reposkein vs xerj

reposkein: RepoSkein gives an AI coding agent a map of your codebase. It uses Tree-sitter to build a deterministic Code Property Graph of files, classes, functions, imports and call edges, stored in plain files with no database or Docker, and served over MCP.; xerj: XERJ is a single Rust binary that auto-indexes any folder (code, docs, logs, CSV, PDFs) for BM25, vector and hybrid search behind an Elasticsearch-compatible API. It plugs into Claude Code, Cursor and other MCP clients so agents retrieve exact passages instead of reading files one by one.

Features

reposkein logoreposkein
01Deterministic graph: same code gives a byte-identical graph, with no LLM in construction
02Zero-infra: the graph lives in .reposkein/*.jsonl files
03Supports Python, TypeScript, JavaScript, Rust, Go, Java and C#
04Summaries written by agents are committed and travel with the code
xerj logoxerj
01xerj autoindex sniffs every file and creates typed indices with no schema or pipeline to write
02Code indexed with symbols and line numbers via tree-sitter, plus go-to-definition (xerj def)
03BM25 full-text, kNN vector and hybrid search behind an Elasticsearch-compatible API
04xerj init wires it into Claude Code or Cursor as an MCP server plus skill in one command
05/_memory namespaces give agents long-term memory recalled by meaning
