C4 model diagrams with comment-to-Claude feedback loop through Channels.

Strengths

•C4 model structure (Context, Containers, Components, Code) stored in queryable YAML
•Interactive HTML diagram sends comments back through Claude Channels for real-time updates
•/architect:init generates diagrams from existing codebases, not just new plans

Weaknesses

•Requires Claude CLI and Plan Mode — narrow audience within already-niche tool
•Diagram is local HTML file, no collaboration or sharing features built in

Post Description

Introducing Claude Architect Make Plan Mode feel like a whiteboard session

Architect is a plugin to create interactive architecture diagrams you can review, annotate, and revise with Claude.

Coding agents one-shot prototypes, but production systems need more steering. Long prompts and many rounds of back-and-forth in the terminal can feel draining.

I built this because I love whiteboard sessions with engineers. It's the easiest way to grok the whole system, spot relationships, and point out feedback.

Architect makes Plan Mode feel like a whiteboard session: 1. Review the architecture at a glance 2. Drill down into containers and components 3. Comment directly on any node or edge 4. Review Claude's updates

Under the hood, Claude builds a semantic model of the architecture using the C4 model: Context, Containers, Components, Code. The model is stored in YAML and rendered as SVG diagram. Claude receives your comments through a Channel and updates the plan + diagram together

I'd love feedback. How would you use this? What features do you want to see next?

Layerd – Layered system architecture diagrams with 3D visualization

The layer-first canvas and a clear components palette (Services, Databases, Queues, Line Keys) make expressing front-end/back-end/data separation quick and visual. The 2D↔3D toggle is a neat flourish for showing stack depth and ownership, but without visible integrations (Terraform/Cloud import, export/collaboration, or smart layout) it reads as a nicer-looking competitor to existing diagram tools rather than a workflow disruptor.
