Maintained at tt-a1i/archify (MIT), Archify is a Node.js rendering and validation system for Cursor, Claude Code, Codex CLI, and OpenCode. Agents author typed JSON IR; Archify deterministically checks schema, layout, and composition, then atomically delivers self-contained HTML. Architecture Delta compares two validated snapshots as Before / Delta / After with exact added, removed, changed, moved, and rerouted facts. It does not auto-parse Mermaid, host sharing, or offer WYSIWYG editing.
