# Build on Pipeline

> Two integration paths: Pipeline Bridge for embedded tools, and the Public REST API for server-to-server.

Pipeline is built to be extended. Whether you're a developer at a trade business
building internal tools, or a software company integrating Pipeline into a larger
workflow - this section covers everything you need to build on top of Pipeline.

You can embed custom HTML/JavaScript tools directly into the Pipeline interface
using the **Pipeline Bridge**, or automate and sync data server-to-server using
the **Public REST API**. Both are designed to be straightforward to start with
and grow with your needs.
