Graft vs xerj

Graft: Graft is an open-source context layer designed to accelerate and optimize coding agents like Claude Code, Cursor, and Gemini by providing deep contextual understanding of large codebases. It builds a human-readable code graph and linked markdown nodes, enabling agents to operate faster, cheaper, and with higher correctness by avoiding repeated code exploration.; 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.

TL;DR

Graft logo
GraftCode Assistant · ★ 10.7k
When to choose:
  • You want to generate a readable, interconnected Markdown knowledge graph of your repository so coding agents (Claude Code, Cursor) can grep and explore without expensive re-indexing.
  • You want to reduce context token waste by giving agents precise map-like documentation of modules and call paths.
When to skip:
  • You need an enterprise graph database with semantic vector embeddings and Cypher queries; code-graph-rag with Neo4j fits that scale.
  • You only have a small, single-file script or a trivial repository.

Features

Graft logoGraft
01Generates a human-readable, linked markdown graph of the codebase for contextual understanding.
02Provides real explanations of system parts and their connections, bypassing redundant agent exploration.
03Automatically refreshes the code graph against the working tree for real-time accuracy, even with uncommitted edits.
04Supports multiple LLM providers for generating summaries, allowing users to use their preferred models and keys.
05Acts as a local, regenerable cache (`graft/` folder) that is not committed to version control.
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
