VibeKit

What is VibeKit?

VibeKit is an open-source (MIT licensed) Software Development Kit (SDK) designed for developers and teams who want to integrate powerful AI coding agents like OpenAI's Codex or Anthropic's Claude directly into their applications or internal tools. Its core value proposition lies in providing a secure and private sandbox environment for executing the code generated by these AI models, mitigating security risks. It allows for customization of the execution environment, installation of packages, and supports various sandbox providers (e.g., E2B, Daytona, Modal, Fly.io), making it flexible for different deployment and security needs.

How to use VibeKit

Users interact with VibeKit by installing its SDK via npm (`npm i @vibe-kit/sdk`). Developers then configure the SDK with their chosen AI agent (e.g., Codex) and a compatible sandbox provider. They can use the SDK's methods, such as `generateCode`, to send prompts to the AI agent and receive generated code or answers, with support for streaming output. The SDK itself is open-source and MIT licensed, implying no direct cost for the SDK, but users would likely incur costs from their chosen AI models and sandbox providers.
