# Technologies we use

> Technologies behind APPSOLN software and AI projects.

Proven, widely supported technologies APPSOLN uses to build, test, launch, and host software and AI.

## Technologies

- [React](https://appsoln.com/technologies/react/index.md): React is the most widely used technology for building the screens people click, type, and tap on in a web app. It powers everything from small booking tools to large company dashboards.
- [Next.js](https://appsoln.com/technologies/nextjs/index.md): Next.js is built on top of React and adds the things most businesses need: fast page loads, good search engine visibility, and a simple way to run the website and its back end together.
- [TypeScript](https://appsoln.com/technologies/typescript/index.md): TypeScript is a safer version of JavaScript, the language of the web. It checks the code as it is written, so many common mistakes are caught before the software goes live.
- [Node.js](https://appsoln.com/technologies/nodejs/index.md): 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.
- [Python](https://appsoln.com/technologies/python/index.md): Python is the most popular programming language today. It is used for web back ends, automating repetitive tasks, working with data, and almost all modern AI work.
- [.NET](https://appsoln.com/technologies/dotnet/index.md): .NET is Microsoft's platform for building business software, usually written in the C# language. Many companies run their core systems on it, and modern .NET works well in the cloud.
- [PostgreSQL](https://appsoln.com/technologies/postgresql/index.md): PostgreSQL is a popular, free, and very reliable database, the place where an app stores its information. It is trusted by startups and large companies alike.
- [Playwright](https://appsoln.com/technologies/playwright/index.md): Playwright is a modern tool that automatically opens your website in real browsers and clicks through it like a person would, checking that everything still works after each change.
- [Docker](https://appsoln.com/technologies/docker/index.md): Docker packages software together with everything it needs to run, into a container. That means it behaves the same on every computer and server, which removes a lot of it-works-on-my-machine problems.
- [Kubernetes](https://appsoln.com/technologies/kubernetes/index.md): Kubernetes runs many software containers across several servers, restarts anything that fails, and adds capacity when demand grows. It is the standard for running larger or busier systems.
- [Terraform](https://appsoln.com/technologies/terraform/index.md): Terraform lets you describe your cloud servers, databases, and networks in simple files instead of clicking through a web console. The same files can rebuild everything exactly, which makes changes safer and recovery faster.
- [AWS](https://appsoln.com/technologies/aws/index.md): Amazon Web Services (AWS) is the world's largest cloud provider. It lets you rent servers, databases, storage, and AI services by the hour instead of buying hardware.
- [Microsoft Azure](https://appsoln.com/technologies/azure/index.md): Microsoft Azure is Microsoft's cloud platform. It works closely with Microsoft 365, Windows, and .NET, and it offers servers, databases, and AI services, including Azure OpenAI.
- [Large Language Models (LLMs)](https://appsoln.com/technologies/llm-integration/index.md): Large language models, or LLMs, are the AI behind tools like ChatGPT, Claude, and Gemini. They can read and write text, which makes them useful for drafting replies, summarising documents, sorting requests, and pulling out details.
- [AI Document Search (RAG)](https://appsoln.com/technologies/ai-document-search/index.md): AI document search, often called RAG (retrieval-augmented generation), lets people ask a question in plain words and get an answer taken from your own documents, with a link to the source so they can check it.
