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

Third-party APIs change while your code depends on them: a model ID is retired, a field is removed, or an API version reaches end of life. Dependabot updates package versions, but it does not tell you which lines call the changed API. Upseam does. It reads vendor changelogs and deprecation notices for Stripe, Shopify, OpenAI, Anthropic, and Gemini, matches them against JavaScript, TypeScript, and Python code, and identifies the affected lines. Then it opens a pull request with the fix. It never pushes to your default branch. In Ask mode (the default), you approve each fix before a pull request opens, including simple fixes such as a renamed model ID. Install the GitHub App or run a one-off local report with npx @upseam/cli inspect. The local report requires no account or installation. Upseam is free during the beta.
