Archify: Interactive Architecture and System Diagrams for AI Coding Agents

Repositorytt-a1i/archifyTool

Archify is an open-source Node.js rendering and validation engine designed as a skill for coding agents like Cursor, Claude Code, Codex CLI, and OpenCode. Agents produce a typed JSON Intermediate Representation (IR), which Archify deterministically compiles into self-contained, interactive HTML, SVG, and media exports.

Key points

  1. Supports five diagram types: architecture, workflow, sequence, data-flow, and lifecycle maps.
  2. Deterministic rendering: Agents generate typed JSON IR that undergoes strict validation, preventing hallucinated topology.
  3. Architecture diffing: Enables pre-merge review of snapshots (Before, Delta, After) highlighting added, removed, moved, or rerouted connections.
  4. Rich export options: Outputs standalone interactive HTML with motion alongside SVG, PNG, WebM, and social share cards.
  5. Agent-native integration: Works out of the box via agent chat or npx in tools such as Cursor, Claude Code, and Codex CLI.

Why it matters

Developers frequently use AI assistants to navigate complex codebases, but standard diagrams like static Mermaid snippets often suffer from syntax errors or inaccuracies. Archify provides a verified, structured bridge between agent reasoning and reliable visual system design.

Analysis

Archify addresses a significant friction point in AI-assisted engineering: validating system design claims made by language models. By enforcing a structured JSON schema prior to compilation, it guarantees topological accuracy and reproducibility. The built-in snapshot comparison makes architectural review directly actionable within CI and PR workflows. Given its development stage at v2.17.0-dev.1 and more than 45,000 GitHub stars, Archify stands as a mature, widely adopted tool in the emerging coding agent ecosystem.
