Hiring a freelance Database Developer typically allows for more flexibility and direct communication, often at a lower cost. Freelancers can provide personalized attention and may be more adaptable to project changes. However, they may lack the resources or backup that an agency can offer.

They often come with established processes, but may be more expensive. Deciding between the two depends on your specific project requirements, budget, and desired level of support.
