Getting Started (Harper + Grafana)

Harper v5.0 introduces a VM-based JavaScript environment that enhances application isolation, security, and developer experience. With application-specific context, module-level separation, and protections against prototype pollution, unauthorized access, and supply chain attacks, it delivers a more secure, scalable foundation for modern distributed applications.
