Description
21st is a development platform designed to help engineers quickly build and deploy AI agents inside their applications. The platform provides a specialized SDK that simplifies the process of defining agent behavior, integrating tools, and connecting AI models. Developers can create agents using familiar technologies such as Next.js, React, TypeScript, Python, and Node.js, making integration straightforward for modern applications. Once an agent is defined, the platform allows it to be deployed with a single command while automatically handling infrastructure requirements. 21st provides sandboxed execution environments through E2B sessions, ensuring that agent operations run securely and independently. The platform includes a ready-to-use chat interface component that can be embedded directly into an app for user interaction. Additional features include token streaming, conversation history, tool execution, and built-in observability for debugging and monitoring. Developers can replay sessions and trace tool calls to better understand how agents behave during execution. The system also supports spend limits, authentication controls, and rate limiting to manage AI usage across users. By combining development tools with managed infrastructure, 21st helps teams launch scalable AI agents without building complex backend systems.
Description
Gummble serves as a comprehensive UI design reference library, boasting over 300,000 authentic app screenshots, more than 21,000 user flows, and a variety of design patterns sourced from over 1,500 launched iOS, Android, and web applications. It is a valuable resource for designers, UX researchers, developers, and product teams, allowing them to search by specific patterns like onboarding processes, paywalls, empty states, and settings, as well as by UI text or complete user flows. Each screen comes with an in-depth design analysis, enabling users to compile references into organized collections. Additionally, its MCP server facilitates interactions with compatible AI assistants and coding tools such as Claude, Cursor, and Codex, enabling them to utilize the library for grounding interface design and implementation in real-world examples. While the free plan provides limited browsing capabilities, the Browse plan unlocks unlimited access to screens, flows, downloads, collections, and MCP features, with the Pro plan further offering Figma export options to enhance workflow efficiency. This multifaceted approach makes Gummble an indispensable tool for anyone involved in UI design.
