LeIndex vs LXR Cross Referencer
Both stand on code search tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose LeIndex if you want repository search that combines keyword matching, structural analysis, and optional local neural scoring. It is also suited to AI coding workflows through its MCP server. Look elsewhere if you need semantic search without configuring an embedding backend, since the fallback is offline keyword search.
Visit LeIndexLXR is a free, self-hosted option for browsing indexed code with links between identifiers and their uses. Its setup work and parser limits make it important to check the installation and language-analysis fit for your project.

LeIndex: what it does well
- Search combines lexical matching with code structure.
- Can index and search multiple repositories together.
- Offers 20 MCP tools for code tasks.
- Local ONNX embeddings keep data on the machine.
- Free and distributed under the MIT license.
What to know first
- Without an embedding backend, search lacks semantic understanding.
- Model files must be downloaded separately with leindex setup.
- Remote embedding providers require network access and API keys.
LXR Cross Referencer: what it does well
- Links identifiers to definitions and uses.
- Supports several database and source-storage options.
- Full-text search is available for eligible repositories.
- Produces HTML for web browsers.
- Database browsing access is read-only.
What to know first
- Requires database, source-tree, and web-server setup.
- Parsers are not compiler-grade.
- Full-text search excludes CVS and BitKeeper repositories.
- New releases are posted only on Codeberg.
