## Description

Theia is a modular framework designed for building professional-grade development environments that function as both local desktop applications and remote browser-based services. It provides a comprehensive toolkit for constructing specialized coding tools, allowing developers to assemble custom interfaces and backend logic through a flexible, contribution-based architecture.

The platform distinguishes itself through a highly extensible workbench that supports the integration of existing third-party editor plugins and standard language servers. By utilizing a dependency injection container and a multi-process architecture, it enables the creation of tailored development experiences that maintain compatibility with established industry standards while offering deep customization of UI components, menus, and command structures.

Beyond its core construction capabilities, the framework includes integrated support for artificial intelligence, offering features such as natural language chat, automated code issue resolution, and context-aware coding assistance. It manages complex development workflows through task planning, automated script execution, and collaborative review processes, all while enforcing security policies through workspace execution restrictions and tool access controls.

The project is distributed as a ready-to-use desktop application and provides build pipelines for packaging custom environments into native installers for major operating systems.
