Prague Core — software industry, Czech Republic

Software studio · Prague

We build websites, web apps and games.

You don’t buy a template or rent a platform. You get the source code, the logins and the data — and a site you can extend in three years, not throw away. Design, code and hosting, all in one place.

Website concepts, apps and games

What we do

Three kinds of work, one approach. 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 isn’t enough and you need accounts, data and rules. Your own database and API on your own server — no rented platform you can’t 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 we have built and what you can open right now. All of it was made here, from the design to the deployment.

Web applications

Live and entirely ours — from the database to the domain.

Preview of the Gem Stall marketplace — a list of listings with filters and categories

Live

Gem Stall

A neighbourhood marketplace for second-hand things. Listings are free with no commission, deals are arranged in the listing thread and paid in person on pickup.

  • A listing starts with a photo — details can be filled in from it, and several items can be shot in a row
  • Listing threads that only the buyer and the seller can read
  • Search by city within 10, 25 or 50 km, by condition and by price
  • Sign-in, moderation, terms of use and a privacy policy
  • Its own database (PostgreSQL) and API on our own server — nothing rented

  • Category filters and search by role, company or location
  • Shift applications, worker selection and waiting lists
  • Personal shift overview and favourite companies

Games and a book

The games are our own; a campaign game for you is built the same way, in your brand and on your domain. Plus one book getting ready for release.

The Real or Not game mid-play — two pictures to compare and the bars of rounds hit and missed

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 — night eleven: the flock trails the lantern, a flame lurks nearby and the golden gate glows on the right

Moth

Live

Game

A game about light. You don’t steer the 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 — the Ice Ring: ice crystals and a golden find in the field, 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’re away.

Play it
The Slunovrat game — a circular colonnaded shrine on a clifftop, columns of light rising above the beacons

Slunovrat

Live

Game

The sun sinks toward the sea, and the light left to draw on sinks with it. You carry it from the sunlit patches to the beacons of a ruined shrine — six rounds, eighteen fires, dusk closer each time.

Play it
The FOLDWAR game — two stone keeps on a paper stage, a red and a blue army meeting in the single lane between them, the unit shop below

FOLDWAR

Live

Game

Two keeps, one lane, five ages. You buy units with gold, hold the line and bank experience — then turn the page into the next age, where everything costs more and hits harder.

Play it
The Tower game — a lane winding through the quarry, towers standing along it with their range rings drawn, a wave walking the line and damage numbers over the hits

Tower

Live

Game

One lane runs through the quarry and everything that wants past your gate walks it. You build towers and take each down one of three paths; between waves you pick one modifier of three. Thirty-six missions.

Play it
The Hive game — a bee garden on a sunny afternoon, three painted hives among flowering meadows, a fence around them and forest beyond, with the build bar below

Hive

Live

Game

A patch of field, one hive and a whole summer. Bees fly to the nearest meadow in bloom, so what matters is where you put things. Honey buys the next meadow — but storms tear the lids off and wasps go for the fullest hive.

Play it
The AI That Works book page — a pale cover on a dark page, with the title and the figures beside it

AI That Works

In progress

Book

A field guide to picking and using AI tools — images, code, video, voice, music, writing, research and agents. 136 pages across 15 chapters, with 60+ tools checked against the vendors’ own pricing.

Read about it

The code, the credentials and the data are yours.

After handover nothing stays locked with us or inside someone else’s platform.

Want something like this? Tell us what you need A link to a site you like and a few lines about what you need is enough.

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 on what it needs to do and who it’s for. Free and without commitment.

  2. The quote

    Scope, a fixed price and a date, in writing. If it’s not in the quote, you don’t pay for it. Anything added along the way is agreed first.

  3. The build

    From the first week there’s a working version at a link you can open. You give feedback as it takes shape, not once it’s done.

  4. The launch

    Deployment, domain, mail, with speed and accessibility tested. We hand over the accounts and the source code — and we stay available afterwards.

Pricing

Your final price comes in the quote after the first conversation and doesn’t change from then on — if it’s not in the quote, you don’t pay for it. The figures below are starting points; scope, the number of languages and third-party integrations push them up.

After launch

  • CZK 500 / month hosting a small site
  • CZK 1,200 / month a site with data, or a game — includes an hour of changes
  • CZK 2,500 / month an application with accounts — includes an hour of changes

Hosting covers the server, the domain, mail, backups and uptime monitoring; the upper two tiers add an hour of small changes a month. The first conversation and the quote are free.

All prices exclude VAT. Czech clients and private individuals pay 21% VAT on top (for consumers that comes to CZK 47,190 / 181,500 / 96,800, and running costs from CZK 605 / 1,452 / 3,025 a month, VAT included); VAT-registered businesses elsewhere in the EU are invoiced under the reverse charge, and clients outside the EU without Czech VAT. Prices are in Czech koruna — the budget you mention can be in any currency.

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

Questions & answers

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 does payment work?

By bank transfer, against an invoice. We go through the terms in the first conversation — we try to fit around what suits you.

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 can’t 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.

What do you build it with?

Websites as fast static pages without needless dependencies, applications on a PostgreSQL database with their own API, browser games that run from a link, with no install. The code is readable and handed over in full.

Do you take on projects from outside the Czech Republic?

Yes. We work in English, by email and video call, so there’s no need to meet in person. We’re on Central European Time — the same as Berlin and Warsaw, an hour ahead of London and Lisbon.

Do you look after it once it’s live?

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

Do you do the artwork and the copy too?

Yes, and it’s 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?

This site sets no cookies and uses no analytics or tracking scripts, so it has no cookie banner. JavaScript loads from our own domain for visual effects and animation. For your website, it depends on the services used and the data stored; we discuss that up front.

Get in touch

Write a few sentences about what you need and by when. Within one working day we’ll tell you whether we can do it, what it will cost and when it can be ready. The first conversation and the quote are free and commit you to nothing.
