What Is a Tech Stack?
Quick answer
A tech stack is the set of technologies that together run a piece of software: the front end users see, the back end that holds the business logic, the database, the hosting and infrastructure, and the outside services it calls. In business and marketing, the phrase also means the set of software tools a company runs on, such as its CRM, email and analytics. Below: the layers with examples, well-known named stacks, what developers actually use according to Stack Overflow's 2025 and 2026 surveys, and how to choose one.
Key takeaways
- A software tech stack has five layers: front end (what users see), back end (business logic and APIs), database, hosting and infrastructure, and third-party services such as payments, email and maps.
- Named stacks are shorthand for common combinations: LAMP (Linux, Apache, MySQL, PHP), MEAN (MongoDB, Express, Angular, Node.js) and MERN (MongoDB, Express, React, Node.js).
- Stack Overflow's 2026 survey lists JavaScript (62.0%), SQL (58.4%), HTML/CSS (58.2%) and Python (58.0%) as the most used languages, and PostgreSQL (57.9%) as the most used database.
- In business and marketing, a tech stack means the set of software tools a company runs on: CRM, email, analytics, payments and the integrations between them.
- Choose a stack by what the product needs, who will maintain it, and how easy it is to hire for, not by novelty. Clutch lists every major stack it tracks at the same $25 to $49 average hourly band.
A tech stack is the set of technologies that together run a piece of software: the front end people see, the back end that holds the business logic, the database, the hosting and infrastructure, and the outside services it calls for things like payments and email. In business and marketing, the phrase also means the set of software tools a company runs on, such as its CRM, email platform and analytics.
Checked October 31, 2026. We used the Stack Overflow Developer Survey (2026 for languages and databases, 2025 for frameworks and cloud platforms) and Clutch’s pricing guides (updated Sep 21, 2026).
What are the layers of a tech stack?
| Layer | What it does | Common examples |
|---|---|---|
| Front end | The screens users see and click in a browser or app | HTML, CSS, JavaScript or TypeScript, React, Angular, Vue; Swift and Kotlin for native mobile |
| Back end | Business rules, user accounts, APIs | Node.js, Python (Django, FastAPI), Java, C# (.NET), PHP, Ruby on Rails, Go |
| Database | Stores the data | PostgreSQL, MySQL, SQLite, Microsoft SQL Server, MongoDB, Redis |
| Hosting and infrastructure | Runs the code and scales it | AWS, Microsoft Azure, Google Cloud, Cloudflare, containers such as Docker |
| Third-party services | Features you rent instead of build | Payments, email, SMS, maps, authentication, AI models, analytics |
Around those sit the tools used to build and run the software: source control, automated tests, deployment pipelines and monitoring.
What are well-known named stacks?
| Name | Components | Notes |
|---|---|---|
| LAMP | Linux, Apache, MySQL, PHP | The classic web server stack; WordPress runs on PHP and MySQL |
| MEAN | MongoDB, Express, Angular, Node.js | JavaScript end to end |
| MERN | MongoDB, Express, React, Node.js | Same as MEAN with React on the front end |
| .NET | C#, ASP.NET, SQL Server, often Azure | Common in enterprises that run Microsoft systems |
| Django | Python, Django, usually PostgreSQL | Popular where data work and web apps meet |
| JAMstack | JavaScript, APIs, pre-built markup | Fast content sites served from a CDN |
Most real products do not match a named stack exactly. They pick a front end, a back end and a database that fit, then add services.
What do developers actually use?
Sources: Stack Overflow Developer Survey 2026, Technology and 2025, Technology, all respondents, checked Oct 31, 2026. The 2026 technology page does not include a web framework ranking, so framework and cloud figures are from 2025.
The fuller picture:
| Category | Most used, share of respondents |
|---|---|
| Languages (2026) | JavaScript 62.0%, SQL 58.4%, HTML/CSS 58.2%, Python 58.0%, Bash/Shell 51.3%, TypeScript 43.8%, Java 27.6%, C# 27.1% |
| Databases (2026) | PostgreSQL 57.9%, SQLite 42.1%, MySQL 35.1%, Redis 28.3%, Microsoft SQL Server 27.1% |
| Web frameworks and technologies (2025) | Node.js 48.7%, React 44.7%, jQuery 23.4%, Next.js 20.8%, Express 19.9% |
| Cloud platforms (2025) | AWS 43.3%, Microsoft Azure 26.3%, Google Cloud 24.6%, Cloudflare 20.1%, Firebase 13.1% |
Popularity matters for one practical reason: the more people use a technology, the easier it is to hire someone to maintain your software in five years.
What does tech stack mean in business and marketing?
Outside engineering, “tech stack” usually means the software tools a company runs on: a CRM, email marketing, analytics, scheduling, payments, a help desk and the integrations that pass data between them. A marketing tech stack is the part used to attract, convert and report on customers. The common problem is not any single tool but the gaps between them, where leads and data get retyped or lost. Connecting a CRM to the rest of the stack is what CRM integration services cover.
How do you choose a tech stack?
Start from the product, then check the people:
- What the product needs. Real-time features, heavy data processing, offline mobile use and strict compliance each point to particular choices.
- Mobile or not. Native iOS and Android, a cross-platform framework, or a progressive web app.
- Integrations. Some systems have official libraries for certain languages; using them saves time.
- Who maintains it. Your current team’s skills, or how easy it is to hire for the stack where you are.
- Lifespan. Widely used, actively maintained technologies age better than niche ones.
- Hosting and running cost. Match the infrastructure to expected traffic, not to a hypothetical peak.
The stack itself rarely changes the hourly price much. Clutch lists every technology it tracks, from .NET, Java, Flutter, Laravel and Go to WordPress, PHP, Ruby on Rails, Drupal, Django and ReactJS, at the same $25 to $49 average hourly band (software and web guides, updated Sep 21, 2026, checked Oct 31, 2026). Where stack choice costs money is later: an outdated or unusual stack is harder to staff, which is a common reason for legacy software modernization.
How do we choose a stack?
Per project, from the product’s needs and who will maintain it, and we write down why so the next team can follow the reasoning. We do not push one stack for every client.
