1. LangChain launches Mission Control, an in-cluster operations dashboard for self-hosted LangSmith on Kubernetes

LangChain. LangChain introduced Mission Control, an in-cluster operational interface for self-hosted LangSmith deployments on Kubernetes that runs without ingress, an external control plane, or an additional database. It performs preflight validation covering node capacity, Kubernetes version, DNS, storage class, and namespace quotas before any deployment proceeds, and ships a bidirectional Helm values editor with GitHub integration plus file uploads for air-gapped environments. A unified health dashboard surfaces pod CPU and memory, service readiness, workload logs, network topology, and PVC capacity. Built-in database tooling auto-discovers Redis, PostgreSQL, and ClickHouse with connectivity validation and CSV export for common diagnostic queries. Source
