Ready-made components vs. custom UI – how to approach design?

How we launched Bitelink.pl in 2 weeks, saving over 30% of the budget using ready-made components

As a UI/UX Designer, I often face a dilemma: should I design the interface from scratch or use prebuilt UI libraries? Custom UI offers full control and uniqueness, but the reality for solopreneurs and bootstrapped founders is a constant pressure of time, budget, and fast market validation.

A great example is our project Bitelink.pl – a platform for generating and managing QR codes that had to go from idea to MVP in just 2 weeks.

It was just two of us: a designer and a developer.

Goal: quickly test the idea, get an initial Product-Market Fit signal, and gather feedback from early users.

Why did we choose ready-made components?

Using a UI library allowed us to:

  • Save over 30% of the budget – instead of spending thousands of euros designing and coding basic elements, we invested in market testing.
  • Deliver the MVP 3x faster – instead of 6 weeks, we needed only 2, giving us a head start over the competition.
  • Maintain a consistent UX/UI – we avoided design chaos by using proven interaction patterns.

Design tip

If you want to speed up development, choose a reliable UI library that works well with your framework (e.g., Material UI for React).

When do ready-made components really make sense?

UI libraries (Material UI, Ant Design, Alignui, Tailwind UI) work best when:

  • You have limited time and resources.
  • You need to quickly validate an idea (MVP).
  • You want to ensure smooth designer-developer collaboration.

When is custom UI a must?

Custom UI is essential if:

  • Your brand demands uniqueness and strong visual identity.
  • You need custom animations or interactions.
  • You care about maximum performance and full control over code.

How to create an effective “hybrid” UI system?

In Bitelink.pl, we applied a hybrid approach:

  • Basic elements (forms, buttons, navigation) – from a ready-made library (Material UI).
  • Key screens (QR code editor, user dashboard) – custom-designed to give the product a distinctive edge.

This gave users a consistent yet recognizable interface.

Design tip

Always adapt the branding (colors, icons, typography) of ready-made components to your UI to avoid a generic app look.

What did the Bitelink.pl MVP implementation look like?

1. From idea to MVP (2 weeks)

  • 3 days: layout and flow design using prebuilt components.
  • Parallel implementation by the developer using Material UI.
  • Key screens (QR code generator) – built custom.
  • Iterative testing and UX/UI tweaks over the following days.

Results:

  • We delivered a working MVP in just 2 weeks.
  • We confirmed initial Product-Market Fit without unnecessary costs.
  • We saved over 30% of the budget compared to a fully custom solution.

2. Challenges we faced

  • Some library components required non-trivial modifications.
  • It was necessary to adjust branding (colors, icons) to maintain a unique identity.

Our custom FAST method for deciding between ready-made and custom components

In Bitelink.pl, we created a custom decision-making method called FAST:

  • Fit – Does the library meet our UX/UI needs?
  • Adaptability – Can we easily customize styles and interactions?
  • Speed – Does the library significantly accelerate development?
  • Testability – Does it allow for fast hypothesis validation?

Thanks to FAST, we could quickly assess when to use ready-made components and when to build something custom.

Design tip

Test UI libraries early in the project. If, after a few days, it turns out that adapting them is more time-consuming than building from scratch, it’s better to switch to a custom solution.

Conclusion

Choosing ready-made components is a matter of strategy. Using libraries doesn’t mean giving up uniqueness—it’s a strategic choice that saves resources in the early stage. After validating the market, you can always invest in a more custom design.
