MCP servers, clients, registries, gateways, and agent tools built around the Model Context Protocol.
Databases, pipelines, and analytics
Open Data Stack
Source-visible databases, data pipelines, analytics, BI, and catalog tools evaluated as parts of a modern data stack.
Metrics, logs, traces, and incidents
Open Observability Stack
Source-visible observability, monitoring, logging, tracing, and incident-response projects compared across one operational ecosystem.
