# Introduction openBuild is a [framework](https://docs.openbuild.io/introduction/the-framework) for building Bubble apps professionally. It is the result of years of Bubble design and development experience packed into a Bubble template. {% hint style="success" %} Get the Bubble template here 👉 {% endhint %} {% hint style="danger" %} The 2.0 version of the openBuild extension, designed to work with the latest responsive engine, is currently in closed beta testing. The current version of the extension only works with the legacy template, which was built on the old responsive engine. The updated version of the extension will be made available to the public soon. {% endhint %} openBuild is built on top of [Bubble](https://docs.openbuild.io/core-concepts/bubble-vs-openbuild) and cannot be used as a standalone product. {% hint style="info" %} openBuild is a professional framework for Bubble.io. While its concepts are easy to understand and learn, it is not a beginner template. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
