Alternatives / Webflow
Looking for an open source Webflow alternative? We compared 13 open source visual website builders, CMS platforms, and AI design tools by license, self-hosting, CMS features, and pricing. They range from true visual builders to headless CMS platforms and code-editing tools.

| Alternative | Best for | License |
|---|---|---|
| Onlook | Visually editing Next.js code with AI | Apache-2.0 |
| Webstudio | Closest visual builder with full CSS | AGPL-3.0-or-later core |
| Builder.io | Visual headless CMS (platform is proprietary) | MIT SDKs / proprietary hosted platform |
| Plasmic | Visual builder that outputs React | MIT + AGPL-3.0 (platform) |
| Webiny | Serverless CMS on AWS (paid editions) | MIT core / Enterprise components |
| Drupal | Complex content sites | GPL-2.0-or-later |
| Frappe Builder | Drag-and-drop pages on Frappe | MIT |
| Silex | Static sites with 11ty | AGPL-3.0 |
| Grida | Canvas design tool for developers | Apache-2.0 |
| Vvveb CMS | CMS with builder and ecommerce | AGPL-3.0-or-later |
| Frontman | AI agent editing code in the browser | Apache-2.0 integrations; AGPL-3.0 server with AI Supplementary Terms |
| Ycode | Visual builder with a built-in CMS | MIT |
| Nordcraft | Web engine with collaboration (not fully open yet) | Apache-2.0 (engine packages) |
We looked for open-source tools that overlap with Webflow's core: designing websites visually, managing content, and publishing without hand-coding everything. We verified each project's license, recent activity, stars, and self-hosting in its repository. Webflow is a hosted platform, so the list mixes visual builders, CMS platforms, and code-editing tools, and we flag open-core and partly proprietary projects. See our methodology for the full criteria.
Webstudio, Plasmic, Silex, Ycode, Frappe Builder, and Nordcraft are visual builders. Onlook and Frontman edit real code with a visual or AI interface, Builder, Webiny, Drupal, and Vvveb are CMS platforms with varying page-building features, and Grida is a design canvas. Choose by whether you want a Webflow-like designer, a CMS, or a code-first tool.
Webstudio is the closest: a visual builder with full CSS control, a headless CMS connection, and hosting anywhere. Ycode adds a built-in CMS in a Webflow-like builder, and Plasmic and Builder focus on visual building that integrates with a React codebase.
Builder's repository is MIT, but its hosted platform is proprietary. Webiny's Community Edition is MIT, while its Business and Enterprise editions are commercial. Plasmic's platform directory is AGPL-3.0, Webstudio has a proprietary optional animation package, and Frontman's server is AGPL-3.0 with AI Supplementary Terms. Nordcraft is still in the process of going fully open source.
Onlook and Grida are Apache-2.0, and Frappe Builder and Ycode are MIT. Webstudio, Silex, and Vvveb are AGPL-3.0, and Drupal is GPL-2.0-or-later. Plasmic is MIT outside its AGPL-3.0 platform directory.
Webstudio, Silex, Plasmic, Drupal, Vvveb, and Frappe Builder can run on your own servers. Ycode needs your own Supabase and Vercel accounts, and Webiny is designed for AWS serverless infrastructure.
Most projects were updated within days of this update. Onlook's last commit was in August 2026 and Vvveb's in August 2026, so they are slower. Ycode and Nordcraft are young and small.
Webflow is a proprietary hosted platform with site and CMS plan pricing, limits on items and bandwidth, and sites that depend on its hosting. Open-source alternatives let you self-host, own your code and data, avoid plan limits, and connect any backend, at the cost of running hosting yourself and, for many of them, a less polished visual editor.
| Alternative | Type | License | Self-hosted | Best for |
|---|---|---|---|---|
| Onlook | Visual code editor | Apache-2.0 | Desktop app | Next.js projects |
| Webstudio | Visual builder | AGPL-3.0-or-later core | Yes | Webflow-style sites |
| Builder.io | Visual headless CMS | MIT repo / proprietary platform | Partly | Marketing teams |
| Plasmic | Visual builder for React | MIT + AGPL-3.0 (platform) | Yes | React teams |
| Webiny | Serverless CMS | MIT (Community) + commercial | Yes (AWS) | Enterprise content |
| Drupal | CMS | GPL-2.0-or-later | Yes | Complex sites |
| Frappe Builder | Page builder | MIT | Yes | Frappe users |
| Silex | Static site builder | AGPL-3.0 | Yes | Static sites |
| Grida | Design canvas | Apache-2.0 | Yes | Developers and designers |
| Vvveb CMS | CMS with builder | AGPL-3.0-or-later | Yes | Sites with ecommerce |
| Frontman | AI coding agent | Apache-2.0 + AGPL-3.0 server | Yes | Developers |
| Ycode | Visual builder and CMS | MIT | Yes (Supabase and Vercel) | Small sites |
| Nordcraft | Web engine | Apache-2.0 (engine packages) | Partly | Collaborative teams |
Want the closest visual builder to Webflow
Webstudio supports all CSS properties, connects to any headless CMS, and can be hosted anywhere, though its core is AGPL-3.0.
Want a visual builder with a built-in CMS
Ycode is MIT-licensed with a CMS, but self-hosting needs Supabase and Vercel accounts and the project is young.
Want to design visually and keep React code
Plasmic generates production React code with Figma import and data connectors, with an AGPL-3.0 platform directory.
Want to edit a Next.js app visually with AI
Onlook edits real Next.js and Tailwind code with live updates, but it supports no other stack.
Want static sites generated with 11ty
Silex builds static sites visually with dynamic data and self-hosts with Docker or Node.js.
Need a mature CMS for complex content
Drupal offers modular, enterprise-grade content management, with a steeper learning curve.
Want a serverless CMS on AWS
Webiny's MIT Community Edition includes a headless CMS and website builder, while RBAC and multi-tenancy are in paid editions.
Already use the Frappe ecosystem
Frappe Builder is an MIT drag-and-drop page builder on the Frappe Framework.
