So what is it?

Firebase Genkit is a framework that helps developers add AI-powered features to their applications. Instead of wrestling with the plumbing of different AI models, databases, and cloud deployment, developers get a single toolkit to build, test, and launch features like chatbots, content generators, or smart search. It is designed to feel familiar to developers who already know standard coding patterns, minimizing the number of entirely new concepts they need to learn. At a high level, it works by providing a unified interface for interacting with various AI models from Google and other providers. Developers can write prompts in dedicated template files, ask the AI to return data in structured formats that their app can easily use, and give the AI custom tools to fetch information from a database. It also includes a local developer interface where you can prototype and test your AI features, run evaluations against test questions, and view step-by-step traces of how the AI arrived at its output. This project is built for app developers who want to make their software smarter without becoming AI specialists. For example, a developer building a customer support app could use it to create an AI agent that searches the company's knowledge base and answers user questions. A startup founder building a scheduling app could use it to generate natural language summaries of daily agendas. It is particularly useful for teams already building on Google's ecosystem, since it offers straightforward deployment to Firebase and Google Cloud, along with integrations for their specific databases and monitoring tools. The framework is free and open source, currently available for TypeScript (Node.js) with Go support in active development. A notable aspect of its design is its plugin system, which lets developers tap into pre-built components from Google and the community, or easily write their own. Since the project is still in beta, developers should expect that the underlying code might change in ways that require updates to their apps down the road.

Copy-paste prompts

Prompt 1
Using the Firebase Genkit framework in TypeScript, write code for an AI feature that takes a user's text question, searches a local array of documents for context, and returns a structured JSON answer with a confidence score.
Prompt 2
Create a Genkit prompt template file that instructs an AI model to summarize a list of daily calendar events into a short natural language agenda, returning the result as a typed object.
Prompt 3
Show me how to set up a basic Genkit flow with a custom tool that fetches user profile data from a mock database, then use the local developer UI to test and view the trace of that flow.
Prompt 4
Write a Genkit plugin that connects to a custom data source, following the patterns used by existing Google and community plugins.
