Versions:
D2 is a modern diagram scripting language developed by Terrastruct, Inc., designed to convert plain text into professional diagrams through declarative code. Currently at version 0.7.1 and backed by 21 incremental releases since its introduction, the tool targets software architects, DevOps engineers, technical writers, and anyone who needs to visualize system flows, cloud topologies, database schemas, or organizational hierarchies without dragging-and-dropping shapes. By writing concise D2 syntax—similar in spirit to Markdown but purpose-built for diagrams—users define nodes, connections, labels, and styling in a single file that the compiler renders into SVG, PNG, or PDF outputs. The language supports automatic layout engines, responsive grids, and theme packs, enabling revision-controlled, diff-friendly documentation that can be generated in CI pipelines or edited collaboratively in any text editor. Typical use cases include generating architecture decision records, onboarding runbooks, incident-response playbooks, and API reference overviews, all of which stay synchronized with evolving codebases because the source is text. As a specialized authoring tool within the Diagramming category, D2 integrates with popular static-site generators, IDEs, and cloud repos, and its open-core model encourages community contributions while offering commercial extensions for advanced shape libraries and real-time multiplayer editing. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
