Aeion Commerce vs Medusa
Medusa is a well-regarded open-source headless commerce framework — flexible, modular, developer-first. Aeion Commerce takes the same headless thesis and ships the surrounding operating system around it: 9 AI agents (fraud, review, churn, cart-recovery, product-copy, pricing, inventory, upsell, loyalty) + 20 payment-provider adapters (Stripe, PayPal, Square, Adyen, Klarna, Razorpay, Mercado Pago, Coinbase, etc.) + native Bridge POS hardware integration — ready to deploy, not assembled from parts. Build the storefront; Aeion already built the rest.
What Medusa Actually Gives You
Medusa is the right comparison when you're an engineering-led team building a custom storefront. The pitch:

When Medusa Wins
Be honest about where Medusa is the better choice:
Migration FAQ
Yes — the data model maps cleanly. Products, orders, customers, carts, regions (→ stores), subscriptions all have direct counterparts. Plan ~2-3 sprints for data migration + cutover with overlap period. Migration playbook included.
Yes — register Medusa via the generic webhook integration; commerce events fan out to both during a transition window.
No. Aeion is a managed, multi-tenant platform, not a framework you self-host — that's exactly why it ships with 9 AI agents, 20 payment adapters, and native POS support already built and maintained, instead of primitives you assemble yourself. You still get full API access and can export all your data at any time.
Medusa Cloud is the hosted version of Medusa OSS with per-month + per-order pricing. Aeion's flat $79/mo price has no per-order fee; you compare Medusa Cloud's order-volume pricing against Aeion's flat monthly price.
Yes. Each agent is a dedicated, tested worker with cost-cap enforcement, auto-subscribed to the relevant commerce events (e.g., a new order triggers the fraud-detection agent).
Different shapes for different teams.
Medusa is the right tool when commerce IS your product and you want to self-host every layer. Aeion is the right tool when commerce is one part of your platform — alongside CRM, CMS, identity, fleet, helpdesk, and so on. The 9 AI agents and 20 payment adapters are differentiators that compound as your customer count grows; Medusa users typically build versions of these themselves.
Headless flexibility, ready to deploy.
9 AI agents. 20 payment adapters. Native POS. Zero assembly required.
