SDK to integrate an IA Claude Code agent into your application
21st provides a complete infrastructure for deploying CLI-based AI agents to production. It includes sandboxing, authentication, a UI, and observability, enabling developers to go from building an agent in a weekend to deploying it in production in months. The platform handles containers, secret injection, authentication, logging, tracing, tenant isolation, and chat UI components. Development is done in TypeScript, with simplified deployment via the CLI. Agents run in isolated sandbox environments (E2B with gVisor) that boot in seconds. Secure credential management (API keys, environment variables) is handled and injected at runtime. React UI components are provided out-of-the-box. Observability covers cost per session, latency, errors, and token usage. Agent templates are available for various use cases like support, research, or web scraping agents. The pricing model is pay-as-you-go with a custom option for teams requiring on-premise infrastructure or advanced security and management features.
For solopreneurs, SDK 21st Agents enables the creation of an AI-powered customer support chatbot. This allows for instant responses to common inquiries, freeing up the solopreneur's time for core business activities. For example, a freelance web designer can use it to answer questions about pricing and service packages 24/7.
For university students, SDK 21st Agents enables the development of a custom AI notebook assistant for note-taking and knowledge retrieval. This tool can help students organize lecture notes and quickly find information for assignments. For instance, a computer science student can build an agent that summarizes complex coding concepts from their notes.
For software developers, SDK 21st Agents enables the integration of an AI agent to query internal documentation or knowledge bases. This provides quick answers to technical questions for team members. For example, a developer can create an agent that answers questions about API usage based on the company's internal documentation.
For small business owners, SDK 21st Agents enables the creation of an AI agent to qualify incoming leads.

21st Agents offers a 'Usage' tier that is pay-as-you-go, suitable for developers shipping their first agents. This tier includes features like unlimited agents, sandboxed runtimes, and a chat UI. A 'Scale' tier is available for teams running agents on their own infrastructure with custom pricing.
