This is the repo for Vue 2. For Vue 3, go to https://github.com/vuejs/core
Pros of Vue
- Mature, widely-adopted framework with extensive ecosystem and community support
- Comprehensive documentation and learning resources
- Flexible and scalable for both small and large applications
Cons of Vue
- Steeper learning curve for beginners compared to Motia
- Potentially more complex setup and configuration
- Larger bundle size, which may impact initial load times
Code Comparison
Vue component:
<template>
<div>{{ message }}</div>
</template>
<script>
export default {
data() {
return {
message: 'Hello, Vue!'
}
}
}
</script>
Motia component:
import { Component } from 'motia';
class HelloWorld extends Component {
render() {
return `<div>${this.message}</div>`;
}
message = 'Hello, Motia!';
}
While both frameworks allow for component-based development, Vue uses a template-based approach with a more structured component definition. Motia, on the other hand, employs a class-based syntax with a simpler render method. Vue's template syntax may be more intuitive for some developers, while Motia's approach might appeal to those who prefer a more JavaScript-centric style.

Pros of Angular
- Mature, widely-adopted framework with extensive documentation and community support
- Comprehensive ecosystem with built-in tools for routing, forms, and HTTP requests
- Strong TypeScript integration for improved type checking and tooling
Cons of Angular
- Steeper learning curve due to its complexity and size
- Heavier bundle size compared to lighter alternatives
- More opinionated structure, which may limit flexibility for some projects
Code Comparison
Angular component:
@Component({
selector: 'app-root',
template: '<h1>{{title}}</h1>'
})
export class AppComponent {
title = 'Hello Angular';
}
Motia component (hypothetical, as no code is available in the repository):
// No code available for comparison
Summary
Angular is a full-featured, enterprise-grade framework with a large ecosystem and strong TypeScript support. It offers comprehensive tools but comes with a steeper learning curve and larger bundle size. Motia, on the other hand, appears to be a smaller, less established project with limited public information or code available for comparison. The choice between the two would depend on project requirements, team expertise, and desired level of framework support and features.

Code Comparison
Svelte component:
<script>
let count = 0;
function increment() {
count += 1;
}
</script>
<button on:click={increment}>
Clicks: {count}
</button>
Motia component (hypothetical, as Motia's exact syntax is not publicly available):
import { Component } from 'motia';
class Counter extends Component {
state = { count: 0 };
increment() {
this.setState({ count: this.state.count + 1 });
}
render() {
return `
<button onclick="this.increment()">
Clicks: ${this.state.count}
</button>
`;
}
}

import { h, render } from 'preact';
const App = () => <h1>Hello World!</h1>;
render(<App />, document.body);
Motia:
import { createComponent } from 'motia';
const App = createComponent({
render: () => '<h1>Hello World!</h1>'
});
App.mount(document.body);
Key Differences
- Preact uses JSX syntax, while Motia uses string templates
- Preact's API is closer to React, Motia has a unique approach
- Preact offers more features and flexibility, Motia focuses on simplicity
Use Cases
- Preact: Web applications, especially those migrating from React
- Motia: Mobile-first applications, projects prioritizing simplicity
Community and Ecosystem

Pros of Alpine
- More mature and widely adopted project with a larger community
- Extensive documentation and examples available
- Lighter weight and focused solely on frontend interactivity
Cons of Alpine
- Limited to frontend functionality, unlike Motia's full-stack approach
- Less integrated with backend frameworks and databases
- May require additional libraries for complex state management
Code Comparison
Alpine:
<div x-data="{ open: false }">
<button @click="open = !open">Toggle</button>
<span x-show="open">Content</span>
</div>
Motia:
<div m-state="{ open: false }">
<button m-on:click="open = !open">Toggle</button>
<span m-if="open">Content</span>
</div>
Both frameworks use a similar declarative syntax for managing state and interactivity. Alpine uses x- prefixed attributes, while Motia uses m- prefixed attributes. The main difference lies in Motia's additional backend integration capabilities, which are not visible in this frontend-only example.
Alpine focuses on providing a lightweight solution for adding JavaScript-powered interactivity to static HTML, making it ideal for enhancing existing sites or building simple interactive components. Motia, on the other hand, aims to offer a more comprehensive full-stack development experience, potentially simplifying the development process for applications that require tight integration between frontend and backend.

What is iii?
iii is the easiest way to compose, extend, and observe every service in your stack in real time.
Every backend starts as a project before the first line of business logic. Queues, cron, HTTP, state, observability, agents, and sandboxes each usually bring their own integration story. iii collapses that into one live system surface.
iii worker add queue
iii worker add agent
iii worker add sandbox
iii worker add <anything>
Each worker joins the live catalog. Every other worker is notified and can call it immediately. Browse available workers at workers.iii.dev.
That is the agent story too: when a task needs a capability the system does not have, an agent can add a worker, discover its functions, call them, and trace what happened. Same interface a developer uses.
Three Primitives
Worker _ Function _ Trigger is the entire mental model.
Workers are processes that register with the iii engine and then register triggers and functions. A TypeScript API service is a worker. A Python data pipeline is a worker. A Rust microservice is a worker. Any functionality can be transformed into a worker with a few lines of code. Workers can also create other workers at runtime, so agents and applications can extend the system while it is running.
Triggers are anything that causes a function to run. A trigger can be a direct call to a function, an HTTP endpoint, a cron schedule, a queue subscription, a state change, a stream event, or anything else. Triggers are declarative: the Worker defines "this function runs when this thing happens," and iii handles routing, serialization, and delivery.
Functions are units of work with a stable identifier (e.g., content::classify,
orders::validate). It receives input, does work, and optionally returns output. Functions exist in
workers.
By mapping everything a service can do to these three primitives iii creates a development process that is both effortlessly composable, and completely observable.
What Changes
Before iii:
- New observability tool: uncountable integrations
- New agent harness: separate retry config, separate traces, separate timeouts
- New queue: vendor evaluation, procurement, and weeks of integration
After iii:
iii worker add observabilityiii worker add queue- Done. It is in the system, traceable, and callable.
Platform teams publish workers. Application teams register functions and declare triggers. Agents use the same catalog and the same function calls.
Extending iii is iii worker add. Composing iii is calling functions. Observing iii is opening the
trace.
Quick Start
Install iii:
curl -fsSL https://install.iii.dev/iii/main/install.sh | sh
Then scaffold and start a project:
iii project init myapp # scaffold a project
cd myapp
iii # start the engine
Full walkthrough at the Quickstart guide.
Add Workers
Install new capabilities into a project with iii worker add:
SDKs
| Language | Package | Install |
|---|---|---|
| Node.js | iii-sdk | pnpm add iii-sdk or npm install iii-sdk |
| Python | iii-sdk | pip install iii-sdk |
| Rust | iii-sdk | Add to Cargo.toml |
| Go | iii-sdk | go get github.com/iii-hq/iii/sdk/packages/go/iii |
Agent Skills
Install iii's agent-readable reference material for the engine primitives:
npx skills add iii-hq/iii/skills
These cover every iii primitive: HTTP endpoints, queues, cron, state, streams, custom triggers, and more. See skills/ for the full list.
Each worker in iii-hq/workers also ships its own skill. Install them alongside the worker itself:
npx skills add iii-hq/workers --list # list available worker skills
npx skills add iii-hq/workers --skill database # one worker
npx skills add iii-hq/workers --all # every worker skill
The engine's built-in workers (iii-queue, iii-state, iii-pubsub, iii-stream, iii-cron,
iii-http, iii-observability, iii-bridge, iii-exec, configuration) ship their skills in
this repo. Install one with npx skills add iii-hq/iii --full-depth --skill <name>; each worker's README under
engine/src/workers/ lists the exact iii worker add and skill command.
Console
The iii-console is a developer and operations console for inspecting workers, functions, triggers, queues, traces, logs, and real-time state. See the Console docs for setup and usage.
