About the studio

Ostohlo web studio — what we do

Ostohlo is a full-cycle web studio. We design, build and ship websites, online stores and web apps that solve concrete business goals: attracting customers, selling and automating processes. We take a project at any stage — from an idea and prototype to launch, analytics and ongoing growth.

We follow a transparent process: research and strategy, UX/UI design, development on a modern stack, testing and launch. We show interim results at every step, and fix timelines and cost in the contract. The code and all accounts stay yours — with no lock-in to the studio.

Our portfolio is made of real, live products: fintech, marketplaces, SaaS tools and media. We care equally about design and engineering: a website should be not only beautiful but fast, accessible and clear to search engines and AI. We build every site multilingual — Russian, English, Ukrainian — with correct SEO markup.

Frequently asked questions

Didn’t find your answer?

Ask us directly
How much does website development cost?

The cost depends on the project type and scope. A landing page is cheaper than a corporate site, while an online store or a web app costs more because of integrations. We give a fixed estimate after a short brief and a free consultation; price benchmarks are in our blog.

How long does a project take?

A landing page usually takes 1–3 weeks, a corporate site 3–6 weeks, an online store or SaaS from 6 weeks. Exact timelines are agreed and fixed in the contract once the scope is clarified.

In which languages do you build websites?

We build multilingual websites — Russian, English, Ukrainian and other languages — with correct hreflang markup, separate URLs and translated meta tags, so each language version is indexed correctly by search engines.
