What is Microfn?

Section titled “What is Microfn?”

Microfn is a serverless function platform that allows you to write JavaScript and TypeScript functions directly in your browser and deploy them instantly to AWS Lambda. With built-in modules for AI, storage, secrets management, and more, you can build powerful serverless applications without managing infrastructure.

Key Features

Section titled “Key Features”

Browser-Based Development

Write and test your functions directly in the browser with a full-featured code editor supporting TypeScript and auto-completion.

Instant Deployment

Deploy your functions to AWS Lambda with a single click. No build steps, no configuration files, just write and deploy.

Built-in Modules

Access powerful modules for AI (@microfn/ai), key-value storage (@microfn/kv), secrets management (@microfn/secret), and more.

Multiple Triggers

Trigger your functions via HTTP webhooks, scheduled cron jobs, email, or integrate with AI assistants through MCP.

Quick Example

Section titled “Quick Example”
import kv from "@microfn/kv";
import { askAi } from "@microfn/ai";


export default async function main(input: any) {
  // Store data that persists across executions
  await kv.set("lastRequest", new Date().toISOString());


  // Use AI to process input
  const analysis = await askAi(`Analyze this data: ${JSON.stringify(input)}`);


  return {
    timestamp: await kv.get("lastRequest"),
    analysis
  };
}
