Conversation and brief
You tell us what you want to achieve and we ask questions. Scope, schedule and quote reach you within 48 hours of the call.
We design and code them from scratch, no templates.

Before we draw anything, we agree what the site is for, who should land on it and how you will know it works.
Strategy and direction
Every screen is laid out to lead the customer to one thing: an inquiry, a purchase or a call to you.
Design that sells
We turn the design into code on Astro or Next.js. You sign off once the site scores at least 85 in PageSpeed Mobile.
Build and code
Smooth scrolling, GSAP animation and 3D models where they have something to show. Weaker devices get a simpler version.
Animation and 3D
A business-card site from PLN 3,000 net, a site with a content panel from PLN 4,500. Ready in 2–6 weeks, with technical SEO and WCAG 2.2 AA accessibility.

A store on Shopify or headless, with BLIK, Przelewy24, InPost and DPD. From PLN 8,000 net, live in 3–12 weeks.

A website for a hotel, restaurant, law firm, accounting firm, construction or transport company. From PLN 4,500 net, 2–6 weeks.

A client dashboard, SaaS or MVP on Next.js and React, with sign-in, database and integrations. From PLN 15,000 net, 4–16 weeks.

PWA or Capacitor: one codebase for iOS and Android, push and offline mode. From PLN 12,000 net, 3–12 weeks.
Astro for websites, Next.js for apps and stores, with rendering (SSR, SSG or ISR) chosen by how often the content changes.
Animation and 3D, as on this site, loaded so they do not hurt the PageSpeed score.
You change texts, images, pages and products yourself, in a panel on your account.
Visibility in Google, apps that also work offline, and connections between the site and your CRM, payments and couriers.
You tell us what you want to achieve and we ask questions. Scope, schedule and quote reach you within 48 hours of the call.
We design in Figma, screen by screen, with your feedback along the way. The source files stay with you.
We code to the design, test on real devices and check accessibility. The site goes live on your domain.
For the first 30 days after handover we fix bugs in our code for free. After that we support the site in a scope we agree together.
Behind eriz.studio is me, Kacper Baranowski. I run every project personally, from the first call to launch and support. You write to the person who designs it, codes it and answers for it.
More about the studio
Describe it in a few sentences. We reply with specifics, a few questions to narrow things down, and a time for a call.
Start with a free quoteYes. Every service has its own scope and price, so you can order the Figma design alone, the build of a finished design, or SEO on a site that is already live. If you are starting from scratch, pick an offer (a website, a store or an app): it already has the right set of services, one schedule and one person to talk to, so nothing gets lost between stages.
It depends on what it is built on. We start with a review: speed, accessibility, visibility in Google and how easily you can edit the content. If the foundation is sound, we add SEO and analytics or integrations, or take the site under our care. If every change needs a developer and the page takes seconds to load, a new site usually costs less than patching the old one. After the review you get an answer to both questions: what is worth keeping and what a new site would cost.
With a message through the form or to [email protected]: tell us what you need and by when. We reply by the end of the next business day and set up a call, where we ask about the goal, the audience and your current site. Within 48 hours of the call you get a free quote with the scope and schedule spelled out. Only then do you decide whether we go ahead.
A business-card site starts from PLN 3,000 net, a business website with a content panel and an industry website from PLN 4,500, a store from PLN 8,000, a mobile app from PLN 12,000 and a web app from PLN 15,000. Fixes to a site you already have start from PLN 1,500, and care from PLN 250 a month. Every price is in our pricing. The final figure depends on the number of pages, the integrations and whether you already have content, photos and branding. Every item in the quote is priced separately, so you can see what you are paying for and what can wait.
A business or industry website takes 2–6 weeks from an approved brief, a store 3–12 weeks, a web app 4–16 and a mobile app 3–12. Most of the waiting usually comes from content and photos on your side, so the sooner we have them, the closer we land to the lower end. If the site has to be ready for a specific date, say before the season or a trade fair, tell us on the call and we plan the schedule backwards from it.
Yes. The site comes with a content panel, like Sanity here: you change texts, images, pages and products without a developer. At handover you get a walkthrough of the panel and the documentation.
Bugs in our code are fixed free for 30 days from handover. After that you stay with us on ongoing care or move on with someone else: the domain, hosting, panel, code and Figma files are yours from the start.
Got a project?
Two sentences: what you have and what you need. We will ask the rest on a call.
Your message went straight to Kacper. He replies by the next business day at the latest.
