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
T3 Code is a minimal web GUI for coding agents like Codex, built to give agents a better place to work than a terminal. It is free, open source, fast, and designed so you can install it, plug in the harness you already pay for, and let your agents get to work. It provides a clean, modern interface for interacting with AI coding assistants through both web and desktop applications, with session management, persistent state, thread management, and real-time collaboration. Developers can interact with coding agents through an intuitive chat-based interface, manage coding sessions across projects, track changes with built-in git integration and checkpointing, and control access through Full Access and Supervised runtime modes. T3 Code is built to be modifiable, customizable, and forkable, with an MIT license, commercial-friendly use, TypeScript, strict end-to-end typing, and a monorepo that includes desktop, web, server, and harnesses.
