In modern software development, the goal is always to deliver value faster. Yet, even the simplest piece of business logic—like adding two numbers or processing a user signup—often requires a mountain of boilerplate code, server configuration, and deployment pipelines to become a production-ready API. This friction slows down innovation and distracts developers from what they do best: writing code.
What if you could bypass that complexity entirely? What if you could write a function, define its inputs and outputs, and have it instantly become a scalable, secure, and reliable API?
This is the core promise of Functions.do, a platform designed to restore focus and dramatically boost developer productivity by making function execution simple and, most importantly, typesafe.
Serverless platforms like AWS Lambda and Google Cloud Functions were a major leap forward, freeing us from managing physical servers. However, they introduced their own set of complexities. Developers still need to grapple with:
These platforms are powerful, but they still require you to think like a DevOps engineer. Functions.do offers a higher-level, fully integrated experience that abstracts away this overhead.
Functions.do is built on a simple premise: Reliable Function Execution, Simplified. The entire platform is architected around the concept of typesafe contracts. Instead of just writing a function, you declare its schema—the exact shape of the data it expects to receive and the data it guarantees to return.
Our platform uses these schemas to enforce data integrity automatically.
This "typesafe by design" approach eliminates an entire class of runtime errors, makes APIs self-documenting, and builds a foundation of trust and reliability between services.
Let's see how simple it is to turn logic into a robust API. Here’s how you define a a typesafe adder function on our platform:
That’s it. In this small block of code, you have:
There's no need to configure an API gateway, write validation code, or manage server infrastructure. You focus on your code; we handle the rest.
The simplicity and reliability of Functions.do make it the ideal backbone for an exciting new frontier: agentic workflows. As AI agents and automated systems become more sophisticated, they need a toolbox of reliable, predictable tools to perform tasks.
A function on our platform isn't just a piece of code; it's a verifiable capability. Because the inputs and outputs are guaranteed, an AI agent can confidently use your adder function, a sendEmail function, or a processOrder function, knowing it will work as advertised every single time. This turns your business logic into a reliable, composable toolkit for building powerful automations and intelligent systems.
Functions.do is more than just another Function-as-a-Service (FaaS) platform. It's a productivity multiplier designed for the modern developer.
Stop wrestling with infrastructure and start building what matters. Experience a new level of productivity and reliability in your application development.

import { Function } from 'functions.do';
// Define a typesafe function with input and output schemas
const adder = new Function({
name: 'adder',
input: { a: 'number', b: 'number' },
output: { sum: 'number' },
handler: async ({ a, b }) => {
// Core logic is simple and focused
return { sum: a + b };
},
});
// Execute the function via the SDK
const result = await adder.run({ a: 5, b: 7 });
// result is guaranteed to be { sum: 12 }
console.log(result.sum);
