Stars: 461

Motia is an AI agent framework designed for software engineers to create, test, and deploy production-ready AI agents quickly. It provides a code-first approach, allowing developers to write agent logic in familiar languages and visualize execution in real-time. With Motia, developers can focus on business logic rather than infrastructure, offering zero infrastructure headaches, multi-language support, composable steps, built-in observability, instant APIs, and full control over AI logic. Ideal for building sophisticated agents and intelligent automations, Motia's event-driven architecture and modular steps enable the creation of GenAI-powered workflows, decision-making systems, and data processing pipelines.
README:
Motia lets developers create, test, and deploy production-ready AI agents in minutes, in a framework that will feel familar to software engineering teams. Write your agent logic in the languages and package you know and love. Visualize execution in real-time, and deploy without DevOps headaches.
Building production-grade AI agents is tough. You're usually forced to choose:
- No-code/Low-code tools: Quick to start, but can't handle real-world complexity at scale.
- Fully-agentic Frameworks: Great for creative tasks but difficult to manage and control consistent outputs
- ML-focused Frameworks: Designed for model training and optimization, not for orchestrating complex business workflows.
- Custom code: Quickly becomes unmanageable as agents grow in complexity and span across teams.
Motia gives you full, code-first control of your agents and automations with the simplicity of a visual interface, letting you focus on what truly matters: your business logic, not your infrastructure.
Motia is built for developers who want to build agentic and intelligent, event-driven systems rapidly and reliably. Here's what makes Motia the ideal choice:
- π Zero Infrastructure Headaches - No Kubernetes expertise required. Deploy agents with a single command.
- π» True Code-First Development - Write agent logic in familiar languages, not proprietary DSLs.
- π Unique Multi-Language Support - Mix Python for ML, TypeScript for type safety, and Ruby for APIs in the same agent.
- 𧩠Composable Steps with Runtime Validation - Build agents from modular, reusable components with automatic input/output validation.
- π Built-in Observability - Debug agent behavior with visual execution graphs and real-time logging.
- β‘οΈ Instant APIs & Webhooks - Expose agent functionality via HTTP endpoints without extra code.
- π§ Full Control Over AI Logic - Use any LLM, vector store, or reasoning pattern without restrictions.
- π€ΈββοΈ Flexible Control - Easilty switch between agentic and deterministic control within the same flow.
Motia's event-driven architecture and modular steps are perfectly suited for building sophisticated agents and intelligent automations. Whether you're creating GenAI-powered workflows, complex decision-making systems, or data processing pipelines, Motia provides the ideal foundation.
- Create Agent Components as Steps: Encapsulate agent logic, tool integrations, and decision-making processes within individual steps, leveraging the rich ecosystems of JavaScript, Python, and Ruby.
- Orchestrate Agent Interactions with Flows: Design complex agentic workflows by connecting steps to create sophisticated sequences of actions and reactions, easily integrating steps written in different languages.
- Test and Evaluate Agent Behavior Visually: The Motia Workbench provides real-time visualization and testing tools to observe and refine your agents' behavior and ensure they perform as expected, regardless of the underlying step language.
- Iterate and Evolve Agents Rapidly: Motia's modularity and observability make it easy to iterate on agent logic, experiment with different approaches, and continuously improve your intelligent systems, taking advantage of the strengths of each supported language.
The Motia Workbench is your browser-based development environment.
- Interactive Flow Visualization: See your steps connected in a dynamic, visual graph. Understand event flow and step interactions at a glance.
- Real-time Testing: Trigger API endpoints and emit events directly from the UI to test your flows and agents in real-time.
- Live Log Streaming: Monitor logs in real-time within the Workbench, making debugging and observing execution a breeze.
- Step Customization: Create custom UI components for your steps to enhance visualization and tailor the Workbench to your workflows.
Ready to get started in minutes? Follow these simple steps using pnpm and the automated project creation:
-
Create a new project using the Motia CLI:
npx motia create -n my-first-agent
(Replace
my-first-agent
with your desired project name)This command will:
- Create a new folder
my-first-agent
- Set up a basic Motia project with example steps
- Install dependencies using pnpm
- Create a new folder
-
Navigate into your new project directory:
cd my-first-agent
-
Start the Motia development server:
pnpm run dev
-
Open the Motia Workbench in your browser (usually
http://localhost:3000
). You should see a pre-built flow named "default" with example steps visualized. -
Test an example API Step: In your terminal, use
curl
to trigger the example API endpoint (often/default
in the default template):curl -X POST http://localhost:3000/default \ -H "Content-Type: application/json" \ -d '{}'
Alternatively, use the Motia CLI to emit an event (for event-based steps in the template):
npx motia emit --topic test-state --message '{}'
Check the Workbench logs β you should see logs indicating the step execution and event flow!
Congratulations! You've just created and run your first Motia workflow using the automated project setup.
- Configure a simple to emit/subscribe, assign to a flow and inculde runtime validation
- Define a function to handle when the step is triggered
- Import any package
import { OpenAI } from 'openai';
import { z } from 'zod';
import type { EventConfig, StepHandler } from 'motia';
const openai = new OpenAI({
apiKey: process.env.OPENAI_API_KEY,

};
export const handler: StepHandler<typeof config> = async (inputData, context) => {
const { subject, body, from } = inputData;
const { emit, logger } = context;
const sentimentResponse = await openai.chat.completions.create({
model: "gpt-4o",
messages: [{ role: "user", content: `Analyze the sentiment of the following text: ${body}` }],
});
const sentiment = sentimentResponse.choices[0].message.content;
logger.info('[EmailAutoReply] Sentiment analysis', { sentiment });
emit({
type: 'email.send',
data: { from, subject, body, sentiment },
});
};
