| Integrations | The documentation lists use with Emacs, Vi, Less, Bash, web browsers, and Doxygen. | The installation guide documents MCP setup and a Zed editor configuration, and points to the organization for VS Code and other editor extensions. |
| Intended users | The project describes GNU GLOBAL as useful for hacking on large projects with many subdirectories, conditional compilation blocks, and main functions. | The project positions Shebe for developers and AI coding agents working with large codebases and says it complements structural tools such as Serena MCP. |
| License | GNU GLOBAL is free software that may be copied, modified, and redistributed under the GNU GPL. | The GitHub organization lists the Shebe repository under the Apache-2.0 license. |
| Purpose | GNU GLOBAL is a source code tagging system for locating objects such as functions, macros, structs, and classes in source files. | Shebe is a local code-search tool that uses BM25 full-text search for code repositories. |
| Support | The project directs users seeking help to the [email protected] mailing list. | The project provides installation, configuration, troubleshooting, and MCP setup guides in its repository. |

In their own words
Shebe
Shebe is a local code-search tool that uses BM25 full-text search across code repositories. It ranks results and supports phrase searches, Boolean queries, and literal matching. Fourteen MCP tools serve coding agents with functions including search, repository indexing, file reading, and reference finding. Shebe runs without embeddings, a GPU, or a cloud service, but repositories must be cloned locally before indexing; remote repository URLs are not supported. Its text-based search does not provide semantic similarity, so related words such as “login” and “authenticate” may not match. Prebuilt binaries are listed for Linux x86_64 and macOS on Apple Silicon and Intel; Linux ARM64 is planned. Windows users need to build it from source. The installation guide covers MCP setup and Zed configuration and points to the organization for VS Code and other editor extensions. Shebe is free and licensed under Apache-2.0. The README reports 2 ms query latency and indexing rates from 1,928 to 11,210 files per second in its listed benchmarks.
