About APP Development Platforms
App development platforms are services that let you build, deploy, and run applications without managing the underlying infrastructure. They handle common tasks like authentication, databases, and hosting, so you can focus on your product logic and user experience.
The platforms on this list differ in approach, scale, and pricing. Some, like Firebase and DigitalOcean App Platform, are managed backends for developers. Others, like Stacker and Glide, turn spreadsheets into apps for non-coders. Tooljet and Expo target specific developer workflows, while Okteto focuses on AI agent environments. Pricing ranges from free tiers to usage-based and per-user models.
