An online store you own end to end: OpenCart bundles the storefront, product catalog, checkout, and admin panel into one self-hosted install with no monthly software fee. Products take options and attributes, and master products can spawn variants that override price, SKU, and stock level. Unlimited categories, filters, reviews and ratings, coupons, specials, and reward points help shoppers find items and return for more. Guests and registered customers can check out by bank transfer, cheque or money order, or cash on delivery; subscription plans with trial periods handle recurring orders, and more gateways and carriers install from the extension marketplace. Shipping rules include flat-rate, free, per-item, pickup, and weight-based options. Tax classes, geo zones, and multiple currencies with automatic rate updates support selling abroad. One admin interface manages several stores, each with its own theme, layout, and language settings, and user groups control who may edit what. A built-in blog adds topics, articles, and comments with anti-spam rules, and language packs cover more than 40 languages, right-to-left scripts included. Sales, tax, shipping, product, and customer reports, campaign tracking, an affiliate program, bulk customer mail, GDPR export and removal tools, and downloadable digital goods round out the business side.

Where is ChatGPT Plus cheapest this week, and which seller actually honors the warranty? Price Comparison (Zhitu Shijia) is a self-hosted platform that gathers AI subscription and account offers from many card shops into one catalog you can search, compare, and question. Tell the built-in guide your budget and need, for example a Plus top-up under a monthly cap with warranty cover, and it filters offers, explains recharge channels and purchase conditions, and narrows the list through follow-up questions. Browse by platform, delivery method, term, and warranty to compare prices and stock for ChatGPT and Codex, Claude, Gemini, Grok, and Cursor offers side by side, including finished accounts, shared accounts, and redeem codes. Price history shows how an offer moved before you buy, and official regional prices give a reference point when a quote looks suspiciously cheap or expensive. Email accounts, SMS verification, and residential IP offers sit in the same catalog, so the extras a subscription needs can be priced in the same pass. Install the comparison Skill or connect the MCP service and your own AI assistant can search products, compare merchant quotes, and pull price history with source links and collection times attached. In the admin console you add and review shops, run collection, and supervise the pipeline that identifies, classifies, and publishes products into the catalog.

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.

BTCPay Server processes Bitcoin payments with zero transaction fees, zero monthly costs, and zero third-party custody of your funds. Payments settle directly from customer to your wallet through a full Bitcoin node that provides cryptographic proof of receipt without trusting any intermediary. Lightning Network integration through LND, Core Lightning, or Eclair enables sub-second confirmation at sub-cent fees, with Ride The Lightning providing web-based node management within BTCPay itself. The Point of Sale app creates storefronts with product catalogs, tipping, and QR code displays for physical retail, events, or web embeds. Hardware wallet support through BTCPay Vault connects Ledger, Trezor, and ColdCard for transaction signing, keeping private keys in cold storage while running a hot payment interface. Multi-tenant architecture allows multiple stores on one instance, each with isolated wallets, Lightning nodes, and user permissions. The Greenfield REST API exposes every function programmatically for headless operation, automated invoicing, and custom integrations. E-commerce connectors for WooCommerce, Shopify, Magento, and PrestaShop plug in alongside Zapier for workflow automation. Optional Tor hidden services expose the instance as an onion address for censorship resistance. The official Docker Compose stack handles Nginx reverse proxy, Let's Encrypt TLS, and optional Tor configuration on a dedicated RepoCloud VPS with guaranteed CPU, RAM, and SSD. MIT licensed.

With over 35,000 GitHub stars and 460 contributors, Medusa is the headless commerce framework that gives development teams full ownership of their e-commerce backend without license fees, per-transaction charges, or revenue sharing. The modular architecture ships over 18 domain modules covering products, collections, categories, inventory, pricing, carts, orders, payments, fulfillment, promotions, customers, users, API keys, and stock locations, each independently usable and replaceable. REST and GraphQL APIs expose every commerce operation to any frontend framework — official starters exist for Next.js with community options for Nuxt, Remix, and Gatsby. The React-based admin dashboard provides out-of-the-box order management, product maintenance, promotions configuration, B2B accounts, and multi-warehouse inventory, extensible via the Admin SDK for custom views and workflows. The workflow engine orchestrates long-running commerce processes like checkout, fulfillment, and returns with compensating transactions for reliability. Over 200 official and community plugins integrate Stripe, PayPal, Klarna, Algolia, Meilisearch, SendGrid, Mailchimp, Contentful, Sanity, and Klaviyo. Native multi-region and multi-currency support handles tax-inclusive pricing, region-specific payment and fulfillment providers, and localized storefronts from a single backend. Enterprises including Viessmann, Makro PRO, and INSPIRED Pet Nutrition run Medusa in production. Self-hosting deploys via Docker or directly on Node.js with PostgreSQL and Redis.

InnoShop runs your entire online store on your own server, from a multilingual storefront and checkout to orders, shipments, and returns, and it even lets an AI assistant operate the shop alongside you. Set up products with SKUs, attributes, brands, and categories, then sell through a responsive storefront that speaks your customers' languages and prices in their currencies. Orders flow into the admin panel with status updates, shipment tracking, and return handling, while customers pay through PayPal, Stripe, bank transfer, or payment and shipping plugins you install. A built-in media library keeps product photos and files organized and reusable across the whole catalog. Visit analytics show who is browsing the store, with bot detection and geographic aggregation separating real shoppers from crawler noise. The unusual part is the AI door: a built-in MCP server exposes more than 45 store operations as tools, so an assistant can list products, check inventory, update an order status, or pull a sales report in plain conversation. That door is disabled by default, opens only with an admin token, stays read-only until you explicitly enable write tools, and never exceeds the permissions of the account behind the token. Plugins extend the store without forking it, and themes reshape the storefront without touching the catalog underneath. 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.

Kill Bill handles the complete subscription billing lifecycle from plan definition through invoice generation to payment collection across any gateway, with 15 years of Fortune 500 production use and 5,600+ GitHub stars behind it.

GrandNode lets you run one shop, a dozen regional storefronts, or a full marketplace from a single installation, with a back office for every role involved. Each store gets its own domain, theme, currencies, languages, and settings, and a store manager panel limits staff to the catalog, orders, and customers of their own store. Outside sellers join through a vendor panel where they manage their own products and orders. The catalog handles attributes and combinations, bundles, grouped items, downloads, date-based reservations, and auctions. B2B selling adds customer groups, tier prices, sales employees, and approvals. Checkout accepts payments through plugins such as Stripe Checkout, Braintree, and cash on delivery, with shipping by fixed rate, weight, or pickup point and tax rules by country, state, or zip code. Marketing tools include coupon codes, discount rules, loyalty points, gift vouchers, customer segments, newsletter campaigns, and push notifications. Clean URLs, sitemaps, and structured data with price and availability help search engines read your products. Pages, blog posts, news, and sliders cover content, and a REST API serves headless storefronts and ERP or CRM integrations. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Marketplace apps take a large slice of every order, and NextOrders Food gives a restaurant its own ordering website instead. Customers land on a storefront carrying your brand, browse the menu, and check out under your domain, so the customer relationship stays with the kitchen. A city selector opens the right location storefront, which suits chains and ghost kitchens running several neighborhoods from one deployment. Menus speak to more guests with eleven or more bundled languages, from English and German to Georgian and Simplified Chinese. The cart stays visible on desktop during browsing, removing the hunt for the checkout button that loses hungry customers. Product pages can carry video, and the ordering flow highlights items frequently bought together, nudging a drink or side into the basket. Delivery and pickup are both supported at fulfillment, letting one menu serve couriers and counter collection. Pages render on the server as separate indexable pages, so search engines can find a city menu rather than a script shell. Behind the counter, the storefront talks to your backend through a typed food schema: your service supplies menus, prices, and order handling, and an example business logic service in the repository shows the contract working.
