Review their portfolio to evaluate the quality and diversity of their work. Look for developers who have experience with the specific technologies your project requires. Additionally, consider their communication style and responsiveness during initial conversations.

On the other hand, agencies typically have a team of professionals with diverse skills, which can lead to a more comprehensive approach to your project. They often provide ongoing support and can handle larger projects, but may come at a higher price point. Consider your project needs and budget when deciding.
