Our review of Lightdash agent

The Lightdash agent is a cloud‑only paid add‑on that builds on top of your existing Lightdash content. Setup is very simple — it pulls in your data and dbt semantics and adds a prompt layer — and it runs fast. However, configuration options beyond that initial setup are limited, which makes it hard to shape behavior for nuanced analytics use cases.
