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

Merge technology is a revolutionary way to speed up product development. UI designers and developers can create consistent interfaces with the same building blocks. Create prototypes that feel like the final product. Use our design tool to get creative or use hundreds of pre-built UI elements. Integrate with Storybook, Git repo or NPM package to access code components directly from your website, app, or design system. You can design with the exact same UI components that developers use to build products. You don't need to know any coding skills - drag and drop the elements. Design inclusive products that conform to WCAG standards. Your prototypes can be tested with built-in features such as the Contrast Checker or Color Blindness Simulator. Your prototypes will be able to replicate the final product experience during usability testing thanks to Auto Layout, States, Variables and Conditional Interactions.
