MedusaJS Development

MedusaJS is the open-source alternative to Shopify and Commerce Cloud that is rapidly becoming the platform of choice for engineering-first e-commerce teams. Built with Node.js and TypeScript, Medusa gives you complete control over your commerce logic — without the limitations of a SaaS platform or the complexity of Magento. At Core Chunk, we specialise in MedusaJS development for brands that need a modern, headless commerce engine they can extend without limits.

What Makes MedusaJS Different Unlike Shopify, Medusa is open-source: zero platform fees, no revenue share, full code ownership. Unlike Magento, it is built on modern JavaScript/TypeScript, is lightweight, and deploys in minutes on any Node.js host. Unlike WooCommerce, it is headless by default — meaning your frontend (Next.js, Remix, mobile app) is completely decoupled from your commerce backend. This separation gives you the freedom to deliver your brand experience on any surface, from web to mobile to voice to kiosk, all from a single commerce API.

MedusaJS + Next.js Storefront The most popular MedusaJS stack pairs the Medusa backend with a Next.js storefront. Core Chunk builds custom Next.js storefronts on top of the Medusa Storefront SDK, delivering sub-second product page loads, seamless cart and checkout experiences, and pixel-perfect designs that match your brand. The result is a store that scores above 95 on Lighthouse and provides an experience that closed-platform stores simply cannot match.

Medusa Plugin and Module Development MedusaJS's plugin architecture allows every part of the commerce engine to be extended or replaced. We build custom Medusa plugins for: payment providers (Razorpay, PhonePe, PayU, Stripe), shipping providers (Shiprocket, Delhivery, India Post with real-time rate fetching), inventory sync with Zoho Inventory, Tally, or custom ERPs, custom fulfilment workflows, subscription commerce logic, B2B pricing and quote management, and marketplace seller management. If Medusa's core doesn't do it, a well-architected plugin does.

Medusa Deployment and Infrastructure We deploy Medusa on scalable cloud infrastructure — Railway, Render, AWS ECS, or DigitalOcean — configured with PostgreSQL, Redis for caching and event queuing, and S3-compatible object storage for media. We set up CI/CD pipelines for automated testing and deployment, ensuring every code change is verified before it reaches production. For high-traffic operations, we configure horizontal scaling and load balancing to handle traffic surges without downtime.

Why MedusaJS is the Right Choice for Indian Brands in 2026 For Indian brands that are scaling fast, frustrated by Shopify's limitations and fees, and want modern developer tooling, Medusa is the right move. It supports Indian payment gateways natively via plugins, allows you to build GST-compliant invoice generation into the order workflow, and gives your team the ability to iterate on your commerce experience without waiting for a platform to release a feature. Core Chunk has built end-to-end Medusa commerce systems for brands that needed commerce infrastructure that grows with them — not against them.
