Thanks for the question! Just to complete - OpenVikings is context/memory infrastructure for agents. ktx is analytics context for data agents specifically. So they're in different categories

The way we think about the space: there's a "semantic layer" side (Cube, dbt MetricFlow, Wren's engine) that compiles correct SQL but is hand-authored. And a "company brain" side (OpenViking, Glean, wikis) that indexes prose but can't query data warehouses safely. ktx is built to be both halves at once - a YAML semantic layer and a searchable wiki of business definitions, cross-linked (each wiki page references the metrics it explains) and auto-maintained

Hey, ktx maintainer here! Great question, we actually have quite a bit in common with Wren, they're in the same category. The main difference is that with Wren you author the semantic model (write MDL) and it executes SQL through its own Rust engine (similar to Cube as well). ktx instead builds the context for you - ingesting definitions already in dbt, Looker, Metabase, and Notion, auto-detecting joins and fan/chasm traps, flagging contradictions. It also builds both : the SL and wiki that accumulates and maintains free-form tribal knowledge (that’s also interlinked with ktx SL)
