A developers agreement is a contract between two or more parties involved in the development of a software product. This agreement typically outlines the responsibilities of each party, the terms of collaboration, and any additional considerations that may come into play throughout the development process. It also serves to help ensure that all parties involved in the project understand their roles and expectations, while protecting the rights of all involved. By having a clear, comprehensive developers agreement in place, it can help guarantee peace of mind for everyone involved.
