Code Fundi vs OpenGrok

Code Fundi turns indexed repositories into searchable maps of a codebase for AI agents, teams, and applications. Search combines semantic search with documentation-aware and code grep; research adds AI synthesis grounded in repository search results. Its blast-radius analysis maps dependents, data flows, entry points, and call edges, and requires a DEV plan or higher. Users can access it through a web app, MCP server, HTTP API, or extensions for VS Code and Cursor; the maker also lists Windsurf support. The versioned API covers search, research, indexing, blast-radius analysis, Markdown blueprints, file documentation, history, and account utilities. Private repositories require a linked GitHub account with access. The maker says proprietary code is not used to train public models and describes its approach as zero-data retention. Plans set credit allowances, private repository caps, usage-log retention, and Markdown detail levels; research and chat can add model usage on top of base credit costs. Free includes 500 credits and email support; paid plans are Dev at $21 a month, Startup at $62 a month, and Pro at $210 a month.

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.
