Behind a storefront you own sits PrestaShop, an open-source e-commerce platform that runs the catalog, the checkout, and the order desk. Products carry size and color combinations, features, brands, suppliers, and categories, CSV import loads products and customers in bulk, and Extra Properties adds custom fields with their own types to products, customers, and orders. The bundled One Page Checkout module, switched on from the back office, puts every checkout step on a guest-first page, and the four-page flow stays available. Hummingbird, the default theme, presents a mobile-optimized, accessibility-minded storefront, and native WebP and AVIF image support helps pages load faster. Staff handle orders, invoices, credit slips, abandoned carts, and returns, create orders by hand, and answer shoppers from the customer service page. Carriers, payment methods, taxes, currencies, languages, and shipping zones are configured in the back office, multistore runs several shops with separate settings, and the Update Assistant guides upgrades through backup, update, and restore. In the Classic edition, an Ask AI assistant answers questions from real store data and runs plain-language requests after asking your approval, using the provider and API key you connect. The Admin API connects ERP, order management, PIM, and marketing automation tools through scoped OAuth clients, and Addons marketplace modules extend the shop. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. OSL-3.0 licensed.

Bagisto is an eCommerce framework for businesses demanding full ownership and zero recurring platform fees. Built on Laravel 12 and Vue.js, version 2.4 supports seven product types — simple, configurable, virtual, downloadable, grouped, bundle, and booking — with multi-channel inventory management across unlimited warehouses and sales channels.

Magento's extensibility without PHP, Shopify's polish without the platform tax: EverShop is the TypeScript-first e-commerce platform built on that promise. Architected as a modular monolith on Node.js, it organizes every piece of business logic - catalog, checkout, customers, your custom extensions - into modules that plug in without touching core code, extended through a disciplined set of mechanisms: registry processors for transforming data across modules, hooks that wrap function calls, async event subscribers (product created, order placed), and route middleware. The storefront and the fully-featured admin panel are both React with server-side rendering and hydration, giving fast first paint and SEO-friendly pages, while a typed GraphQL API (plus REST endpoints) serves exactly the data each view needs - the same API that powers headless and PWA builds. Standard commerce is covered: product management with variants and attributes, category navigation, cart and checkout, order and customer management, coupons, and a theme system built on React components and Tailwind for deep storefront customization. PostgreSQL is the default database, deployment is Docker-friendly with near-zero configuration, and the GPL-3.0 license means the entire stack - types, resolvers, and checkout flow included - is yours to read and modify.

Backed by 23,000+ GitHub stars and trusted by global brands processing millions of orders, Saleor delivers the open-source headless commerce API that replaces monolithic ecommerce platforms with a composable, GraphQL-native architecture where APIs are the only way to interact with the system. The core engine built on Python and Django handles catalog management, order processing, payment orchestration, inventory tracking, and fulfillment workflows while remaining completely decoupled from any frontend technology. Native multichannel support enables per-channel control of pricing, currencies, warehouses, product availability, and payment methods, managing Instagram, Amazon, regional websites, and retail POS from a single backend. The extensibility layer provides 160+ webhooks spanning synchronous payment callbacks, asynchronous event notifications via Google Cloud Pub/Sub and AWS SQS, and subscription queries that shape webhook payloads to deliver only the data your services need. Dashboard UI Extensions offer 45+ mount points for embedding custom interfaces via iframes without forking, while the Apps system allows building payment gateways, PIM integrations, loyalty programs, and discount logic in any language.

Vendure is a headless ecommerce framework where TypeScript plugins extend every aspect of commerce without forking the core, backed by 8,200+ GitHub stars and powering stores processing over 10,000 daily transactions. Two distinct GraphQL APIs serve different audiences: the Shop API powers storefronts while the Admin API handles back-office operations, both introspectable and type-safe through Apollo Server. NestJS modules with Vendure decorators inject services, modify schemas, subscribe to events, and add dashboard components, making extensibility a first-class concern rather than an afterthought. The React admin dashboard built with TailwindCSS and Shadcn UI provides order fulfillment workflows, catalog management, tiered pricing, dynamic promotion rules with side-effect hooks for free gift injection, and role-based access control across 14+ languages.

Roughly 40 integrated business apps forming a full ERP: Odoo's open-source suite runs companies end to end. The Community Edition, licensed LGPL-3.0, ships roughly 40 apps covering CRM, sales, invoicing, basic accounting (journals, chart of accounts, taxes, reconciliation), inventory and warehouse management with multi-step routes, manufacturing with BOMs and work orders, purchasing, project management, timesheets, HR, a website builder, and eCommerce. Each app works standalone, but they share one PostgreSQL database and one data model, so a confirmed sale updates stock, triggers procurement, and posts invoices without integration glue. The modular design means you enable only the apps you need and extend with 40,000+ community modules from the Odoo app store covering nearly any vertical requirement. Inventory supports multi-warehouse stock, reordering rules, and lot and serial tracking with barcode-ready operations; manufacturing ties BOMs, work orders, and work-center routing directly to sales demand and stock levels; and the website builder sells straight from your product catalog with payment provider integrations. You can start with just CRM and invoicing on day one and switch on inventory or eCommerce later - new apps integrate with existing data instantly because the schema is shared. The server is Python with an XML/JavaScript view layer, and because data lives in plain PostgreSQL there is no proprietary format: you can query, back up, migrate, and extend business data directly, with unlimited users and no per-seat licensing - where enterprise ERP pricing is per user per month, headcount here costs nothing.

Roughly 43% of all websites and over 60% of the CMS market run on WordPress - the GPL-licensed platform that scales from a personal blog to publishing operations and WooCommerce stores. The Gutenberg block editor composes pages from reusable blocks, and full site editing extends block control to headers, footers, and templates; tens of thousands of plugins and themes cover essentially every capability a site might need, from SEO and caching to membership and e-commerce. WordPress 7.0 "Armstrong" marks the platform's biggest structural update since Gutenberg itself: a React-based DataViews admin replaces the legacy list tables with instant filtering, a provider-agnostic AI Client API ships with connectors for OpenAI, Anthropic, and Google, media processing moves into the browser via WebAssembly, and a universal Font Library manages typography across block, hybrid, and classic themes with local hosting for GDPR compliance. New Breadcrumbs, Icons, and lightbox Gallery blocks reduce plugin dependence, and server-side PHP block registration simplifies development. The REST API and WP-CLI make it automatable end to end. Self-hosting is what WordPress was designed for: your content, database, plugin choices, and upgrade schedule stay entirely under your control, free of wordpress.com plan limits.

No middleman, no custody, no private keys to hand over: Bitcart is a self-hosted crypto payment processor that settles every payment straight into your own wallet. Connect wallets with just a public key or address; receiving payments never needs a private key. Accept Bitcoin, Litecoin, Bitcoin Cash, Ethereum, Monero, Tron, stablecoin tokens, and Lightning payments, with each store mixing as many wallets as it needs for multi-currency checkout. Issue invoices with custom expiration, promo codes, and per-invoice payment methods, then get status updates through webhooks, Telegram, or email. A ready-made storefront with categories, price filters, discounts, and a cart sells products or digital downloads, while a keypad point-of-sale view with amount, discount, and tip modes covers in-person sales. Approve payouts, issue refunds, export invoices as CSV or JSON, and add extensions from the plugin marketplace in one click. Bring crypto checkout to WooCommerce, Shopify, WHMCS, FOSSBilling, or Odoo, or script your own flow through the REST API.

Hyperswitch from Juspay delivers the most comprehensive open-source payment orchestration stack available — a Rust-built platform that connects to Stripe, Adyen, Braintree, Worldpay, Checkout.com, Cybersource, and 120+ payment processors through a single API integration. Intelligent routing drives each transaction to the processor with the highest predicted authorization rate using rule-based, volume-based, and machine learning algorithms, while seamless failover and automatic retries recover revenue from declined transactions using 30+ parameters including decline codes, card BIN, transaction size, and region. The PCI-compliant card vault stores payment methods securely in a dedicated service separate from the main application server, and the reconciliation engine automates 2-way and 3-way matching with backdated support, staggered scheduling, and customizable audit-ready outputs. The Control Center dashboard provides visual workflow builders for routing rules, payment analytics, and operations management. Cost observability tools drill into scheme, interchange, and acquirer fees to detect anomalies and optimize processing costs. The modular architecture allows deploying individual components — routing, retries, vaulting, observability, or the full suite — without vendor lock-in. The web client SDK collects payment information with prebuilt UI components and supports WooCommerce integration. Deploy via Docker Compose with the app server, control center, card vault, and PostgreSQL.
