Introduction

Eclipse Lyra is a modular web framework for building IDE-like applications with a plugin architecture, AI integration, and workspace management.

This documentation is for developers who want to:

• Build applications on top of Eclipse Lyra — define your app, pick extensions, and ship.
• Create extensions — add commands, sidebar tabs, toolbars, and custom UI that plug into the framework.

Live example

A full app built on Eclipse Lyra: https://app.kispace.de.

Repository

Source and issue tracker: github.com/eclipse-lyra/core.

Next steps

• Getting started — run the default app and build for production.
• Concepts — apps, extensions, contributions, and commands.
• Build your own app — scaffold with npm create @eclipse-lyra/app or set up manually in the monorepo.
