Codebase intelligence for documentation, AI context, health analysis, and safer software changes Repowise is codebase intelligence software that analyzes source code, dependencies, call relationships, Git history, ownership, tests, security signals, and architectural decisions. It converts this evidence into a reusable codebase model, source-linked documentation, dependency graphs, health scores, change-risk analysis, and grounded answers for developers and AI coding agents. Repowise supports MCP tools for Claude Code, Cursor, and other compatible clients, as well as hosted repositories, GitHub pull request reviews, team workspaces, and self-hosting through its AGPL-3.0 open-source core.

Free, open-source diagram engine with AI, Mermaid.js support, and Figma vector export. OpenFlowKit is a 100% free, open-source diagram engine designed for engineers, architects, and product teams. It allows users to create professional architecture diagrams and flowcharts using either a visual drag-and-drop interface or 'Diagram as Code' with Mermaid.js and a type-safe DSL. Powered by React Flow, it offers a local-first experience where data stays on the user's machine, requiring no signup or cloud synchronization. It also features an AI assistant called Flowpilot for chat-based diagram editing and a unique Figma export that provides editable vector shapes.
