README
The AI-native Web OS for building, running, and owning websites and business applications.
Kooboo is one integrated platform for creating websites, online stores, and business applications.
AI website creation, visual editing, content management, databases, ecommerce, email, analytics, hosting, development, and deployment all work together in one portable system.
Build a real website in minutes. Edit every part. Run it anywhere. Keep control of the result.
Download the latest release · Start with Kooboo Cloud · Documentation · Report an issue
Free to use. Not open source.
Anyone can download and use Kooboo without a time limit. Public releases contain compiled packages. Controlled source access is available separately to approved partners.
Getting started
You can run Kooboo on your own computer or server, or use the hosted Kooboo Cloud service.
Run Kooboo locally
- Open the latest Kooboo release.
- Find the package for Windows, macOS, or Linux.
- Download and extract the package if required.
- Start Kooboo:
- Windows: double-click the Kooboo application.
- macOS: open the Kooboo application from the downloaded package.
- Linux: run the Kooboo executable from the terminal or as a service
- Open the local address displayed by Kooboo in your browser.
For a production Linux server, Kooboo can be configured as a system service so that it starts automatically and restarts after a server reboot.
Use Kooboo Cloud for free
If you do not want to install anything, you can use the hosted Kooboo Cloud service.
Create an account, create a website, and begin building directly in your browser.
Development
Kooboo supports different development styles—from AI-assisted creation to declarative HTML and full server-side scripting.
You can choose the simplest method for each task and combine all three inside the same website.
Hello, world
After starting Kooboo:
- Create a new website.
- Open Pages.
- Create a new page.
- Add the following HTML:
<h1>Hello, world!</h1>
<p>This page is running in Kooboo.</p>
- Save the page and open its URL.
You now have a working Kooboo website.
2. Build with Native AI
Kooboo Native AI works directly with the website’s Pages, Layouts, Views, content, databases, APIs, scripts, media, configuration, and history.
It can build a website, run it, inspect the result, diagnose problems, make changes, and validate the finished site.
Build → Run → Observe → Diagnose → Modify → Validate → Publish → Improve

Built by AI. Tested by AI. Run by AI. Owned by you.
2. Build fully dynamic websites using HTML
Kooboo can query structured content and render dynamic pages directly from an HTML template.
The following example loads every item from BlogFolder and displays its title and summary:
<k-data>
<query
as="blogs"
source="content"
resource="BlogFolder"
action="list"
export>
</query>
</k-data>
<div k-for="blog in blogs">
<h2 k-content="blog.title"></h2>
<p k-content="blog.summary"></p>
</div>
There is no separate controller or external template engine to configure. The data query, loop, and content binding are declared directly in the page.
3. Use JavaScript with KScript
KScript is standard JavaScript with the additional k.* namespace for accessing Kooboo functions.
You can use normal JavaScript syntax, libraries, objects, arrays, and programming patterns. Through the k.* namespace, your code can work directly with Kooboo content, databases, APIs, users, requests, configuration, email, and other platform services.
This example loads blog content using server-side JavaScript:
<script env="server">
var blogs = k.content.BlogFolder.all();
</script>
<div k-for="blog in blogs">
<h2 k-content="blog.title"></h2>
<p k-content="blog.summary"></p>
</div>
JavaScript development is included in the free version of Kooboo cloud. TypeScript development is available in paid Plans.
Key features
Native AI
Kooboo Native AI works inside the website platform rather than operating as a separate chat box.
It can work with Pages, Layouts, Views, content, databases, APIs, ecommerce, scripts, media, configuration, analytics, and website history.
The AI can build the website, run it, inspect the result, diagnose problems, make changes, validate those changes, and continue improving the site.
Build → Run → Observe → Diagnose → Modify → Validate → Publish → Improve

High performance
Kooboo uses one integrated runtime for domain resolution, routing, data access, server-side rendering, caching, and network delivery.
There is no need to connect and operate a large collection of separate services just to run a dynamic website.
In a published public-Internet pressure test, one Kooboo process hosted:
- 5,000 independently addressable dynamic websites
- 90,000 complete HTTPS requests
- 89,969 correct first-attempt responses
- 99.97% first-attempt success
- A server with only 2 vCPUs and 4 GB of memory
Read the complete 5,000-site benchmark
The benchmark report includes the hardware, workload, latency distribution, failures, CPU and memory records, request-level data, test client, and reproduction packages.
Do not benchmark the brochure. Download Kooboo and benchmark the product.
Portal and Marketplace
The Kooboo portal gives you one place to create, import, organize, edit, and operate websites and applications.
The Kooboo Marketplace provides complete website and application packages—not only visual themes.
A package can include:
- Pages, Layouts, and Views
- Content and data
- HTML, CSS, and JavaScript
- Images and other media
- Routes and configuration
- APIs and application logic
- Ecommerce and business features
Install a package, inspect how it works, customize every part, and continue running it in your own Kooboo environment.
