As AI technology advances, choosing the right platform is crucial for your team's speed, governance, and long-term success. Both Sealos and Heroku have their strengths. The sections below compare them across developer experience, scalability, and total cost of ownership.
As AI technologies evolve, delivering and scaling applications has become essential for powering modern businesses, from AI startups to large-scale enterprises. There are various solutions available, including comprehensive cloud operating systems, managed Platform-as-a-Service (PaaS), and traditional IaaS. Selecting the right platform is crucial for your team's velocity, governance, and long-term success.
Sealos and Heroku both bring unique strengths to application delivery, each with its own capabilities and limitations. The best choice depends on your specific use case and requirements. In the following sections, we'll compare both platforms regarding developer experience, scalability, and total cost of ownership, helping you determine the most suitable option for your needs—even if it's not us.

Sealos is an AI-native Cloud Operating System built on Kubernetes that unifies the entire application lifecycle, from development in Cloud Development Environments (CDEs) to production deployment and management. It is perfect for building and scaling modern AI applications, SaaS platforms, managed databases (MySQL, PostgreSQL, Redis, MongoDB) and complex microservice architectures. The platform is 100% source-available, and for production you can choose either a fully managed cloud service or self-host on your own infrastructure.
Heroku is a mature Platform-as-a-Service (PaaS) built around git-based deployment and buildpacks. It runs applications on dynos (managed Linux containers), pairs seamlessly with the Heroku CLI and GitHub integration, and offers Pipelines, Review Apps, and a large add-ons marketplace. The platform abstracts infrastructure details for teams that want a fast path from code to production with a predictable, dyno-based pricing model.
