WordPress websites and online stores – all from one studio.

From WordPress development and WooCommerce stores to SEO and ongoing maintenance – we help small businesses get found and get more out of WordPress.

01

WordPress development

Custom themes and plugins, built light and fast – without bloated page builders and forty plugins. Just clean code that loads fast and is easy for you to manage. See what our WordPress website involves, and read how a website gets built and priced at massruum.

  • Custom theme and block development
  • Carefully chosen, minimal plugins
  • Speed and security hardening
  • Ongoing maintenance packages

02

WooCommerce development

Stores that are a pleasure to buy from and easy to manage. We build new stores and rescue existing ones – cart, payments, orders and product UX that genuinely sell. See the online store service →

  • New stores and store migration
  • Cart and payment optimisation
  • Subscriptions and memberships
  • Stock and fulfilment workflows

03

UX & design

We design around how people actually use your site. Clear structure, considered journeys and an interface that turns first-time visitors into customers.

  • Information architecture and journeys
  • Conversion-focused page design
  • Design systems in Penpot
  • Accessible, responsive layouts

04

Takeover & maintenance

Inherited a messy or slow site? We take over existing WordPress and WooCommerce projects, fix the bugs and keep them fast, secure and current – so you do not have to worry about it. See the takeover service →

  • Audit and rescue of existing sites
  • Speed and security clean-up
  • Updates, backups and monitoring
  • Store maintenance with real people

05

Speed & performance

A slow site loses clients and falls behind in search. We measure where the time goes, fix the highest-impact things first, and show the result in numbers – before and after. Our own site loads in 0.4 s on desktop, Lighthouse 100/100 (measured 13.08.2026). See the speed service →

  • Speed audit: measurement, causes, priorities
  • Images, scripts, caching and redirects sorted out
  • Core Web Vitals and Lighthouse, not a gut feeling
  • Before-and-after numbers, from €400

06

SEO & growth

A beautiful site nobody finds is not doing its job. We build on strong technical SEO, fast load times and clear structured content so the right clients find you in Google. See the SEO service → The monthly work and the report are in the monthly SEO service from €199 a month – see a sample report. What SEO optimisation actually is, and where to start, is a separate guide.

  • Technical SEO and site structure
  • Core Web Vitals and speed
  • Structured data and metadata
  • Content and growth guidance

07

AI-assisted development

We develop with AI assistance and write clean, vanilla WordPress code – faster and more precisely. You get corporate-grade quality at a small-business price: an ultra-fast, flexible, easy-to-maintain site.

  • AI-assisted development, hand-finished code
  • Clean vanilla WordPress, no bloat
  • Corporate quality, small-business price
  • Fast, flexible and easy to extend

Common questions

What clients ask us most.

Both. We build new WordPress and WooCommerce sites from scratch and also take over existing projects – auditing, fixing and modernising what is already there.

They add weight that slows the site and makes it harder to maintain. We build lightweight custom themes and Gutenberg blocks so the site stays fast and easy to manage.

A focused marketing site usually takes a few weeks; a WooCommerce store depends on scope. We agree a clear timeline in the discovery phase, before writing a line of code.

Yes. Maintenance packages cover updates, backups, monitoring and security – done by real people so you do not have to think about it. See pricing.

We build on strong technical SEO – fast load times, clean structure and correct metadata – and advise on content and growth so the right clients find you. See the SEO service.

A website starts from 900 euros and a WooCommerce store from 1900 euros. The final price depends on scope. See the full pricing, read our in-depth 2026 website pricing guide, or ask for a quote.

WordPress is the most widely used website platform and WooCommerce its most flexible store solution. We build both with clean code – fast, secure and yours to manage. You get a store that is easy to extend and a site that does not stagnate over the years.

Before you sign anything, get clear answers to these:

  • Who owns the code, domain, hosting and accounts at the end? They should be in your name, with the logins in your hands.
  • Is the site built with a page builder or with clean code? A builder makes the site heavier and ties you to one tool (why we don’t use them).
  • What happens after launch? Ask who does the updates and backups, and what you get to take with you if you ever change partners.
  • Ask to see real sites that are live today, and check their speed yourself, for example with Google PageSpeed Insights.
  • Who writes the copy? Many developers assume the content comes from the client. Settle that early.
  • Is the scope in writing? The pages, the features and what the quote does not include should be on paper before the work begins.

You can see sites we have built on our work page.

How we work

A clear path from start to launch.

01

Discovery

We get to know your business, goals and what is not working today.

02

Design

We map the UX and design the pages – approved before the first line of code.

03

Build

Clean, fast WordPress/WooCommerce, built to match the design exactly.

04

Launch & maintain

We launch, monitor and keep everything running.

Web development

Web development, and what it means here

Web development here means a hand-written WordPress theme, not a page builder and a stack of plugins. The same holds for a website and an online store: same codebase, same speed, same structure. The difference is what you are left holding – a site whose parts are all yours, and which can keep being developed for years without starting over.

  • A custom theme. The design comes from your brand rather than a template, and the code is only what the site actually needs.
  • Content stays under your control. Every word and image sits in Gutenberg blocks, so changing them does not require us.
  • Speed and SEO are built in. Core Web Vitals, structured data and indexability are part of the build, not a later add-on.
  • Existing sites too. If the site already exists and needs rescuing, we take it over and put it right.
