A GrapesJS alternative for magazine-style pages
GrapesJS and ContentBox.js are both JavaScript page builders you add to your own website or app, so your users can design pages visually. They start from different places. GrapesJS is an open-source framework for building your own web builder, with a ready-made Studio SDK on paid plans. ContentBox.js is a finished page builder, made for elegant, editorial design.
Edit your content while it moves
Pages today are animated and interactive: headlines that fly in, photos that move in formations as you scroll, tabs and sliders. Most editors have to work around that code. They switch to a separate edit mode, stop the animation, or send you into complex settings or the code behind it.
In ContentBox.js you view and edit in the same place, and the animations keep running while you edit:
- Click into a headline while it moves across the screen, and type.
- Replace one photo in a series of images flying in formation. The formation keeps working.
- Edit the text inside a tab or a slider directly, without opening any settings.
This works because ContentBox.js separates what you edit from what runs by itself. Your text, images, links and layout are yours to change. The animations and interactive effects come with the design, made by a developer or by AI, and you never touch their code.
A simple test for any editor: can you edit animated text or images while the animation runs, and does everything still work afterwards? Try it in the ContentBox.js demo.
Why not just ask AI to change it?
AI can build a page, and it can change one too. But a published page needs small changes all the time: a word, a price, a photo, a link. Asking AI for each one is slow, every request rewrites code that was working, and your clients can't do it themselves. An editor lets the people who own the content change it directly, in seconds. AI stays a helper, not something you depend on.
The short answer
Choose ContentBox.js if
- you want a page builder that works out of the box, with 250+ designed layouts;

Built for editorial design
Most builders aim at landing pages and utility layouts. ContentBox.js is made for storytelling, branding and portfolios: full-width sections like a print magazine, generous whitespace, bold headlines and oversized text. Rows and columns make intentionally asymmetric layouts easy, without the chaos of free nesting. When a design needs it, a Canvas section lets you place blocks freely, so grid and gridless sit on the same page.
Complete out of the box
The open-source GrapesJS core gives you the building parts; the layouts, the look and much of the editing experience are yours to create, or you subscribe to its Studio SDK. ContentBox.js comes with over 250 designed layouts, section templates, editorial typography, plugins such as sliders and galleries, and a no-code animation builder with scroll scrubbing and section pinning, effects that normally take hand-written GSAP code. You add it to your app, and your users can start designing.
A generous license, paid once
ContentBox.js is a one-time purchase with a No Limits License:
- Every package lets you use it in an unlimited number of websites, yours or your clients', personal or business.
- Pro lets you offer it in your own SaaS product, to unlimited users.
- Super covers up to three SaaS products and includes the source code.
It runs on your own server, so there are no per-load, per-session, per-user or per-domain fees as your product grows. AI features use your own OpenRouter or Fal.ai account, so you pay the AI provider directly, at their price. See prices and the packages explained.
