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

Session Orchestrator is a free, MIT-licensed workflow plugin for Claude Code, Codex CLI, Cursor and Pi. It reads repository context and issues, helps plan work, coordinates implementation in checked waves, and records verification results and remaining tasks for the next session. Workflows cover session startup, planning, execution, review and close-out. It runs locally with Node.js 24 or later. Enforcement varies by host: Codex file-scope and destructive-command rules are instructions rather than enforced hooks. Source code and documentation are available on GitHub.
