Code Search vs Semantic Designs Source Code Search Engine

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.

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.
