About

21st is a developer platform that provides the fastest way to add AI agents directly into applications. The platform offers an SDK that allows developers to define, deploy, and run AI agents with minimal infrastructure setup. Developers can integrate agents using popular frameworks such as Next.js, React, TypeScript, Python, and Node.js. 21st includes built-in features like chat interfaces, session history, tool execution, memory, and real-time streaming responses. The platform also manages backend components such as sandboxed execution environments, authentication, rate limits, and observability. With support for Claude Code and Codex runtimes, developers can build agents that interact with tools, files, and APIs securely. By handling infrastructure and deployment automatically, 21st enables teams to launch production-ready AI agents quickly.

About

Volca is a comprehensive SaaS boilerplate and starter kit designed to accelerate the development and deployment of SaaS applications. It provides a monorepo that includes a high-performance static landing page, a React dashboard, and a Node.js REST API. The landing page is pre-rendered as static HTML files, ensuring quick load times and improved search engine rankings, and is built with React and TypeScript. The dashboard serves as the primary interface for users, offering features such as user registration, subscription management, and team collaboration, allowing users to create projects and invite team members. The backend API is built with Node.js and TypeScript, operating on a serverless architecture that is cost-effective, secure, and performant.
