NationBuilder has community action and content pages built into a full-featured and customizable CMS. Your website is directly integrated into your contacts database, as is social media. It’s just more advanced than Salsa Lab’s products like DemocracyInAction. NationBuilder also supports voter data and outreach.
Here’s what Liberal Art has to say about NationBuilder vs. Salsa+Drupal: “NationBuilder’s tool suite is competitive with competing platforms, but its tools are fully integrated into the CMS. This means less setup and easier management of your messaging and action campaigns. What’s more, social sharing functions are baked into every page, tool, and action taken by your supporters.”
