(open full size in a new tab)Our take: Archyl suits engineering teams that want C4 architecture diagrams generated from their repositories and kept in sync, starting on a free Developer plan.
Main limitation: Paid per-editor prices load by script and were not visible, and monthly AI usage limits apply unless you bring your own AI provider.

Archyl connects to GitHub, GitLab or Bitbucket repositories and uses AI to map systems, services and dependencies into interactive C4 diagrams, then keeps them in sync as code changes. It also includes architecture decision records, a YAML-based Architecture as Code format, an architecture drift score, and an MCP-based agent hub with conformance guardrails.

Scenarios are worked out by our editors from the documentation; the actual result depends on your input and plan.

Renders C4 models at levels from system context to code. Makes architecture easy to explore.
Reads source code with AI to map systems, services and dependencies. Avoids drawing by hand.
Defines C4 architecture in a declarative YAML file under version control. Keeps docs reviewable in CI.
Scores how far the code has drifted from documented architecture. Flags stale docs.

Export: archyl.yaml
An API is available, billing not documented. REST API and webhooks stated on the homepage.
Summarized from the vendor's current policies; this is not legal advice and a vendor's badge is not an independent audit.
Repositories are analysed for architecture discovery.
SSO and on-premise are higher-tier features.
"Better suited" is based on documented features and pricing, not on a head-to-head test.
