Archyl vs LikeC4: C4 Model Tool Comparison

Compare Archyl and LikeC4 for C4 architecture documentation. See how AI discovery, drift detection, and enterprise features extend an open-source C4 DSL.

Open-source DSL for C4 diagrams meets AI-powered architecture platform

LikeC4 is an open-source tool with a flexible DSL for creating C4-style architecture diagrams, featuring custom element kinds, a VS Code extension with LSP, and embeddable React components. Archyl builds on C4 modeling with AI-powered discovery, drift detection, enterprise collaboration, and the ability to import directly from LikeC4.

Flexible type system beyond strict C4

LikeC4 lets you define custom element kinds beyond the standard C4 hierarchy (System, Container, Component). You can model microservices, queues, databases, or any domain-specific concept as first-class elements in your DSL.

Developer-friendly DSL with great IDE support

LikeC4 provides a VS Code extension with full Language Server Protocol (LSP) support, offering autocompletion, validation, and syntax highlighting. Hot reload makes iteration fast and seamless.

Open source and embeddable

LikeC4 is fully open source under the MIT license. Its React components can be embedded directly in documentation sites, wikis, or custom applications for interactive architecture visualization.
