Architecture diagrams drawn by hand in a tool like PowerPoint or Miro tend to go stale fast — someone changes the system and forgets to update the picture. LikeC4 flips that: you describe your system's components and how they connect in a simple text format, and the diagrams are generated automatically from that description, so keeping the text current is enough to keep every diagram accurate. LikeC4 is a free, open-source (MIT license, ~5,100 GitHub stars) modeling language and toolset for software architecture visualization, built around the C4 Model (Context, Containers, Components, Code) and inspired by the Structurizr DSL, with added flexibility for customizable notation and nested architecture levels. It's written in TypeScript as a monorepo, ships a VS Code extension available on both the VS Code Marketplace and Open VSX, includes a CLI for local preview during development, offers a web-based playground to try it without installing anything, and supports multiple export formats.
