Axon

Axon — graph-powered code intelligence engine with interactive web dashboard. Force-directed graph visualization, Sigma.js/WebGL rendering, health scores, coupling heatmaps, and hybrid semantic search. 711 stars, Python, MIT — but no commits since late March 2026.

Key takeaways

  • Graph-powered code intelligence engine with the best visual tooling in the category — interactive force-directed graph (Sigma.js + WebGL), community hull overlays, coupling heatmaps, and health scores
  • Shipped v1.0 in March 2026 with a PyPI package (axoniq), an MIT license, and hybrid semantic search (BM25 + 384-dim local embeddings + fuzzy matching with Reciprocal Rank Fusion)
  • Three dashboard views: Explorer (graph visualization), Analysis (health metrics), and Cypher Console (raw graph queries). Fully local — no API keys, no code leaves your machine
  • 711 stars, Python. Development has stalled — no commits since March 25, 2026 (~11 weeks as of June 2026). The visualization-first alternative to GitNexus and CodeGraphContext

FAQ

What is Axon?

A code intelligence engine that indexes codebases into a knowledge graph and provides an interactive web dashboard with force-directed graph visualization, health scores, coupling heatmaps, and a Cypher query console. Also exposes MCP tools for AI agents. Installs via pip as axoniq; everything runs locally.

Is Axon still maintained?

Uncertain. The repo is not archived and shipped v1.0.0/v1.0.1 in March 2026, but the last commit was March 25, 2026 — roughly 11 weeks of silence as of June 2026, with 30 open issues. Treat it as a working but possibly dormant single-maintainer project.

How does it compare to GitNexus?

GitNexus has deeper MCP integration (hooks, skills, 7 tools) and a far larger community, but uses a noncommercial license. Axon has significantly better visualization tooling (WebGL graph, heatmaps, health dashboard) and is MIT-licensed, but development has stalled since late March 2026.

Status (as of June 11, 2026)

Axon is alive but stalled. The repo is not archived and sits at 711 stars (up from 559 in March 2026) with 115 forks, but the last commit landed March 25, 2026 — roughly 11 weeks of silence — and 30 issues sit open. The latest release, v1.0.1, shipped March 9, 2026 alongside the axoniq package on PyPI. The installed tool works today; whether it keeps evolving is an open question.

Overview

Axon is a graph-powered code intelligence engine that differentiates itself through visualization. While GitNexus and CodeGraphContext focus on MCP tool depth, Axon provides an interactive web dashboard with force-directed graph rendering (Sigma.js + WebGL), community hull overlays, coupling heatmaps, and codebase health scores.

The indexer runs a 12-phase pipeline covering dependencies, call chains, type relationships, community clusters (Leiden algorithm), execution flows, dead code detection, and git history coupling analysis. A single axon analyze . command processes a typical repo in under 5 seconds. It supports Python, TypeScript, and JavaScript, and everything — parsing, graph storage, embeddings, search — runs locally with no API keys.

Key stats: 711 stars, 115 forks, Python, MIT license. Created February 2026; v1.0.1 released March 9, 2026.

Pricing

Free and open source under the MIT license (the license was unspecified at the time of the original profile; the repo now carries MIT). Install via pip install axoniq (Python 3.11+); the web UI ships in the package with no Node.js required. There is no hosted or paid tier.

What's New Since March 2026

  • v1.0.0 / v1.0.1 releases (March 8–9, 2026) and publication to PyPI as axoniq
  • MIT license added — the original profile flagged "no license specified"; that gap is closed
  • Hybrid semantic search — BM25 full-text + 384-dim vector embeddings (BAAI/bge-small-en-v1.5, computed locally) + fuzzy matching, merged with Reciprocal Rank Fusion. The final merged commits (March 25) refactored embedding management and background processing
  • Pluggable storage — KuzuDB by default, optional Neo4j backend behind a StorageBackend protocol
  • Growth then silence — stars rose from 559 to 711, but commit activity stopped March 25, 2026

Dashboard Views

  1. Explorer — Interactive force-directed graph. Click nodes to see code, callers, callees, impact radius, and community membership
  2. Analysis — Health score, coupling heatmap, dead code report, inheritance tree, branch diff
  3. Cypher Console — Write and run Cypher queries with syntax highlighting and presets

Competitive Position

Strengths: Best visualization in the category. Fast indexing (~4s for 142 files). Dead code detection and git coupling analysis are unique features. MIT-licensed where GitNexus is PolyForm Noncommercial. Fully local with hybrid semantic search.

Weaknesses: Smaller community (711 stars vs GitNexus's ~14k). Less mature MCP integration than GitNexus. Single-maintainer project with no commits since March 25, 2026 and 30 open issues — a real abandonment risk.

Cautions

  • Stalled development — ~11 weeks without a commit as of June 2026. v1.0.1 works, but bugs filed against it (30 open issues) are not being triaged
  • Bus factor of one — essentially all development is by the founder (harshkedia177); the March 25 merge activity was the maintainer's own embedding refactor branches
  • Young codebase — created February 2026; only four months of history, most of it in the first five weeks

What Developers Say

No verbatim, attributable developer reviews of this Axon were found as of June 2026 — searches across Hacker News and Reddit surface unrelated projects named Axon (an agentic-AI approval framework, a Kubernetes agent framework, and ali-kamali/Axon.MCP.Server) rather than firsthand usage reports of harshkedia177/axon. Its visibility is limited to MCP directory listings (Glama, LobeHub). The 711 stars and 115 forks are the only public adoption signal.

Bottom Line

Recommended — with eyes open — if you want the best code-graph visualization available and an MIT license: the v1.0.1 release is installable today, runs fully local, and the Explorer/Analysis/Cypher dashboard remains unmatched by GitNexus or CodeGraphContext.

Not recommended as a production dependency or for teams that need active maintenance: no commits in ~11 weeks, 30 untriaged open issues, and a single maintainer mean fixes may never come.

Outlook: Axon hit v1.0, got a license and PyPI distribution right, then went quiet. If commits resume, it is the strongest visualization-first player in code intelligence; if the silence continues through summer 2026, treat it as a finished artifact rather than a living tool.
