[Genkit](https://genkit.dev) is an open-source framework for building full-stack AI-powered applications, built and used in production by Google's Firebase. It 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)**: Early development with core functionality
It offers a unified interface for integrating AI models from providers like [Google](https://genkit.dev/docs/plugins/google-genai), [OpenAI](https://genkit.dev/docs/plugins/openai), [Anthropic](https://thefireco.github.io/genkit-plugins/docs/plugins/genkitx-anthropic), [Ollama](https://genkit.dev/docs/plugins/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.
Get started with just a few lines of code:
```ts
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?'
});
```

## How does it work?
Genkit simplifies AI integration with an open-source SDK and unified APIs that
work across various model providers and programming languages. It abstracts away complexity so you can focus on delivering great user experiences.
Some key features offered by Genkit include:
* [Text and image generation](https://genkit.dev/docs/models)
* [Type-safe, structured data generation](https://genkit.dev/docs/models#structured-output)
* [Tool calling](https://genkit.dev/docs/tool-calling)
* [Prompt templating](https://genkit.dev/docs/dotprompt)
* [Persisted chat interfaces](https://genkit.dev/docs/chat)
* [AI workflows](https://genkit.dev/docs/flows)
* [AI-powered data retrieval (RAG)](https://genkit.dev/docs/rag)
Genkit is designed for server-side deployment in multiple language environments, and also provides seamless client-side integration through dedicated helpers and [client SDKs](https://genkit.dev/docs/firebase).
## Implementation path

<tr>
<td><span>1</span></td>
<td>Choose your language and model provider</td>
<td>Select the Genkit SDK for your preferred language (JavaScript/TypeScript, Go, or Python (Alpha)). Choose a model provider like <a href="https://genkit.dev/docs/plugins/google-genai">Google Gemini</a> or Anthropic, and get an API key. Some providers, like <a href="https://genkit.dev/docs/plugins/vertex-ai">Vertex AI</a>, may rely on a different means of authentication.</td>
</tr>
<tr>

## Development tools
Genkit provides a CLI and a local UI to streamline your AI development workflow.
### CLI
The Genkit CLI includes commands for running and evaluating your Genkit functions (flows) and collecting telemetry and logs.
- **Install:** `npm install -g genkit-cli`
- **Run a command, wrapped with telemetry, a interactive developer UI, etc:** `genkit start -- <command to run your code>`
### Developer UI
The Genkit developer UI is a local interface for testing, debugging, and iterating on your AI application.
Key features:
- **Run:** Execute and experiment with Genkit flows, prompts, queries, and more in dedicated playgrounds.
- **Inspect:** Analyze detailed traces of past executions, including step-by-step breakdowns of complex flows.
- **Evaluate:** Review the results of evaluations run against your flows, including performance metrics and links to relevant traces.
