Textualize

Textualize is an open-source software ecosystem and organization that develops tools for building user interfaces within text terminals, primarily using Python. It is best known for the Textual framework, a library that enables the creation of interactive, richly styled terminal applications with a layout system, reusable widgets, and a CSS-like styling language. The Textualize ecosystem supports developers in constructing dashboards, CLIs, and other terminal-based tools by providing abstractions for event handling, rendering, and responsive layout.

The projects emphasize modern UI design principles such as component-based architecture, declarative configuration, and asynchronous programming. Applications built with Textualize tools can manage dynamic content, respond to keyboard and mouse input, and render complex or decorative content directly in terminal windows.

Textualize operates as an open-source project with public repositories, documentation, and community channels. Contributions are supported through established guidelines, issue trackers, and discussions, with an emphasis on cross-platform compatibility and accessibility within conventional terminal environments.

Historically, Textualize formed to coordinate ongoing development of Textual and related tooling beyond a single developer’s effort, aiming to foster a sustainable ecosystem for Python-based terminal user interfaces. The project has garnered attention among developers seeking more capable, visually engaging CLIs and monitoring dashboards.
