Does this sound familiar?

Typical challenges we solve with custom applications

Excel sheets everywhere

Critical business processes based on Excel files sent by email. Version chaos, formula errors, no access control.

Expensive off-the-shelf tools don't fit

You pay for features you don't use. Ready-made systems require you to adjust your processes instead of adapting to you.

Traditional IT takes forever

Quotes for 6-12 months and hundreds of thousands. By the time the application is ready, your needs will have changed.

Systems don't talk to each other

Data in CRM, orders in ERP, invoices in the accounting system. Manual retyping and risk of errors.

Unique processes

Your business has specific requirements that off-the-shelf solutions don't support. You need something tailor-made.

Your team needs tools

Employees waste time on manual tasks an application could handle. Lack of tools lowers productivity.

Why custom applications?

Benefits of building web applications tailored to your needs

3-5 wks
MVP ready

Fast delivery

MVP ready in 3-5 weeks, full application in 2-3 months. We work iteratively - you see progress every few days, not after months of waiting.

100%
fit

Tailored to your needs

We build exactly what you need - without unnecessary features that only complicate things. Every functionality has its business justification.

Your code
full ownership

Full control and ownership

Your application, your data, your source code. No vendor lock-in - you can develop the application with us, on your own or with any other team.

// Your code, your rules
const yourApp = {;
owner: "you",
control: "full",
vendorLock: false
}

Frequently asked questions

We answer common concerns about custom applications

MVP (minimum viable product) - from PLN 25-40k. A moderately advanced web application (user panel, integrations, business logic) - PLN 50-80k. A complex enterprise system - from PLN 100k. The cost depends on the scope of functionality, but you receive the source code and pay no monthly license fees.
MVP ready for testing - 3-5 weeks. Full web application - 2-3 months. Complex enterprise system - 4-6 months. We work iteratively - every 2 weeks we deliver a working version you can test, and we build subsequent features based on it.
Yes! The source code belongs 100% to you. You get full access to a GitHub/GitLab repository with all the code, technical documentation and deployment instructions. You can develop the application on your own, with us or with any other team. No vendor lock-in - you are independent.
The choice is yours! We can deploy the application on AWS, Google Cloud, Azure, DigitalOcean or your own server. We will help you choose the optimal solution in terms of cost, performance and scalability. You can also change hosting at any time - the code belongs to you.
Yes! We design applications with scalability in mind. We use proven technologies (React, Node.js, Python) and architectures (microservices, serverless) that handle millions of users. The application can grow without limits - we add new servers, optimize the database, introduce caching. Full control over performance.
We develop the application iteratively! We add new features in 1-2 week sprints. You can commission us to do the development or - if you have your own team - we hand over the code and documentation. Thanks to clean code and good practices, changes are predictable and safe. The application evolves together with your business.
Yes! We build all web applications as fully responsive - they work perfectly on computers, tablets and phones. Users can access the application in a browser on any device. Progressive Web App (PWA) also lets you add an icon to the phone home screen for quick access.
Hosting (AWS/Google Cloud/Azure): PLN 100-500/month (depends on traffic). Database: included in hosting. Monitoring and backup: PLN 50-200/month. Technical support: optional packages from PLN 1000/month. Development and new features: billed per project or as a subscription. No license fees - the code belongs to you.
