Archyl
AI-powered C4 architecture diagrams from Git code, synced as YAML.
Archyl is the strongest choice for C4-committed teams who want to automate diagram creation from code. Its AI discovery and YAML DSL cut manual work dramatically, and the free tier is generous for evaluation. However, the C4-only focus limits appeal to teams using other modeling standards like UML; those teams should look at Structurizr or IcePanel instead.

Skip Archyl if you don't use the C4 model or need diagrams in other formats like UML, as it's strictly C4-focused and lacks flexibility for other modeling standards.
Going past the monthly AI discovery or chat query caps on Free (50) or Business (500) plans requires upgrading or paying for a higher tier.
Archyl's per-seat pricing is straightforward: Free ($0), Business ($25/editor/mo), Scale ($50/editor/mo). For C4 teams, it competes with IcePanel (~$20/user/mo) and Structurizr (open-source, self-host). Archyl's free tier is more generous than most, and the BYO AI provider option can make the Business plan effectively unlimited, appealing to mid-size teams. Enterprises needing SSO/on-prem will pay a premium on Scale.
In short
Archyl — AI-powered C4 architecture diagrams from Git code, synced as YAML. Best for Software architects documenting large codebases, Development teams using C4 model for communication, Tech leads onboarding new engineers into existing systems. Free to start; paid plans from $25/mo.

About Archyl
Archyl is a SaaS platform that helps software teams automatically generate and maintain C4 model architecture diagrams from their codebases. It uses AI to discover structure, containers, components, and relationships directly from Git repositories, transforming static documentation into interactive, versioned diagrams. Designed for architects, developers, and technical leads, Archyl supports the full C4 hierarchy (System Context, Containers, Components, Code) and offers a YAML-based Architecture as Code DSL to keep diagrams in lockstep with code changes. Beyond auto-discovery, Archyl provides a rich visual editor with drag-and-drop relationship mapping, overlays for highlighting architectural concerns, and drill-down navigation across abstraction levels. It imports existing Architecture Decision Records (ADRs) and Markdown docs, and exports diagrams via MCP server and REST API for integration into CI/CD pipelines. What sets Archyl apart is its AI-first approach: repo-wide AI discovery, streaming chat for real-time architecture queries, and managed agent runs that automatically refine structural insights. Teams can also bring their own AI provider (OpenAI, Anthropic, Google Gemini, AWS Bedrock, or OpenAI-compatible endpoints) to bypass usage quotas. With per-seat pricing, a free tier, and on-premise deployment for enterprise, Archyl targets both individual developers seeking quick visibility and large organizations needing governance and SSO.
Behind the Verdict
Most diagramming tools force you to draw boxes and lines by hand, then watch them rot as the code moves on. Archyl takes a different bet: point it at a Git repo and its AI discovery builds the C4 structure for you. If you're already bought into the C4 model, that's a huge time-saver—the four levels map directly to how many teams already think about their systems. Where Archyl shines is keeping documentation honest. The Architecture as Code YAML DSL means your diagrams live in version control, and the Architecture Drift Score flags when the reality of the codebase has wandered from what the diagram claims. We've seen too many architecture docs become fiction; this is a genuine fix for that. The pricing is competitive for per-seat tools—$0, $25, and $50 per editor per month—and the free tier gives you real AI capabilities, not just a trial. The bring-your-own-AI-provider option is a clever workaround for quota limits; we like that you can plug in OpenAI, Anthropic, Gemini, or Bedrock and skip the per-month caps entirely. But Archyl is not for everyone. The C4 model is the only game in town here. If your team uses UML, Archimate, or just a freeform whiteboard style, you'll be fighting the tool. Non-software teams—hardware or infrastructure-only—will find little value. And if your architecture is purely conceptual, still being designed, there's no code to discover, so you'd be doing all the drawing manually. Compared to Structurizr, which is the open-source C4 standard, Archyl trades that flexibility for automation; you give up the plain-text-first approach for a richer UI and AI agent that actually reads your code. IcePanel is another C4 option, but it lacks the code-discovery angle. For teams that live in the C4 world, Archyl's automation edge is real. For everyone

Real-world workflow fit
Concrete scenarios for the personas Archyl actually fits — and what changes day-one when you adopt it.
Onboarding a new repo with 200k lines of code
Outcome: You connect the GitHub repo, run AI Discovery, and get a System Context plus Containers diagram in under 10 minutes, drastically reducing manual mapping time.
Team wants to document a new microservice's architecture
Outcome: You use the streaming AI chat to ask 'What components does this service have?' and get an instant breakdown, then export the diagram via MCP to attach to the PR for review.
Every push should update architecture diagrams
Outcome: You set up a pipeline using the MCP server to trigger diagram regeneration, keeping documentation in lockstep with code changes and alerting the team via the Slack bot when drift is detected.
Use Cases
- Automatically generate System Context diagrams from a new Git repository within minutes.
- Drill down from a container-level view to individual classes and methods using AI chat.
- Import ADRs from a repository to visualize architectural decisions alongside diagrams.
- Set up a CI pipeline that updates architecture diagrams on every push using the MCP server.
- Evaluate architecture drift by comparing current code structure against stored diagrams.
- Use the YAML DSL to collaboratively edit architectures as code in pull requests.
Models Under the Hood
as of 2026-08-18
Limitations
- AI Discovery, AI Chat, and Managed Agent runs have monthly usage limits depending on the plan; purchasing a Scale plan or connecting your own AI provider (OpenAI, Anthropic, Google Gemini, AWS Bedrock, or OpenAI-compatible endpoints) removes these quota limits, with your provider invoicing you directly.
- On-premise deployment and SSO (SAML/OIDC) are only available on higher tiers, and the tool is primarily focused on C4 architecture diagramming.

Switching to or from Archyl
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Structurizr: Export your C4 model as DSL/JSON and import via Archyl's YAML DSL or AI Discovery from your git repo.
- →From manual diagrams (draw.io, Miro): Use AI Discovery to regenerate diagrams from code, then manually adjust in the editor via drag-and-drop.
- ↗To Structurizr: Export your C4 model as DSL/JSON and migrate since both use C4 concepts.
- ↗To IcePanel: Use Archyl's YAML DSL to extract structure and manually recreate diagrams in IcePanel's editor.
