Blazity – Leading Next.js Agency in Poland

Blazity is a Poland-based Next.js development agency (est. 2018) known for its laser focus on modern web technologies. Based in Warsaw yet fully remote, the team has delivered dozens of ambitious projects worldwide using Next.js, React, and Jamstack architectures. Blazity acts as both a consulting partner and development powerhouse – meaning they don't just code, but also guide clients on architecture, performance, and best practices.

As a result, they have become a go-to partner for companies looking to modernize legacy systems or accelerate new product development on the Next.js stack. Blazity's partnerships with industry leaders (Vercel, Contentful, Hygraph) and awards like Deloitte Fast 50 illustrate its standing as a premier Next.js agency in Poland. Whether it's a content-rich corporate site or a dynamic e-commerce app, Blazity brings Polish engineering talent with a global mindset, delivering solutions that “make your brand & product stand out.”

Agency vs. Software House – What is Blazity?

In the tech world, the terms “agency” and “software house” often overlap, and Blazity embodies the strengths of both. As a software house, Blazity provides deep technical expertise in software development (especially Next.js and React), focusing on writing quality code and building robust applications. Like a digital agency, Blazity also offers strategic guidance, UX/UI insight, and close collaboration to ensure the final product aligns with business goals.

In practice, Blazity operates as a technical consultancy with an agency-style full-service approach – they can take over the entire development lifecycle, from ideation and design to deployment and optimization. For clients, this means you get the best of both worlds: rigorous engineering and innovation (software house) combined with consultative partnership and flexibility (agency). The result is a development process that is both highly professional and tailored to your business needs, rather than just a code factory.

Core Web Vitals Expertise Highlights

Blazity has documented expertise in improving Core Web Vitals for enterprise Next.js applications. In one migration project, LCP was reduced from 5.2s to 1.1s. Their Expert Guide to Next.js Performance Optimization is a 90-page reference on real-world performance strategies. Blazity's work has been featured by Vercel and applied to large-scale replatformings, including news media groups and SaaS platforms.
