## The Hook

Medusa is the MIT commerce engine you run when Stripe Billing is the wrong shape.

## What's Good

MIT. Self-host the commerce OS: products, carts, orders, regions, modules. Pitch is OSS on your infra. Cloud exists and starts From $29/mo (Develop) — verified on medusajs.com/pricing. No GMV tax on the pricing page.

## The Catch

Commerce OS, not invoices and not card rails. Cloud From $29/mo is not a $0 hobby hatch — self-host is the free path. Distinct from Polar/Hyperswitch (payments) and from Lago (metering).

## Verdict

MIT commerce OS. Self-host is free; Cloud starts at $29/mo.
