Contentful is a popular choice for Jamstack sites due to its API-first approach, which enables the repurposing of content across multiple channels. The company's marketing team uses Contentful, Gatsby.js, and Netlify to build performant sites at scale, despite having only three developers on staff. This combination allows them to ship new web content quickly with confidence, thanks to features like instant rollbacks, deploy previews, and a streamlined workflow that automates the grunt work. By leveraging these tools, Contentful's team is able to empower their entire company to make content updates without relying on developer assistance, making it an ideal fit for the Jamstack ecosystem.
