# Node.js development for APIs and back ends that connect your tools

> APPSOLN builds Node.js back ends and APIs that power web apps, connect your business tools, and handle real-time features such as chat and live updates.

Node.js runs the behind-the-scenes part of many web apps: the part that saves data, talks to other systems, and sends information to the screens people see. It uses the same language as the website itself.

## For small businesses

A small business might use Node.js to connect a website to a CRM, send automatic emails, or power a booking system.

## For larger companies

A large company might use Node.js for APIs that many apps share, integrations between systems, or real-time features such as live dashboards.

## Common questions

### Should our back end be Node.js, Python, or .NET?

It depends on what you have and what you need. Node.js is great for web apps and integrations, Python for data and AI, and .NET when your company already runs on Microsoft technology. We will recommend honestly.
