Ember

Ember's strong defaults and zero-config approach minimize setup time, allowing developers to focus on building features rather than configuration, as highlighted in the README's 'Zero Config Apps' feature.

Built-in Ember Data provides powerful data handling with support for custom backends through adapters and serializers, enabling seamless integration with any stack, as mentioned in the 'Data Layer' section.

With regular LTS releases and 30 weeks of security fixes, Ember ensures application reliability and security, making it ideal for long-lived projects, as emphasized in the README's 'Reliability & Security' point.

High-quality, rated addons often require no additional configuration, supercharging apps easily, as noted in the README's description of the addon ecosystem on Ember Observer.
