Prague Core
Prague Core — software industry, Czech Republic

Software studio · Prague

We build websites, web apps and games.

You are not buying a template or a rental. You get the source code, the credentials and the data — and a site you can extend in three years rather than throw away. Design, code and hosting in one place.

  • 7 projects you can open right now
  • 1 working day — our usual reply time
  • 0 CZK for the first conversation and the quote

What we do

Three kinds of work, one signature. The same holds for all of them: no template, no third-party tracking scripts, and a deployment you can keep running after we hand it over.

Websites

A site whose job is to bring in enquiries. Fast, readable on a phone and written so that search engines can find it.

  • Designed for the brand, not bought as a template
  • Copy and structure built for search
  • Multiple languages and accessibility
  • Domain, mail and fast loading anywhere in the world

Web applications

For when a website is not enough and you need accounts, data and rules. Your own database and API on your own server — no rented platform you cannot leave.

  • Sign-in, roles and content moderation
  • Database, API and an admin interface
  • Payments and third-party integrations
  • Hosting, backups and monitoring after launch

Games and interactive campaigns

A game or a quiz on your site that people finish and pass on. It runs the moment someone clicks a link — no install and no app store.

  • Game mechanics, tuning and playtesting
  • Artwork and sound made in house
  • Mouse, touch and keyboard controls
  • Campaigns, leaderboards and sharing

Work

What is live and what you can open right now. All of it was made here, from the design to the deployment.

The design collection — a grid of interface samples

Designs

Live

Sample collection

More than a hundred standalone pages, each one an idea for a look — from a cake shop to a holographic command deck. Hover a tile and the preview runs live; click to open it in full. The pages are in Czech.

Live

Website

The page you are reading. The logo, the textures, the typesetting, the words and the deployment were all made here. It has no JavaScript, no third-party domain and no cookie banner — and it still switches theme, language and colour set.

The Gem Stall marketplace — listings with filters and categories

Gem Stall

Live

Web app

A community marketplace. Free listings, no commission, photos, accounts, moderation. Its own database and API on our own server.

The Real or Not game — its opening screen with the rules

Real or Not

Live

Game

Ten rounds, two images in each. One was taken by a person, the other generated by a machine. Rounds go from the oldest models to the newest, so your own score shows you how fast this has moved.

Play it
The Heat game mid-play — the arena with the score, shards and the arc around the core

Heat

Live

Game

A browser arcade. You guard the core of a circular arena with a single arc — but every deflection speeds the shard up for good. The difficulty is exactly what you did to yourself.

Play it
The Neon Bloom game — its opening menu

Neon Bloom

Live

Game

A puzzle of lights. Send a spark into a cluster and the glow runs down a chain — but shadows swallow it, ghosts can only be caught while lit, and the vortex reshuffles everything. Twelve rounds per series.

Play it
The Moth game — the flock trails the lantern as one moth reaches the gate

Moth

Live

Game

A game about light. You steer no moths — only the lantern they trust, and the brighter it burns the sooner a flame comes for it. Shadows blind the flock but douse the fire. Twelve nights till dawn.

Play it
The Harvester game — a field full of gems, a golden find on its countdown, collector drones and the upgrade list

Harvester

Live

Game

Ores, ice and gems drift through space. You collect them by hand and choose what to reach for first. Then you spend the essence on drones that do it better — and the rig keeps working while you are away.

How it works

Four steps and no surprises in between. You know the price and the date before the first line of code is written.

  1. The conversation

    Half an hour about what the thing has to do and who it is for. Free and without commitment.

  2. The quote

    Scope, a fixed price and a date, in writing. What is not in the quote is not billed; anything added along the way is agreed first.

  3. The build

    A working version runs at an address you can open from the first week. You comment as it goes, not once it is finished.

  4. The launch

    Deployment, domain, mail, plus speed and accessibility measured. We hand over the accounts and the source code — and stay reachable.

Pricing

The figures below are starting points; what pushes them up is scope, the number of languages and third-party integrations. Your number comes in the quote after the first conversation and does not change from then on — what is not in the quote is not billed.

All prices are excluding VAT. We are VAT registered, so 21% is added.

Or just write to info@praguecore.com — a few sentences about what you need is enough.

Questions we get

How long does it take?

Two to three weeks for a website, six to ten for an application. The date is in the quote and it holds; if the scope changes along the way, the date is renegotiated with it.

How do we pay?

By bank transfer, against an invoice. We go through the terms in the first conversation — we try to fit around what suits you, and it usually is not a problem.

Who owns the code and the data?

You do. On handover you get the source code and the credentials to the domain, the database and the hosting. Nothing is locked inside a platform you cannot leave.

Where does it run?

Static sites on the Cloudflare edge network, so they load just as fast from anywhere. Applications with data on our own server, next to the database. Both can be moved to you.

Do you look after it once it is live?

Yes. Hosting, backups and monitoring are a flat fee from 500 CZK a month. Further work is agreed separately and quoted up front, the same way the project is. The flat fee is not compulsory — if you would rather run it yourself, we hand it over.

Do you do the artwork and the copy too?

Yes, and it is included. This page is the proof: the logo, the textures, the typesetting and every sentence were made here. If you have your own materials, we work with them.

Will the site need a cookie banner?

For a website, no. With no third-party script and no tracking there is nothing to ask consent for — so the banner that drives visitors away is gone, and so is the worry around it. This page is the proof: no JavaScript at all, and it still switches theme and language. For an application with accounts it depends on what it collects, and we say so up front.

Get in touch
