Building a video app is no small undertaking that requires careful consideration of budget, resources, timeline, use case, and more. With the increasing demand for video engagement, businesses must weigh their options between investing in an out-of-the-box provider like Zoom or Twilio Video, or building their own custom solution using open-source solutions like WebRTC. The choice ultimately depends on the organization's culture and skills necessary to build, deploy, support, and scale complex systems, as well as their specific needs for customization and scalability. A thorough understanding of APIs, user experience, and platform choices is crucial in making an informed decision that meets business requirements while also ensuring a seamless user experience.
