Quickstart

Requires Python 3.10+, Git, a clean repository, and Claude Code or Codex.

python -m pip install "codenib[graph,mcp]"
codenib codegraph init /path/to/your/repo

Then ask your agent: “Use CodeNib's explore_context to find where request retry behavior is implemented. Cite the files and lines.”

This shipping path builds local search and a typed symbol graph, then connects installed agent clients. It needs no model, API key, or GPU for CodeNib; your agent uses its own model. It is separate from the grep/Jev experiment above. Language toolchain and project prerequisites vary.

Why CodeNib

• Inspect the evidence. Retrieve bounded code context with file and line references, then follow callers, callees, definitions, and references.
• Use the same tools across languages. The registry tracks 14 language entries, including 12 with graph backends. Check capability and setup differences in the language matrix.
• Compare methods on the same source. Pinned agent contracts, datasets, and scorer checks make the reproduction surface inspectable.
• Share what you found. Export a Wiki with source citations to your own GitHub Pages, or browse the public examples.

How it compares

“Local” and “key” describe the repository tool, excluding the agent's model. This compares capabilities, not benchmark scores.

Tool	Local processing	Tool needs a model/key	Graph / navigation	Languages	Updates
grep / read	Yes	No	Text and files	Any text	Current files
CodeNib CodeGraph	Yes	No	Typed SCIP/LSP graph	14 chunkers / 12 graph entries	Reuse unchanged views; rebuild changed views
Serena	Yes	No retrieval model	LSP/IDE symbol navigation and editing	Backend matrix	Backend-managed project state
CodeGraph (colbymchenry)	Yes; telemetry opt-out	No	Typed AST-derived graph	20+; upstream matrix	File watcher and incremental sync
DeepWiki public MCP	Hosted	No user key	Wiki and generated answers	Public indexed repos	Service-managed

Detailed comparison, sources and boundaries. CodeNib 0.2.4 also includes an optional grep → Jev route using OpenRouter for planning and reranking; selected code goes to remote models. Authorization previews remain opt-in. The historical research result above is separate from the product evaluation and the model-free CodeGraph row.

Languages

Graph backends: Python, Go, Rust, C/C++, C#, Java, Ruby, PHP, Kotlin, Scala, JavaScript, and TypeScript. Swift and Lua support chunking/retrieval. Provider prerequisites and coverage differ by language.

The generated language matrix separates chunking, graph backends, incremental-backend support, and decoder parity. The product currently reuses or rebuilds views; file-level delta repair is not enabled.

Results and reproductions

Start here	What you can inspect
grep → Jev result	100-issue retrieval comparison, candidate controls, model use and limitations
Agent integration matrix	Revision-pinned LocAgent, Agentless, CoSIL, OrcaLoca and RepoNavigator contracts; compatibility does not imply reproduced paper scores
Dataset and benchmark matrix	CodeNib Base/Synthesis, SWE-bench variants, Loc-Bench and SWE-Explore support
SWE-Explore validation	1,020/1,020 real-output metric cells match the pinned official evaluator on a fixed 20-case run
DGX Spark deployment	Local Wiki, CodeGraph and model serving on GB10; a deployment guide, not a token-saving benchmark
