CodeBoarding

CodeBoarding turns a codebase and its pull requests into architecture diagrams, so reviewers can see what a change does to the system rather than reading every line of the diff. Its engine draws the components of a repository from the code itself and shows how they connect, then highlights which components a pull request modifies and which new dependencies it introduces. It positions itself as a review layer for software increasingly written by AI agents. It is aimed at engineers and teams reviewing large or agent generated pull requests. A GitHub Action posts a Mermaid change diagram and a summary table on each pull request, listing changed components, file counts and dependencies. The same pull request can be opened as an interactive diagram, read component by component, and the context copied into a coding agent's next prompt. An extension is available on the VS Code Marketplace and on Open VSX for Cursor, Windsurf and compatible editors, and diagrams export to PNG. Analysis runs in the customer's GitHub Actions runner, and bringing your own model key lets the runner call the provider directly. The command line engine is MIT licensed and runs locally. Pricing is published. Free costs $0, covers public and private repositories, includes metered analyses each month and diagrams three levels deep, and needs no card. Pro costs $9.99 per month and adds unmetered analyses, diagrams ten levels deep, faster generation, health monitoring and iterative changes. Enterprise is custom priced and adds custom environments and integrations, priority support and early access, with invoiced billing.
