OpenGrok vs sqry

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.

sqry is an open-source code analysis tool from Verivus Pty Ltd. It parses source code into an abstract syntax tree and a graph of symbols and relationships, then answers structural questions such as which functions call another. Its documented queries cover callers, callees, implementations, dependency cycles and unused symbols. The project lists 37 language plugins: 28 support full relation tracking, while nine extract symbols and imports. Users build an index before querying; it persists so later queries can load the cached graph snapshot. sqry runs locally on Linux, macOS and Windows, under the MIT license. Its maker says source code stays on the machine and the tool has no telemetry. It offers an MCP server for AI assistants, with 39 tools in standalone mode and a curated subset of 16 in daemon mode. An LSP server works with VS Code, Neovim, Helix and LSP 3.17 clients. Installers are listed for the three desktop platforms, as is cargo installation. Windows executables require bundled MinGW runtime DLLs; the release ZIP includes them.
