Bagisto is an open-source eCommerce and multi-vendor marketplace platform built on Laravel and Vue.js. It provides a flexible, customizable foundation for launching online stores, B2B commerce portals and marketplaces, and aims to cut the time and cost of development while leaving room to customize and scale.

It is written in PHP and suits agencies and in-house teams that already know Laravel. The repository links to documentation, an installation guide, a Docker installation path and community forums, and the 2.x line was in beta at the time of writing.

Bagisto is MIT licensed, so you can host it on your own servers and modify it freely. It is a fit for merchants who prefer an open codebase over a hosted store builder, and for developers building custom commerce experiences who want Laravel conventions rather than a proprietary platform.

EverShop is an open-source ecommerce platform built with TypeScript, GraphQL and React. It is designed for developers and provides essential commerce features in a modular architecture that can be customized extensively, so teams can build tailored shopping experiences without starting from scratch.

The platform can be started quickly from a Docker image, which saves installing dependencies by hand, and a full installation guide is available.

WooCommerce is a customizable ecommerce platform that runs on WordPress, written mainly in PHP. The GitHub repository is a monorepo with the plugins, packages and tooling for developing the core WooCommerce plugin together with its extensions, so it is where the project's code, issues and development discussions live.

Developers working on it need Node.js, PNPM, PHP 7.4 or higher and Composer, and a POSIX-compliant operating system is assumed, with WSL recommended on Windows. The project maintains a development blog and a developer account on X for updates, and the topics reference React, since parts of its admin interface use it.

Because it is built on WordPress, merchants typically run WooCommerce on their own hosting, adding products, payments and shipping through extensions. The repository lists the license as Other, so check the licence terms in the repository. It suits small and mid-sized shops, agencies and developers who already work in the WordPress ecosystem.

It is cross-platform on Windows, Linux or Mac, supports Docker out of the box, works with web farms and Azure, uses async methods throughout and offers multi-factor authentication. Its pluggable architecture makes it straightforward to add custom functionality, and the project offers documentation and an online course for developers.

The GitHub repository contains the source code for development and preview, while stable downloads come from the releases page. The stable line is PrestaShop 9.0, first released in June 2025, and the develop branch holds work in progress toward version 9.1. Installing it requires a web server with PHP 8.1 or newer and MySQL 5.6 or later, or a compatible fork such as MariaDB, plus a database tool such as phpMyAdmin. Apache or Nginx are recommended.

OpenCart is a free and open-source e-commerce platform for online merchants. It is a PHP-based shopping cart system that you install on your own web hosting and use as the foundation of an online store, with JavaScript and HTML on the storefront side.

The repository includes installation and upgrade instructions that ship with the download, and the project directs users to a community forum, a GitHub bug tracker and a changelog for the master branch. Bug reports must relate to the core code, since problems with third-party modules or server configuration are referred back to the extension developer, the forum or commercial partners. Security issues are handled through private messages to moderators instead of public posts.

Contributions follow a documented guide covering environment setup, coding standards and pull request expectations. The repository lists a licence of other, so check the project for its exact terms before redistributing. A hosted version of the store software is not described in the repository.

It can also run as a hybrid headless CMS through GraphQL and REST APIs.

The project highlights a small resource footprint, caching that makes pages load like static files, a bundled SEO plugin, brute-force and SQL injection protection, a hidden admin login page and an install where only one PHP file is publicly exposed. It needs PHP 7.4 or later, with 8.3 recommended, and a MySQL, SQLite or PostgreSQL driver. It is licensed under AGPL-3.0.
