Code Fundi vs Semantic Designs Source Code Search Engine

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.

Semantic Designs Source Code Search Engine searches and inspects indexed code using language structure, so queries can target constructs and complex statements as well as text patterns. It supports regular expressions and numeric values or ranges, and searches can disregard whitespace, line breaks, and comments. The maker says it can search millions of lines across tens of thousands of source files. Results include surrounding code and highlighted matches; users can open source text or launch an editor on the matching file. The engine also calculates Cyclomatic and Halstead complexity metrics and counts source, code, comment, and blank lines. Listed scanners include ABAP, C, C++, COBOL, Java, JavaScript, Python, PHP, SQL dialects, and XML, with beta scanners and custom options. Files are collected, scanned, and indexed on a recurring schedule. Results can be produced in XML for other graphical interfaces. The free evaluation covers 10,000 lines and requires registration; its license ends 90 days after download. Pricing for a production license is available on request.
