OpenGrok vs searchcode

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.

searchcode provides code-intelligence dossiers for public GitHub repositories, covering languages, complexity, technology stacks, code quality, and secrets. Its MCP server exposes six tools for AI assistants, and each tool is also available as JSON over HTTP through the REST API. Analysis reports language breakdowns, complexity metrics, detected technologies, quality findings, and credentials such as API keys, tokens, and private keys with file, line, and confidence details. Search supports full text, boolean logic, regular expressions, and structural filters for declarations, usages, strings, and comments. File retrieval can return complete files, line ranges, or named symbols with nearby declarations; batch retrieval handles up to 10 files. The free beta plan covers public GitHub repositories without signup, an API key, or installation. Enterprise deployment runs on customer infrastructure as a Docker image with a Kubernetes Helm chart. Private repositories can authenticate with SSH keys or HTTPS tokens.
