# codegraph vs Archon

codegraph and Archon share 3 technologies: Vite, @clack/prompts, and xyflow. Both are written in TypeScript.

- [colbymchenry/codegraph](https://seerepo.com/r/colbymchenry/codegraph): Pre-indexed code knowledge graph, auto syncs on code changes, for Claude Code, Codex, Gemini, Cursor, OpenCode, AntiGravity, Kiro, CoPilot, and Hermes Agent — fewer tokens, fewer tool calls, 100% local
- [coleam00/Archon](https://seerepo.com/r/coleam00/Archon): The first open-source harness builder for AI coding. Make AI coding deterministic and repeatable.

## What they share and what sets them apart

- In common: Vite, @clack/prompts, xyflow
- Only in codegraph: Svelte, @fontsource/ibm-plex-mono
- Only in Archon: GitHub, Postgres, PostHog, Anthropic, Hono, React, React Router, bcryptjs, Zod, yaml, pino, pino-pretty, @agentclientprotocol/sdk, earendil-works, @opencode-ai/sdk, Ajv, Better Auth, Tailwind CSS, @dagrejs/dagre, Lucide, react-markdown, rehype-highlight, remark-breaks, remark-gfm

## Side by side

| | codegraph | Archon |
|---|---|---|
| Size | 522,800 lines written, 443 code files | 666,863 lines written, 1,890 code files |
| Who writes it | 78.4% of its commits signed by AI. With Claude Code, Codex, and GitHub Copilot | 12.7% of its commits signed by AI. With Claude Code, GitHub Copilot, CodeRabbit, and Gemini CLI |
| Activity | Last push November 1, 2026, 1,785 commits, 76,573 stars | Last push November 4, 2026, 3,643 commits, 23,825 stars |
| Tests | 1,002 test files. 47.9% of its code files have a test that imports them | 1,069 test files. 42.7% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
