The stack you already run on.
Connect the systems you already pay for — commerce, data warehouse, engineering, product analytics, and collaboration. Lumen is read-only for everything except PR review on GitHub and code delegation through Cursor, both of which are opt-in and admin-gated.

Lumen adds integrations based on what customers actually need. If you rely on something that isn't listed, tell us — we'll scope it honestly and share a date.
