Firebase Genkit
An open-source framework by Google that helps developers easily build, test, and deploy AI-powered features into their applications.
What is Firebase Genkit?
Genkit is an open-source AI integration framework designed for app developers. It simplifies the process of adding advanced AI capabilities—like custom content generation, semantic search, and autonomous agents—to existing Node.js or Go applications.
Key Features
- Model Agnostic: While highly optimized for Gemini, Genkit supports a plugin architecture allowing you to easily swap out underlying LLMs, vector stores, and evaluators.
- Developer UI: Comes with a powerful local Developer UI that lets you run, trace, and debug complex AI flows step-by-step before deploying them to production.
- Production Ready: Seamlessly integrates with Google Cloud and Firebase ecosystem services for authentication, scalable deployment, and performance monitoring.
💰 Pricing
Firebase Genkit is free and open-source. You pay only for the underlying services you use — LLM API calls (Gemini, OpenAI, etc.), Firebase hosting, and Google Cloud compute. There is no Genkit-specific licensing fee.
