Pagesource is a command-line tool designed to capture and dump the runtime sources of a website, providing a more accurate representation of the site’s structure for local language model (LLM) context. Unlike the traditional “Save As” feature in browsers that flattens the webpage into a single HTML file, Pagesource preserves the actual file structure, including separate JavaScript modules, CSS files, and lazy-loaded resources. Built on Playwright, it allows developers to access all dynamically loaded JS modules and maintain the original directory structure, making it particularly useful for web developers who need to replicate or analyze website components effectively. This matters because it enhances the ability to work with LLMs by providing them with a more detailed and accurate context of web resources.
Pagesource is a command-line interface (CLI) tool designed to enhance the workflow of web developers, particularly those who work with local language models (LLMs). Traditional methods like the browser’s “Save As” function often result in a single, flattened HTML file that lacks the detailed file structure required for effective LLM input. Pagesource addresses this by capturing the runtime sources of a website, providing a more accurate representation of what the browser loads and executes. This includes separate JavaScript and CSS files, as well as dynamically loaded modules, offering a comprehensive view of the website’s architecture.
The tool leverages Playwright, a powerful automation library, to achieve its functionality. By using Playwright, Pagesource can capture all JavaScript modules, including those loaded dynamically, and separate CSS files. It also maintains the actual directory structure of the website, which is crucial for developers who need to understand how different components interact within the site. Additionally, Pagesource can capture lazy-loaded resources that are typically loaded after the initial page load, providing a complete picture of the website’s runtime environment.
For web developers, especially those interested in replicating or learning from existing websites, Pagesource is invaluable. It allows developers to dissect a website’s structure and functionality in a way that is not possible with traditional methods. By providing the actual runtime sources, developers can prompt LLMs with more accurate and context-rich data, leading to better insights and more effective development processes. This can be particularly useful when trying to replicate design elements or understand complex interactions within a site.
In the broader context of web development, tools like Pagesource are becoming increasingly important as developers seek to harness the power of LLMs for tasks such as code generation, debugging, and learning. By providing a way to capture and analyze the runtime sources of a website, Pagesource enables developers to work more efficiently and creatively. This matters because it empowers developers to push the boundaries of what is possible with web technologies, ultimately leading to more innovative and user-friendly web experiences. As the use of LLMs continues to grow, tools that facilitate their integration into the development workflow will be essential.

Utilizing Pagesource to preserve the complete file structure of a website offers a significant advantage for developers aiming to work with LLMs, as it ensures that all dynamic components are accurately captured. This capability is crucial for detailed analysis, especially when dealing with complex sites that rely heavily on JavaScript. How does Pagesource handle sites with extensive use of client-side rendering frameworks like React or Vue?
Pagesource effectively captures sites using client-side rendering frameworks like React or Vue by leveraging Playwright to execute JavaScript and load all dynamic components. This ensures that the runtime sources, including dynamically loaded modules, are preserved accurately. For more detailed insights, you might want to check the original article linked in the post.
