DigitalOcean App Platform is a managed Platform-as-a-Service (PaaS) for deploying web apps, APIs, and background jobs. You define your app in a YAML appspec file, push to GitHub, and the platform handles containerization, scaling, load balancing, and deployment. It supports Python, Node.js, Go, Ruby, PHP, and static sites. Developers don't need to manage Kubernetes clusters or SSH into servers—the platform abstracts infrastructure away. Startups and small teams adopt DO App Platform because it's 10x simpler than AWS or GCP and 3-5x cheaper than Heroku for sustained workloads. Every developer should know how to ship apps without managing infrastructure. DigitalOcean is seeing 40%+ growth in adoption as SMBs seek alternatives to Heroku's price increases.
