Open-source Webflow alternatives

WordPress is a content management system and publishing platform for building websites, blogs and apps. People write and organize content in a browser-based editor, choose how the site looks with themes, and publish without writing code. Its own site describes it as the platform behind millions of websites, from creators and small businesses to enterprises.

Design and editing are built around blocks, so pages can be assembled and rearranged visually with a live preview as content changes. Styling can be adjusted for different screen sizes and interactive states without writing CSS. Functionality is extended through a large library of plugins that add features such as stores, analytics, newsletters and social media integration.

The software is written in PHP and is open source; the GitHub repository is a read-only mirror of the project's Subversion repository, with development happening elsewhere. You can run it on your own hosting, and a managed service is also available through WordPress.com. It suits individual bloggers, small businesses and larger organizations alike.

Onlook is an open-source, visual-first code editor for building websites, prototypes and designs in Next.js and Tailwind CSS. Edits are made directly on the browser DOM with a Figma-like interface, while the changes are written to real code, so design and development share one source of truth.

You can create a Next.js app from text or an image or start from templates, then edit it visually, manage brand assets and tokens, create pages, browse layers and manage images. Developer tools include a real-time code editor, checkpoints you can restore, branching for design experiments, a CLI, an app marketplace, one-click deploys, shareable links and custom domains. Team collaboration is on the roadmap.

The README describes this repository as the open-source editor that started Onlook, while the hosted product for AI-native designers is in early access through a waitlist. It is licensed under Apache-2.0 and presented as an open alternative to tools such as Webflow, Figma Make, V0, Replit Agent, Lovable and Bolt.new. It suits designers who want to ship real code and developers who want a visual layer.

Builder is the visual development platform from Builder.io, and this repository holds its SDKs, usage examples, starter projects and plugins. The platform connects to an existing site or app so teams can edit visually and generate code using their own components, starting from Figma designs or a drag-and-drop editor.

Updates can be published through the SDKs or exported as code. The SDKs cover frameworks such as React, Vue, Svelte, Angular, Qwik and React Native, and the topics also mention headless CMS use, landing pages, Shopify and Next.js. A free account can be created to try it out, and a community forum handles questions.

The code in this repository is MIT licensed and written in TypeScript, but the editing platform itself is a hosted commercial service rather than software you host. It suits front-end teams that want non-developers to build and update pages from a shared component library.

Instatic is a self-hosted content management system with a visual editor, content engine and publisher all running in a single Bun server. It is presented as an open-source alternative to Webflow, Framer and WordPress, and aims to replace the usual pile of separate services for CMS, framework, hosting, forms and analytics.

One server holds the canvas editor, content engine, media, authentication, forms, plugins and the publisher, with users, roles and a database included, backed by SQLite or Postgres. Pages it generates are plain semantic HTML with compact CSS, without framework runtime or builder attributes, so they behave like static files. The README suggests one-click deployment on Railway, with options for Render and Docker or a VPS with Caddy TLS.

Instatic is MIT licensed and very new: the repository was created in April 2026 and the latest release is v0.0.20, so expect rapid change. It targets developers, designers and small businesses who want to own their site stack and keep the published output lean.

Webstudio is a visual development platform, released as open source, for developers, designers and cross-functional teams, and is presented as an alternative to Webflow. It is a visual builder that connects to any headless CMS and supports all CSS properties, and you own the data, components and infrastructure.

You can choose the hosted version or deploy your own instance, and the topics mention Cloudflare Workers, React, Remix and accessibility via Radix UI. The project provides a blog, documentation, a roadmap and an issue tracker for the builder, and a community on Discord.

Licensing is split. The Webstudio core, meaning all functionality in the repository, is free and open source under AGPL-3.0-or-later, while the optional sdk-components-animation package is proprietary and requires accepting the Webstudio, Inc. EULA. It is written in TypeScript. It suits designers and developers who want Webflow-style visual building with the option to self-host.

Plasmic is a visual builder for the web that enables rapidly designing and building applications and websites, with code optional. Its distinguishing idea is codebase integration: you register your own React components so that marketers and designers can arrange them visually, which the project says removes the ceiling usually associated with low-code tools.

The README names three main use cases: content management, where marketing teams drag and drop React components to build landing pages in a Next.js site within design guardrails, applications such as internal tools, client portals and business software built quickly by developers and technical users, and a website builder and design tool that is not limited to a built-in ecommerce platform, CMS or hosting. It works with Next.js, Gatsby and other frameworks, and also acts as a headless CMS.

Plasmic is licensed under MIT and written in TypeScript, with documentation, a quickstart, a forum and a Slack community. The visual editor is offered as a hosted service at plasmic.app, and demos show examples such as a Shopify headless storefront. It suits front-end teams that want non-developers to build with their component library.

Craft is a flexible, easy-to-use content management system for building bespoke digital experiences, online and elsewhere. It offers an intuitive control panel for content creation and administration, and a clean-slate approach to content modeling that makes no assumptions about what you manage.

Developers build front ends with Twig templates, or go headless using the auto-generated GraphQL API. The platform also supports a full ecommerce solution for bespoke online stores, a Plugin Store inside the control panel offering hundreds of plugins, both free and paid, and an extension framework based on Yii2 for advanced customization. Repository topics list Twig, GraphQL, PHP 8 and several major Craft versions.

The code is source-available, and GitHub shows the license as 'Other' because Craft uses its own license, with free and paid editions offered by the vendor. Craft is self-hosted on your PHP server, and the vendor provides support and cloud hosting options. It suits agencies and in-house teams building tailored sites.

Microweber combines a drag-and-drop page builder with a content management system on the PHP Laravel framework. It aims to let people create websites, online stores and blogs without technical skills, while still giving developers a modern code base to extend.

The README describes an array of modules, customizations and features tailored for e-commerce, and the current 2.0 version runs on Laravel 10. A shopping cart and content management features sit alongside the visual editor, and the documentation covers system requirements, installation and getting started. Topics include website builder and drag-and-drop.

Microweber is MIT-licensed and can be installed on your own hosting. It suits small businesses, freelancers and agencies that want to build a site or store visually, on an open-source PHP stack they can still modify.

Silex is a visual builder for static websites that can also pull in dynamic data. You design pages visually and export standard HTML and CSS that can be hosted anywhere, so there is no proprietary format, forced hosting, or subscription. It is released under the AGPL-3.0 license and presented as an open alternative to Webflow.

It is maintained by Silex Labs, a non-profit organization, and describes itself as free forever with all features included and no premium tier. It follows JAMstack practices, uses the GrapesJS editor according to its topics, and can pull content from WordPress through GraphQL. An MCP server is also mentioned among the project topics, and a desktop app can be downloaded alongside the online version.

You can try Silex online or run it yourself with Node.js. It suits web agencies, WordPress developers, freelance designers, and no-code builders who want a visual workflow with output they fully own. Because the output is standard web files, learning it also builds transferable HTML, CSS, and JAMstack skills.

Frappe Builder is a low-code website builder designed for simplicity, speed, and flexibility. Designers can lay out pages visually, and developers can customize them. A click-to-publish option covers the end-to-end process of making a site live. It is part of the Frappe ecosystem, written with Python, Vue, and TypeScript, and released under the MIT license.

The author says existing tools were too complex, too restrictive, or hard to integrate with Frappe, and that pages made with them often carried unnecessary scripts and styles. Builder aims to produce lean pages. The topics mention responsive layouts, Figma, a CMS, ERPNext website integration, and an AI website builder.

It suits teams already running Frappe or ERPNext who want to design public pages such as landing pages and marketing sites without leaving the platform, and developers who want a visual tool that integrates with their Frappe data. Documentation and a project website are available.
