Tech Stack Selector

Answer four questions and get a recommended frontend, backend, mobile, database and cloud stack — with the reason for each choice shown. It recommends what actually fits — including technologies we do not sell, which are labelled as such. The rules behind it are printed further down the page, so you can see exactly why you got what you got and disagree with it.

Your project

Four questions. The recommendation updates as you change them.

Existing in-house skills usually matter more than small technical differences between stacks, because hiring and maintenance follow them.

Suggested stack

For your project

we build this better fit, but not a service we offer
Also worth considering

A starting point, not a final architecture. Integrations with systems you already run, in-house skills and compliance requirements often outweigh the general guidance above.

Starting points

Common project types and the stacks that suit them

The five shapes of project we are asked about most often, and what the selector returns for each.

Frontend, backend and database are shown; cloud is chosen separately and is usually Azure for .NET work and AWS otherwise.
Project Frontend Backend Database
Marketing website Web · no ecosystem preference · speed to launch WordPress WordPress MySQL
SaaS product / web app Web · JavaScript team · long-term scale React Node.js PostgreSQL, Redis
Enterprise internal system Web · Microsoft shop · long-term scale Angular ASP.NET Core Microsoft SQL Server
Mobile app, both platforms Mobile · no preference · speed to launch Flutter (mobile, no web frontend) Node.js PostgreSQL
Online store Web · no preference · speed to launch Shopify Shopify Shopify (hosted)
  • Marketing website: A content team needs to publish without a developer, and the platform already solves that.
  • SaaS product / web app: One language across frontend and backend, so the same engineers can work on both.
  • Enterprise internal system: Stays inside the Microsoft stack the business already runs, licenses and staffs.
  • Mobile app, both platforms: One codebase produces both iOS and Android builds.
  • Online store: Payments, checkout, tax and hosting are handled by the platform rather than built.

How these recommendations are made

There is no model or scoring engine behind this. It is a short list of rules, applied in order, and here they are in full:

  1. Your existing ecosystem wins first. If you tell it you are a .NET shop it will suggest ASP.NET Core and Microsoft SQL Server; a PHP team gets Laravel; a JavaScript team gets Node.js. Hiring and long-term maintenance follow the skills already in the business.
  2. The project type rules options in and out. A marketing site gets a CMS because a content team needs to publish without a developer. An online store optimising for launch speed gets a hosted platform, because payments, checkout and tax are solved problems.
  3. Where it runs decides the mobile answer. Needing iOS and Android from one codebase points to Flutter or React Native; a single platform leaves native Swift or Kotlin on the table.
  4. What you are optimising for breaks remaining ties. Speed favours platforms that solve problems out of the box, scale favours strongly typed and widely staffed stacks, lower build cost favours the largest talent pools.

Databases are limited to the three we publish work in — Microsoft SQL Server, MySQL and MongoDB. Cloud defaults to Azure for .NET projects and AWS otherwise, with Google Cloud suggested where the work is data or AI heavy. Nothing here considers cost or timeline, because neither is published on this site.

FAQ

Questions about this tool

How does this tech stack selector work?
It applies a fixed set of rules to four answers: what you are building, whether it needs to run on web or mobile, whether your team is already committed to an ecosystem such as .NET or PHP, and whether you are optimising for speed to launch, long-term scale or lower build cost. The rules are published on the page, so you can see why a particular stack was suggested.
Is the recommended stack the only option that would work?
No. Most projects can be built well in several stacks, and the differences often matter less than the team building it. Treat the result as a shortlist and a starting point for a conversation, not a verdict. Existing systems you must integrate with, in-house skills and compliance requirements frequently outweigh the general guidance here.
Does it only recommend things TechnoBrains sells?
No. It recommends what fits the project, and labels each result either "we build this" or "not a service we offer". Python is suggested for AI work and PostgreSQL as a general relational default, for example, because those are the right answers even though they are not published services. Anything we do build links through to the page describing that work.
When should I choose Flutter over native iOS and Android?
Flutter builds both platforms from a single codebase, so it suits products where the same features ship to iOS and Android and the interface is largely your own design. Separate native builds in Swift and Kotlin make more sense when you depend heavily on the newest platform-specific capabilities, need maximum performance for graphics or hardware access, or are only shipping to one platform.
Does this tool tell me what my project will cost?
No. It recommends a stack only. Cost depends on scope, integrations and the amount of design and testing involved, which needs a scoping conversation rather than a calculator.

Got a shortlist? Let's pressure-test it.

The stack matters less than the constraints around it — what you already run, who maintains it, and what has to integrate. Bring us the result and we will tell you where it holds up and where it does not.
