For Engineering Teams

Architecture documentation your whole team actually uses

Stop losing architecture knowledge when engineers leave. Archyl gives your team a single source of truth for system design -- powered by AI discovery and kept in sync with your codebase.

Architecture Documentation for Engineering Teams | Archyl

Give your engineering team a shared architecture understanding with collaborative C4 diagrams, AI discovery from code, living documentation, and drift detection.

Knowledge silos across the team

Architecture knowledge lives in a few people's heads. When they leave or switch teams, critical system understanding walks out the door.

Onboarding takes too long

New engineers spend weeks piecing together how the system works from outdated docs, tribal knowledge, and reading code file by file.

Diagrams are always outdated

Architecture diagrams in Confluence or Draw.io become stale the moment they are created. Nobody updates them because the process is manual and disconnected from code.

No shared vocabulary for architecture

Teams use different names for the same services, draw boundaries differently, and miscommunicate about system structure in design reviews.

AI discovers architecture from your code

Connect your repositories and let AI automatically identify systems, containers, components, and their relationships. Start with reality, not a blank canvas.

Drift detection keeps docs in sync

Get a 0-100% health score showing how accurately your documentation reflects your actual codebase. Set thresholds in CI/CD to prevent drift.

Collaborative C4 diagrams

Visual drag-and-drop editor and Architecture as Code (YAML DSL) let every team member contribute. Change request workflows ensure quality.

MCP server for AI-assisted development

Engineers can query architecture context from Claude, Cursor, or Windsurf through 191 MCP tools. Architecture knowledge is always one question away.

Architecture Change Requests

Propose, review, and merge C4 model changes with pull-request-style workflows that the whole team can participate in.

Architecture Decision Records

Document the why behind architecture decisions and link ADRs directly to the C4 elements they affect.

Webhooks for Slack, Teams & Discord

Get notified in your team channels when architecture changes occur or drift scores degrade.

Declare your C4 model in archyl.yaml, version it in Git, and sync from CI/CD. Engineers work with familiar tools.

Layer ownership, deployment, or status information on top of your C4 diagrams for different team perspectives.

Full platform localization for distributed teams across English, French, Spanish, German, Chinese, Japanese, Portuguese, Korean, and Italian.
