Revolutionize Your Web Page Capturing with Rollberry's Zero-Install CLI Tool

Transforming Web Page Capturing: The Launch of Rollberry



In an innovative leap for web developers and designers, CORe Inc., an AI connectivity company based in Tokyo, has unveiled its groundbreaking open-source command-line interface (CLI) tool known as Rollberry. This tool allows users to capture high-quality scrolling videos (MP4) of any web page as it is rendered in a real browser, streamlining the way web designs and functionalities are shared.

What is Rollberry?


Every web designer or developer has experienced the challenge of sharing site designs and functionalities through screen recording software, often requiring the tedious task of manually scrolling and managing software installations. Rollberry eliminates all these hassles. By utilizing just a simple command line (npx command) without any software installation, users can efficiently record a video of any specified web page with seamless scrolling.

Key Features of Rollberry


1. Zero Installation Required
Rollberry's standout feature is its remarkable ease of use. With no need to install additional software or applications on your computer, simply input a solitary command into the terminal you regularly work with, and you're ready to go.

2. Captures the ‘Real’ Browser Experience
Rather than recording through hidden systems, Rollberry operates via real browsers (Chromium), ensuring that the videos recorded capture the exact appearance and behavior we experience, free from discrepancies in text or layout.

3. Great for Unpublished and Local Sites
The tool supports the recording of unpublished sites and has a robust automatic retry feature to effectively handle recordings of local environment (localhost) development, allowing devs to capture their work live.

4. Adaptable Screen Sizes
Users can choose their preferred screen sizes, whether for mobile or desktop, and precisely record the web pages accordingly.

5. Effortlessly Hides Obstructive Pop-ups
Rollberry automatically conceals annoying pop-ups, such as cookie consent forms, ensuring a clean recording of the website’s essential content.

6. Compatible with AI Agents
The tool's command simplicity enables it to be utilized directly from AI agents like Claude Code. After developing a web page through AI, a user can instruct the system to save a video of the site's functionality effortlessly, embodying the future of development workflows.

Who Should Use Rollberry?

Those looking to share dynamic functionality and design of their websites easily with team members or clients can greatly benefit from Rollberry.

  • - Developers Utilizing AI
