The Polymer Project offers a range of tools to help developers write web components:

  • The Polymer CLI is our recommended "swiss army knife" for Polymer tooling. It supports a collection of commands for common scenarios like serving, testing, and initializing new projects from templates.

  • The polymer.json specification describes how to configure your Polymer project and its builds.

  • Web Component Tester is an end-to-end testing environment built by the Polymer team.

  • The Web services page lists helpful services to speed up the development process.

For information on the build and deployment processes for Polymer applications, see the Polymer App Toolbox section.
