Build AI Applications with Genkit

Genkit is an open-source framework for building full-stack AI-powered applications, built and used in production by Google’s Firebase. It provides a unified interface for integrating AI models from providers like Google, OpenAI, Anthropic, Ollama, and more. Rapidly build and deploy production-ready chatbots, automations, and recommendation systems using streamlined APIs for multimodal content, structured outputs, tool calling, and agentic workflows.

Multi-Language Support

Genkit provides SDKs for multiple programming languages with varying levels of stability:

JavaScript/TypeScript

Production-ready with full feature support

Go

Production-ready with full feature support

Python

Alpha release with core functionality

Get Started in Seconds

Genkit makes AI integration simple with just a few lines of code:
import { genkit } from 'genkit';
import { googleAI } from '@genkit-ai/google-genai';

const ai = genkit({ plugins: [googleAI()] });

const { text } = await ai.generate({
    model: googleAI.model('gemini-2.5-flash'),
    prompt: 'Why is Firebase awesome?'
});

Key Capabilities

Use a unified interface to integrate with hundreds of models from providers like Google, OpenAI, Anthropic, Ollama, and more. Explore, compare, and use the best models for your needs.
Use streamlined APIs to build AI features with structured output, agentic tool calling, context-aware generation, multi-modal input/output, and more. Genkit handles the complexity of AI development, so you can build and iterate faster.
Integrate seamlessly with frameworks and platforms including Next.js, React, Angular, iOS, Android, using purpose-built client SDKs and helpers.
Build with the language that best fits your project. Genkit provides SDKs for JavaScript/TypeScript, Go, and Python (Alpha) with consistent APIs and capabilities across all supported languages.
Deploy AI logic to any environment that supports your chosen programming language, such as Cloud Functions for Firebase, Google Cloud Run, or third-party platforms, with or without Google services.
Accelerate AI development with a purpose-built, local CLI and Developer UI. Test prompts and flows against individual inputs or datasets, compare outputs from different models, debug with detailed execution traces, and use immediate visual feedback to iterate rapidly on prompts.
Ship AI features with confidence using comprehensive production monitoring. Track model performance, request volumes, latency, and error rates in a purpose-built dashboard. Identify issues quickly with detailed observability metrics.

Core Features

Genkit simplifies AI integration with an open-source SDK and unified APIs that work across various model providers and programming languages:

Implementation Path

1

Choose your language and model provider

Select the Genkit SDK for your preferred language (JavaScript/TypeScript, Go, or Python). Choose a model provider like Google Gemini or Anthropic, and get an API key. Some providers, like Vertex AI, may rely on a different means of authentication.
2

Install the SDK and initialize

Install the Genkit SDK, model-provider package of your choice, and the Genkit CLI. Import the Genkit and provider packages and initialize Genkit with the provider API key.
3

Write and test AI features

Use the Genkit SDK to build AI features for your use case, from basic text generation to complex multi-step workflows and agents. Use the CLI and Developer UI to help you rapidly test and iterate.
4

Deploy and monitor

Deploy your AI features to Firebase, Google Cloud Run, or any environment that supports your chosen programming language. Integrate them into your app, and monitor them in production in the Firebase console.
