Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
KeystoneJS integrates multiple technologies (Node.js, Express, MongoDB) which may be overwhelming for developers not familiar with these ecosystems.
While KeystoneJS is flexible and can integrate with various services, it lacks extensive pre-built integrations compared to more mature frameworks or platforms.
KeystoneJS may experience performance degradation when handling large volumes of data or high traffic, especially without proper optimization and scaling strategies in place.
The framework's tight coupling with MongoDB might not suit projects requiring different database systems for scalability or performance reasons.
