Developers, hosting providers, and SaaS founders increasingly want to offer website creation directly inside their platforms. Instead of sending users to a third-party builder, you can embed your own white-label website builder API and instantly unlock new revenue, higher retention, and a better product experience.
The challenge is that most “website builders” don’t actually offer an API. And many that do only provide paid enterprise plans with no way to experiment first.
So we researched platforms that offer real website builder APIs (including free tiers, developer sandboxes, and open-source alternatives). You’ll find a realistic option here for AI-generated websites, a drag-and-drop editor, or full code control.
Let’s explore the best free website builder APIs you can start using today.
What counts as a free website builder API?
To keep this list genuinely helpful, each tool had to meet all of the following:
- Actual API access: REST, GraphQL, SDKs, or programmatic site creation capabilities.
- Embeddable on your own platform: This includes white-label builders, visual editors, and automated website-generation endpoints.
- Free tier, developer sandbox, or open-source license: So you can test and build before committing.
- Some level of branding and UI control: From full white-label dashboards to customizable embedded editors.

Free vs paid website builder APIs: which one do you need?
Choosing between a free and paid website builder API really comes down to what you want your platform to deliver and how much of the infrastructure you want to maintain yourself.
If your goal is to offer users a complete website creation experience without building any backend, a hosted API is almost always the right choice. This gives you։
- The fastest path to launching a fully functional site builder inside your SaaS product, marketplace, or hosting environment.
- Instant site deployment, built-in security, multi-site support, white-labeling, and ready-to-use editing tools.
And this is exactly where 10Web stands out as the best option. Instead of piecing together a visual editor, a hosting layer, a provisioning system, and an AI generator, 10Web gives you everything through a unified API and simple website builder API documentation.
You can generate complete websites from a simple prompt, provision WordPress instantly, manage clients under your own brand, and offer a modern AI editing experience; everything backed by managed hosting and a fully white-label dashboard.
For teams that prefer to stay closer to the code, hybrid or open-source builders have their value, but they require engineering resources, custom hosting, and ongoing maintenance. These approaches offer flexibility, but not the speed, scalability, or automation that most platforms need when they want to deliver polished websites to users at scale.
In simple terms:
- If you want the fastest, most scalable way to offer instant websites under your own brand, choose a hosted API.
- If you want a complete, production-ready solution without assembling your own infrastructure, 10Web is the best and most fully featured option to build on.

FAQ
What is a website builder API?
A website builder API allows you to embed website creation features directly into your own platforms. Instead of relying on a standalone website builder, it enables programmatic site generation, editing, and deployment through REST, GraphQL, or SDK-based endpoints. This makes it possible to offer website creation inside SaaS products, hosting dashboards, and marketplaces.
What makes a website builder API “free”?
A free website builder API offers either a free tier, a developer sandbox, or an open-source license that lets you experiment without paying upfront. These options allow you to build, test, and integrate the API before committing to a paid plan or production usage. Free doesn’t always mean unlimited use — it typically applies to development stages or small projects.
Can I embed website creation into my SaaS?
Yes. The tools listed in the article allow you to embed a website builder directly into your SaaS platform. Depending on the provider, you can offer AI-generated websites, drag-and-drop editors, or custom-coded experiences, all under your own brand.
How do I choose between self-hosted vs hosted builder API?
Choose a hosted API if you want the fastest path to launching a complete website builder without handling infrastructure, hosting, or security yourself. A self-hosted or open-source option makes more sense if you want total control over the code and user experience, but it requires significantly more engineering work. The right choice depends on whether you prioritize speed and scalability or customization and ownership.
How does the 10Web Website Builder API compare to other options?
10Web stands out because it offers AI website generation, automated WordPress provisioning, managed hosting, and a fully white-label dashboard; all from a single API. While other tools either provide visual editing or open-source flexibility, 10Web delivers an end-to-end solution that eliminates the need to build your own hosting, templates, or infrastructure. It’s the most complete option for platforms that want instant, scalable website creation under their own brand.
