Your Magento Bill Hit $4,200 Last Month. Here's Your Exit.

Moving from Magento to MedusaJS cuts your platform licensing fees from $22,000 -- $125,000 per year to exactly $0, replaces a monolithic PHP application with a modular Node.js commerce engine, and gives you full ownership of your data and infrastructure. The migration is complex -- expect 12 to 20 weeks -- but the five-year total cost of ownership difference is $66,000 to $185,000 in your favor compared to staying on an enterprise-licensed platform.

If your Magento bill hit $4,200 last month, you are not alone. We have run this migration for merchants who were paying Adobe Commerce licensing, plus specialized PHP hosting, plus Magento-certified developers at premium rates -- all for a platform where every upgrade felt like defusing a bomb.

Why are Magento merchants switching to MedusaJS?

The short answer: money and velocity.

Magento (Adobe Commerce) licensing runs $22,000 to $125,000 annually before you write a single line of custom code. MedusaJS is open source with zero licensing fees. Your only platform costs are hosting and development.

The annual cost breakdown tells the story clearly:

• Magento total annual cost: Licensing ($22K -- $125K) + hosting (Varnish, Redis, dedicated CDN) + specialized Magento developers ($30K -- $100K+ development)
• MedusaJS total annual cost: $0 licensing + $3,600 -- $8,400 hosting + $24,000 -- $48,000 development = $28,800 -- $60,000

Over five years, MedusaJS runs $144,000 to $300,000 total. That is not a rounding error -- it is the difference between hiring two more people or not. If this math looks familiar, it is the same arithmetic that drives merchants away from Shopify's fee structure and toward open-source alternatives.

MedusaJS also charges zero platform transaction fees. You pay your payment provider (Stripe, PayPal, or whatever you wire up) and nothing else. No GMV tax. No percentage skimmed off every order.

How does MedusaJS actually compare to Magento on performance?

This is where the gap gets embarrassing for Magento.

Medusa's own benchmarks using the k6 load testing tool -- with both platforms running on identical server hardware -- show that MedusaJS API response times are on average 6 times faster than Magento's. Specific numbers from their 95th percentile tests:

• Single product fetch (1 user): MedusaJS is 4.3x faster
• Concurrent load (10 users, 30 seconds): MedusaJS is 6.0x faster
• Concurrent load (25 users, 30 seconds): MedusaJS is 11.0x faster
• Concurrent load (50 users, 30 seconds): MedusaJS is 7.3x faster
• Fetching 15 products simultaneously: MedusaJS is 6.0 -- 7.0x faster across user loads

Magento can perform well, but only after you bolt on Varnish caching, Redis servers, and a dedicated CDN -- each adding cost and operational complexity. MedusaJS is lightweight and API-first by design. Your storefront (built in Next.js) serves statically generated pages from a CDN. The MedusaJS backend handles cart, checkout, and order processing via API. They scale independently.

This is the same architectural principle we apply when helping clients escape other monolithic platforms, whether that is a Sitecore migration or moving off a bloated LMS like Teachable.

What does the Magento to MedusaJS migration actually involve?

We are not going to sugarcoat this: it is a high-complexity migration with a 12 to 20 week timeline. But it is a well-understood process with defined steps.

Data export and transformation:

• Products (including configurables, bundles, grouped products) exported via Magento's REST API and direct database access
• Categories, custom attributes, and product relationships mapped to MedusaJS data structures
• Customer records migrated with order history intact
• Product images moved to cloud storage (S3 or equivalent)
• Customer passwords require a reset flow -- Magento's bcrypt hashes are not portable to MedusaJS, and anyone who tells you otherwise is lying

Backend configuration:

• MedusaJS backend stood up with PostgreSQL database
• Payment providers wired in (Stripe, PayPal, or custom integrations via MedusaJS payment modules)
• Shipping and tax rules configured
• Custom business logic ported -- and this is often where MedusaJS shines. Custom discount logic that takes 6 hours in Shopify takes roughly 3 hours in MedusaJS because the module system is designed for exactly this kind of extension

Frontend rebuild:

• Storefront built in Next.js, connected to MedusaJS via API
• Static generation for product and category pages
• Cart and checkout flows built against MedusaJS endpoints

Testing and cutover:

• Full regression testing across the catalog
• Payment flow validation
• Order processing verification
• DNS cutover with rollback plan

The risk level is medium to high, which is why we plan cutover windows carefully and maintain the Magento instance as a fallback until the new stack is validated in production.

When should you stay on Magento instead?

We are opinionated, but we are honest. There are cases where staying on Magento makes sense:

• You have 50+ custom Magento extensions that would need to be rebuilt from scratch, and the rebuild cost exceeds the five-year savings
• Your team is exclusively PHP and retraining or hiring Node.js developers is not viable in your timeline
• You need the Magento marketplace ecosystem right now -- MedusaJS has a growing ecosystem, but it is younger and smaller than Magento's extensive extensions marketplace
• You are on Magento Open Source (free) with modest hosting costs and your total annual spend is already under $30K

If you are on Adobe Commerce paying licensing fees, or if your hosting bill alone exceeds $1,000/month because you need Varnish and Redis just to keep page loads under 3 seconds, the math favors MedusaJS.

What about multi-currency and B2B -- where are MedusaJS's weak spots?

We believe in showing you the full picture. Developer productivity benchmarks show that certain tasks take longer in MedusaJS than in competing platforms:

• Adding a payment provider: ~8 hours in MedusaJS vs ~1 hour in Shopify Hydrogen
• Setting up multi-currency: ~12 hours in MedusaJS vs ~1 hour in Saleor, ~2 hours in Shopify

These are real costs. If multi-currency is central to your business, factor in the additional development time. That said, MedusaJS's native B2B modules handle customer groups and price lists without per-app fees or tier restrictions -- a meaningful advantage if you are running wholesale alongside DTC. For merchants comparing Shopify vs MedusaJS specifically, the B2B calculus often tips toward MedusaJS once you are past three catalog segments.

What does your infrastructure look like after migration?

Post-migration, your stack is yours. Fully.

• Database: PostgreSQL, which you control, back up, and query directly
• Commerce engine: MedusaJS, self-hosted or on Medusa Cloud ($99 -- $299/month)
• Storefront: Next.js on Vercel, Netlify, or your own infrastructure
• Payments: Direct relationship with Stripe, PayPal, or your processor -- no platform fee layered on top
• Data: You own it. Full schema control, full export capability, no vendor lock-in

For merchants in regulated industries or with data sovereignty requirements, this is not a nice-to-have -- it is a hard requirement. The same principle applies whether you are evaluating your CMS costs or your commerce platform: owning your data means you are never held hostage by a renewal invoice.

The real cost of waiting

Every month you stay on Adobe Commerce, you are paying licensing fees for a platform whose architectural decisions were made in the mid-2000s. The $4,200 you spent last month becomes $50,400 this year, and $252,000 over five years -- before hosting, before development, before the next forced upgrade that breaks your custom modules.

MedusaJS is not magic. It requires real engineering to set up, real planning to migrate to, and real operational discipline to maintain. But it is a modern, modular commerce engine that runs on the most widely known programming language in the world, costs nothing to license, and performs 6x faster than the platform you are trying to leave. The five-year savings of $66,000 to $185,000 compared to enterprise-licensed alternatives are not theoretical -- they are the direct result of eliminating licensing fees and reducing infrastructure complexity.
