Pages are rendered on the server or generated in advance, so they load fast on mobile too. A faster page means fewer visitors leaving and, in an online store, more purchases.
Opus Online is a Tallinn-based software development company building fast websites, headless online stores and B2B portals with Next.js. Our team of more than 25 people has worked with Next.js for more than 3 years.
We don’t start from the technology but from your goal. First, we find out whether Next.js is the right choice for your project.
Next.js is a React-based framework for building anything from a fast marketing site to a complex web application. For a business, that means three things.
Pages are rendered on the server or generated in advance, so they load fast on mobile too. A faster page means fewer visitors leaving and, in an online store, more purchases.
Search engines and AI assistants see the content right away. Next.js lays a good foundation for meeting the Core Web Vitals requirements, but careful development is what delivers the result.
In a headless architecture, the content management system, e-commerce platform or ERP can be replaced later without rebuilding the whole site.
High-traffic news portals where every article is fast and visible in search from the start. Payload CMS, Strapi, Directus.
A Next.js frontend together with Magento, Adobe Commerce or MedusaJS.
Customer-specific prices, repeat orders, stock levels and ERP integrations.
Public platforms with large amounts of data, fast search and filters.
Applications with sign-in, roles and payments that grow with your business.
Audit, version upgrades and maintenance for a solution built by another team.
We have extensive experience in developing IT software and e-commerce solutions for businesses, spanning from the financial sector to insurance and pharmaceutical industries. We serve as a long-term partner for both large corporations and rapidly growing startups.

Äripäev introduced its new website on 26 June 2024. In the article, the media house describes in its own words what the update changed.
Next.js isn’t right for every project, and we say so honestly at the very first meeting. For a small information site, WordPress is often cheaper and faster to launch.
| Feature | Next.js (headless) | WordPress | Off-the-shelf e-commerce platform |
|---|---|---|---|
| Best suited for | high-traffic sites, online stores, portals | information and marketing sites | online stores with a standard workflow |
| Speed | very good | good, depends on plugins | good |
| Integrations (ERP, PIM, CRM) | unlimited | limited | moderate |
| Design freedom | complete | within the theme | within the theme |
| Initial budget | higher | lower | lower |
| Further development over the years | easy | more complex | within the platform’s limits |
| Editing content | with a CMS (Payload, Strapi, Directus) | built in | built in |
We take over projects built by another agency or an in-house team. We start with a code and security audit that shows you what is in order, what needs fixing and what is critical.
After the takeover, we keep looking after the solution: monitoring, security updates and hosting are part of our maintenance service.
You deal directly with the people who build your solution, not with intermediaries.
We listen to your goals and tell you honestly whether Next.js is a good fit.
Functionality, integrations, risks, timeline and budget.
A working version every couple of weeks.
Speed, accessibility (WCAG, EAA) and security (OWASP).
We stay with the solution after launch too.
Technologies:
A Next.js project usually costs between €10,000 and €70,000. A smaller project may cost less and a large platform more, as the price depends on the specifics of the project. We give an exact estimate after a short analysis.
Usually 1–6 months; a larger project may take longer.
WordPress suits simpler sites; Next.js is the choice when speed, integrations and design freedom matter.
Yes. Content is rendered on the server, so Google and AI search see the page right away.
Yes. We start with a code and security audit and propose a plan for what comes next.
On AWS or Zone, depending on the load and your requirements.
