    Beautiful Soup

    Beautiful Soup

    Beautiful Soup is a library that makes it easy to scrape information from web pages. It sits atop an HTML or XML parser, providing Pythonic idioms for iterating, searching, and modifying the parse tree. Beautiful Soup's support for Python 2 was discontinued on December 31, 2020: one year after the sunset date for Python 2 itself. From this point onward, new Beautiful Soup development will exclusively target Python 3. The final release of Beautiful Soup 4 to support Python 2 was 4.9.3. Beautiful Soup is licensed under the MIT license, so you can also download the tarball, drop the bs4/ directory into almost any Python application (or into your library path) and start using it immediately.

    Persona

    Persona

    Runtype

    Persona is a VanillaJS Agent UI Library that helps developers create agentic front-end experiences for the web in pure JavaScript. Lightweight, extensible, and WebMCP-native, it runs on any stack and can connect to any SSE backend. Developers can start with a floating launcher in the corner, a copilot docked beside an app, or a full-height assistant that owns the page, changing the launcher configuration without changing the agent or app. Persona is designed for support, docs, sales, onboarding, internal tools, and custom agent experiences where the chat UI becomes another way to operate the application. Through WebMCP, developers can expose page actions, search, carts, bookings, forms, and other tools directly in the browser through a document.modelContext; Persona discovers those tools, asks the user before calling them, and streams the result back into the conversation.
