# CoreX

> Analytics, growth and automation for Shopify & Stripe app developers — live-captured MRR, churn, trials and retention cohorts, App Store listing and keyword tools, flows, email, help desk and AI agents.

CoreX is a workspace where app developers track and grow their Shopify and Stripe apps. This file lists the public, machine-readable surface an AI agent can use.
