About
Astah Professional is an all-in-one modeling tool for software and system design, developed by Change Vision, Inc. It supports UML 2.x, ER diagrams, data flow diagrams (DFD), flowcharts, requirement diagrams, CRUD, and mind maps in a single tool.
Unlike drawing tools, Astah creates models: a change to a model element is reflected in every diagram that uses it, so your diagrams stay consistent.
AI features include AI Chat Copilot and AI-assisted code reverse engineering, which use your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service. A local MCP server lets external AI agents work with your Astah models. Conventional reverse engineering of Java, C#, and C++ code is also included.
Astah Professional is a desktop application for Windows, macOS, and Linux, with a bundled Java runtime, so no separate Java installation is required. A 20-day free trial is available.
Latest version: 12.0 (released July 15, 2026).

About
LocalAI is a free, open source, local-first AI platform designed as a drop-in replacement for the OpenAI API, allowing developers to run large language models and other AI systems entirely on their own hardware without relying on cloud services. It provides a complete AI stack for local inferencing, enabling text generation, image creation with diffusion models, audio transcription and speech synthesis, embeddings for semantic search, and multimodal capabilities such as vision analysis. It is compatible with OpenAI API specifications, allowing existing applications to integrate seamlessly by simply switching endpoints, while supporting a wide range of open source model families that can run on CPU or GPU, including consumer-grade devices. LocalAI emphasizes privacy and control by ensuring all processing happens locally, keeping data on-device and eliminating external dependencies.
