Remote laboratories have become essential in modern education and research, enabling remote access to experimental setups. However, traditional server-based architectures present challenges in scalability, cost, and resilience. This paper introduces edrys-Lite, a browser-based, peer-to-peer remote laboratory platform that leverages WebRTC for real-time communication and Yjs for distributed state management. By eliminating the need for centralized servers, edrys-Lite offers enhanced scalability, improved resilience, and reduced operational costs. Additionally, the platform supports the collaborative creation and modification of laboratory modules as Open Educational Resources (OER), fostering an open-source ecosystem for educators and students. Implementation details and case studies demonstrate the feasibility and advantages of a serverless approach in delivering accessible, flexible, and cost-effective remote laboratories. This innovative architecture paves the way for scalable and resilient remote lab environments, promoting inclusive and collaborative scientific education and research.
