# Flowdular Sandbox > The Flowdular sandbox turns a brief into a working module with your coding agent: a specification you approve, checked builds and a live preview, on your machine. The Flowdular sandbox is a local application that turns a business brief into a Flowdular module. It drives the coding agent you already use through a specification you approve, the platform gates and a live preview, then delivers the module as code. ## Sandbox - [Sandbox overview in Markdown](https://sandbox.flowdular.com/index.md): Steps, requirements and the launch command, generated from this page. - [Website](https://sandbox.flowdular.com/): The sandbox page with the recorded session. - [How it works](https://sandbox.flowdular.com/#how): The sandbox waits for you where it matters. Nothing is built before you approve the specification, and nothing leaves the session before the gates pass. - [What you need](https://sandbox.flowdular.com/#requirements): The sandbox brings the workspace, the gates and the preview. You bring the rest. - [Run it locally](https://sandbox.flowdular.com/#run): It creates or finds a Flowdular workspace, starts the app and serves the sandbox at http://127.0.0.1:4320. ## Developer resources - [Sandbox README](https://github.com/flowdular/flowdular/tree/main/packages/sandbox#readme): Launcher options, connecting and the security model. - [Flowdular](https://flowdular.com/): The platform the sandbox builds modules for. - [Source](https://github.com/flowdular/flowdular): The Flowdular repository. - [Module contract](https://github.com/flowdular/flowdular/blob/main/AGENTS.md): Rules every module follows. ## Optional - [License](https://github.com/flowdular/flowdular/blob/main/LICENSE): License terms. - [Sitemap](https://sandbox.flowdular.com/sitemap.xml): Canonical indexable pages.
