references and symbol search. Teams can make replacements across multiple repositories and have the platform create branches and merge requests. A built-in MCP server connects assistants such as Claude and Cursor for code search, browsing and navigation. Supported code hosts include GitHub, GitHub Enterprise Server, GitLab, self-hosted GitLab, Gitea, and Bitbucket Cloud and Server. Deployment choices include Docker, source builds, Kubernetes and Helm. The maker says code and data stay on customer servers and the application sends no telemetry or usage data back. Community is free and includes unlimited users. Enterprise adds OIDC single sign-on, role-based repository permissions, audit logging and priority support; pricing is on request. Community support is available through GitHub Issues, and the project is licensed under Apache License 2.0.

OpenGrok is a Java source code search and cross-reference engine for searching and navigating source trees. It searches full text, definitions, symbols, paths and revision history, with subtree searches, wildcards and date-range filters. Its read-only web interface provides syntax-highlighted cross-references, file and directory history, and revision diffs. Supported revision control systems include Git, Mercurial, Subversion, CVS, Perforce, ClearCase, Bazaar, Monotone, Razor, RCS, SCCS, Teamware and AccuRev. Plugins can add support for programming languages or revision control systems. The web application provides a REST API under `/api/v1/` and a granular authorization framework; authentication is handled by the application server or a reverse proxy. Setup requires creating an index and deploying the web application. The guide lists Java 21 through 25, Universal Ctags and a servlet container such as Tomcat 10.x. OpenGrok is free and open source under the CDDL license, and is maintained by volunteers. Support and project requests go through discussions, mailing lists and GitHub Issues.
