Nucleus vs Orbit
Last updated: 2026-09-14
Dromlik offers two plans built for different needs: Nucleus, a clean, no-complexity phone system for small teams, and Orbit, a full customer experience (CX) stack that adds contact centre, video, omnichannel messaging, and CRM integrations on top of everything in Nucleus.
If you're unsure which plan fits, Orbit is the safer default — it includes all of Nucleus's calling features plus the tools growing teams tend to need next.
