The honest take

Where Eraser shines

Eraser has genuine strengths. If these matter most to you, it may be the better fit.

Beautiful, polished UI

Eraser features a clean, modern interface with thoughtful design decisions. The editing experience is smooth, and the rendered diagrams look professional out of the box.

AI diagram generation (DiagramGPT)

Eraser's DiagramGPT can generate diagrams from natural language prompts, making it fast to create initial visualizations. Users can describe what they want and get a rendered diagram instantly.

General-purpose diagramming

Eraser supports architecture diagrams, sequence diagrams, ERDs, flowcharts, and more. It is not limited to C4 or architecture, making it useful across many documentation needs.

Where Archyl goes further

What you get on top of the C4 model itself.

AI-powered discovery

Discover architecture elements straight from your codebase. No manual diagramming to get started.

MCP server, 191 tools

Give Claude, Cursor and other assistants the architecture through 191 specialised MCP tools.

Drift detection

A conformance score and alerts when the code moves away from the documented architecture.

DORA metrics

Deployment frequency, lead time, change failure rate and recovery time, next to architecture health.

Webhooks

Real-time notifications to Slack, Teams or Discord when the architecture changes or drift degrades.

Nine languages

The whole platform in English, French, Spanish, German, Chinese, Japanese, Portuguese, Korean and Italian.

Switching

Moving from Eraser to Archyl

A typical migration path, from export to a living model.

1

Identify your architecture diagrams

Review your Eraser workspace and identify which diagrams represent architecture documentation. Focus on system architecture, service maps, and C4-style diagrams.

2

Model your architecture in Archyl

Create your C4 model in Archyl using the visual editor or YAML DSL. Unlike Eraser's flat diagrams, Archyl creates a structured model with systems, containers, components, and relationships.

3

Enhance with AI discovery

Connect your code repositories and let Archyl's AI discover architecture elements from your actual codebase. This goes beyond prompt-generated diagrams to find your real architecture.

4

Establish architecture governance

Set up drift detection, conformance rules, ADRs, and change request workflows. Transform your architecture documentation from static diagrams into a governed, living model.

OverviewEraser alternatives

Questions teams ask before switching

How does Archyl's AI compare to Eraser's DiagramGPT?

Eraser's DiagramGPT generates diagrams from text prompts — useful for quick visualizations. Archyl's AI discovers architecture from your actual codebase by analyzing repositories, finding real systems, services, and their relationships. One illustrates ideas; the other discovers reality.

Can Archyl do general-purpose diagramming like Eraser?

Archyl focuses on C4 architecture documentation and adds flow diagrams and whiteboards. For general-purpose diagrams like flowcharts, ERDs, or wireframes, Eraser may be more appropriate. For architecture documentation, Archyl offers significantly deeper capabilities.

Is Archyl as easy to use as Eraser?

Yes. Archyl has a modern drag-and-drop visual editor with a clean UI and intuitive navigation. The learning curve is comparable to Eraser, with the additional depth of C4 model support and architecture governance features.

What does Archyl offer that Eraser does not?

C4-native modeling with structured hierarchy, AI architecture discovery from code, drift detection with conformance scoring, MCP server with 191 tools for AI coding agents, DORA metrics, ADRs, change request workflows, release management, technology radar, API contract management, and event channel tracking.
