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

Supernova streamlines the entire lifecycle of your design system in a single platform, allowing your team to retain their preferred tools and avoid the hassle of maintaining custom workflows and integrations. By automating processes to align with your existing work methods, you can empower designers, developers, product owners, and stakeholders to utilize their favorite tools while contributing in their own unique ways. This flexibility enables everyone to work in the manner they are most comfortable with, enhancing overall productivity. Comprehensive documentation is vital for widespread adoption of your design system, and Supernova equips you with advanced tools to build a robust resource that unifies your teams. You can enrich your design system with added layers of data derived from Figma imports, including descriptions, comments, custom properties, and statuses. Furthermore, design system modifications in Figma, updates to documentation, and open pull requests can all be published automatically, eliminating the need for manual intervention. By adhering to the predefined rules you establish, Supernova ensures a seamless workflow that adapts to your team's dynamic needs. Ultimately, this integrated approach fosters collaboration and innovation across all facets of the design process.
