Unchained Engine

A headless e-commerce platform for teams that want to own their code and data. It's built by a Swiss company, runs on Node.js with a GraphQL API, and can be hosted on any cloud or on-premise. It fits the headless commerce category, with no licensing fees or revenue sharing.

Agencies, startups, B2B sellers, marketplace builders, SaaS companies and event organizers are the main audiences.

• GraphQL API: typed queries, real-time subscriptions and auto-generated documentation.
• AI Copilot: built on the Model Context Protocol, it connects any LLM to your store to query products, process orders and generate product copy. It also sits inside the admin dashboard.
• Admin dashboard: real-time analytics, inventory management, bulk product editing and order workflows.
• Catalog and pricing: unlimited variants, multi-language, multi-currency, and custom pricing logic such as B2B tiers or date ranges.
• Payments: Stripe, PayPal, Datatrans, and other providers through plugins.
• Subscriptions and ticketing: recurring billing, plus event tickets with Apple and Google Wallet passes.
• Security: PCI DSS SAQ-A, WebAuthn passkeys and audit trails.
• Events: Redis Pub/Sub, AWS EventBridge and webhooks.

The codebase is split into 28 modular packages and runs stateless in Docker. A storefront template built with Next.js, TypeScript and Tailwind CSS gives you a starting point for design. Scaling relies on MongoDB sharding, edge caching and multi-region deployment.
