About Heroku
Heroku is a platform-as-a-service (PaaS) owned by Salesforce that lets developers deploy and scale applications in the cloud without managing infrastructure. It supports Node.js, Ruby, Python, Java, PHP, Go, and other runtimes via buildpacks. Heroku eliminated its free tier in November 2022. The platform offers two runtime foundations: Cedar (traditional, broad service access) and Fir (Kubernetes-powered, with enhanced observability). It is particularly popular with startups and teams wanting fast deployment with minimal DevOps overhead.
