The open-source context layer for data agents

What it does

Kaelio is the company behind ktx, the open-source context layer that makes data agents reliable. Data agents today fail because they lack structured context and determinism. Metrics are defined in five places, governed in none. Teams spend months on semantic layer projects that never finish. ktx fixes that. Connect your warehouse, BI tools, and docs. ktx builds the context layer automatically. Your team governs it. Any agent can query it. One context layer across your entire data stack.

ktx: the open-source context layer for data agents

ktx teaches agents how to query your warehouse accurately. It learns your metric definitions, joinable columns, and business knowledge, then writes them as reviewable YAML and Markdown in git. Apache 2.0. Run locally.
