Our mission

We build software the right way.

Not vibe coding

We combine AI acceleration with genuine engineering discipline — specification, architecture, code review, and testing — to deliver production-ready software in two weeks.

What is FSGen

A full-stack application generator, not a freelancer marketplace

We are a software company that builds complete, production-ready applications with a fixed architecture, a fixed timeline, and a fixed price.
01

Full-Stack by Default

Every project includes frontend, API, database, authentication, cloud infrastructure, and deployment. Not just a prototype — a complete, working application.

The Generator Advantage

We have built our own AI agents, code scaffolding tools, and engineering workflow on top of a standardised architecture. This means 90% of every application already exists before development begins — our senior engineer focuses on your business logic.

FSGen is what you get when a software company automates its own delivery process and passes the efficiency directly to you.
Engineering philosophy

Three things we never compromise on

Predictability

Every project uses the same stack, the same process, and the same delivery timeline. No surprises. No scope creep. The AI feasibility analysis catches ambiguities before a single line of code is written.

Quality

AI generates the scaffolding. Senior engineers review every file. Automated tests validate every endpoint. You receive code that meets the same standard as in-house development — without the timeline or cost.

Ownership

You receive the complete source code, full IP transfer, and zero lock-in on delivery. No subscriptions, no proprietary platforms, no dependency on FSGen to keep your application running.

Why we built this

The broken status quo

You write a brief. The agency takes 2 weeks to respond with a proposal.

The proposal is €80k and 6 months. You negotiate. They reduce scope.

Development starts. Scope creep. The timeline slips. The budget grows.

6 months later: a prototype. 3 more months: a v1. Maybe.

You own nothing. The agency owns the architecture. You pay maintenance forever.

AI arrived. The agencies updated their pitch decks. Nothing else changed.

We built FSGen to fix this.

We standardised the architecture, automated the repetitive parts, and structured the process so every project follows the same path from brief to delivery. The result is a 2-week delivery at a fraction of the traditional cost — without cutting corners on engineering quality.

Our process

7 steps, every time

01

Upload a brief — PDF, document, or description

02

AI feasibility analysis identifies gaps and confirms scope

03

You confirm architecture, fill gaps, and sign the contract

04
AI scaffolding generates 90% of the application structure
05

Senior engineer implements business logic and reviews every file

06

Automated test suite validates all endpoints and flows

07

Delivery: source code, infrastructure, and handover documentation

The same 7 steps. Every project. No shortcuts.

Engineering standards

What "production-ready" means to us

Typed, documented APIs

Every endpoint is typed, validated, and built RESTful API-first. No guessing what the API expects.

Security by design

JWT auth, RBAC, input validation, secrets management, HTTPS, and GDPR-compliant data handling — built in from day one.

Scalable architecture

Cloud-native deployment on AWS. Auto-scaling compute, managed databases, CDN delivery. Built to grow.

Clean, maintainable code

Clean Architecture, SOLID principles, and consistent patterns throughout. Any developer can pick up the codebase and extend it.

No lock-in

Standard open-source stack. No proprietary platforms. No subscriptions. Run it anywhere.

Full test coverage

Unit tests, integration tests, and end-to-end validation. Minimum 80% coverage on delivery.

Who we work with

Built for two types of client

Entrepreneurs & Startups

You have a product idea, a brief, and a deadline. You don't have time to hire a team, manage a project, or wait 6 months for delivery.


Fixed price — no budget surprises

2-week delivery — launch before competitors

Full source code — your asset, not ours

Engineering Teams

You need an internal tool, a client portal, or a new module delivered quickly — without pulling your core team off their roadmap.


Consistent architecture aligned with your stack

Clean code your team can extend immediately

No project management overhead

Delivery in 2 weeks, not 2 quarters

What we don't do

We are deliberately narrow

Custom mobile applications (iOS / Android)

Real-time video or audio streaming platforms

Legacy system migrations without clear data models

Projects without a written specification

Ongoing maintenance retainers or SLA contracts

Anything outside our fixed architecture

Our scope is narrow by design.
That's what makes 2-week delivery possible.
What drives us

Our values

Honesty first

We tell you if your project won't work before you pay. We turn away projects we can't deliver. We don't oversell.

The client owns the code

Full IP transfer on delivery. No subscriptions, no lock-in, no strings attached.

Engineers, not salespeople

The people who scope your project are the people who build it. No account managers between you and the engineering team.

Process over heroics

We don't rely on brilliant individuals working nights. We rely on a disciplined process that produces consistent results every time.

Automation at every layer

We automate what can be automated — from feasibility analysis to code generation to testing. Humans focus on judgement calls.

One standard, every client

The same architecture, the same process, the same quality bar — whether you're a first-time founder or an enterprise IT team.
