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
WebContainers, developed by StackBlitz, are a browser-based runtime environment that enables the execution of Node.js applications and operating system commands directly within a web browser tab. This technology allows developers to build instant, interactive coding experiences, from tutorials to full-fledged integrated development environments, without the need for local setups or cloud-based virtual machines. By running entirely client-side, WebContainers offer unmatched user experiences with zero latency, offline capabilities, and enhanced security, as they eliminate the risks associated with server-side code execution. They support native Node.js toolchains, including npm, pnpm, and yarn, and are compatible with major modern frameworks. Additionally, WebContainers facilitate the running of WebAssembly (Wasm) out of the box, allowing for the porting of various languages and frameworks to the browser environment.
