Summarize this article with:
If your web application is still running on Nuxt 2, you are operating on borrowed time. The framework hit end of life in mid-2024, which means no more patches, no security updates, and a shrinking pool of compatible third-party packages. Meanwhile, Nuxt 3 — rebuilt on top of Vue 3, Vite, and the Nitro server engine — has become the production standard for serious Vue-based projects.
The gap between Nuxt 2 and Nuxt 3 is not a gentle upgrade path. It is a full rewrite of the underlying architecture. Vue 2 components written with the Options API need to be converted to the Composition API. Vuex stores need to be replaced with Pinia. Many popular Nuxt 2 modules simply do not exist in Nuxt 3 and must be rebuilt or swapped out entirely. Configuration files, middleware, plugins, server routes, and rendering strategies all follow different patterns. For applications with dozens of pages and complex business logic, attempting this without experienced help is risky and slow.
The companies listed below have proven track records in handling exactly this kind of work. They understand not just Vue.js in general, but the specific challenges that come with moving a real production codebase from Nuxt 2 to Nuxt 3.
1. Epicmax
Epicmax has been working exclusively with Vue.js and Nuxt since 2017, and their migration practice is one of the most focused in the industry. They offer a dedicated service to help businesses upgrade Nuxt 2 to 3, covering everything from the initial codebase audit to post-launch monitoring. Their process begins with a detailed review of your existing application — mapping out every dependency, module, plugin, and custom integration — so the migration roadmap is based on reality rather than assumptions.
The company has delivered over 60 commercial projects and is deeply embedded in the Vue open-source ecosystem. Epicmax created Vuestic UI, a Vue 3 component framework with more than 17,000 GitHub stars, and holds official partnerships with Vuetify, PrimeVue, Nuxt, and VueJobs. That level of involvement means their developers encounter edge cases and framework internals that most agencies never touch, which translates directly into smoother migrations with fewer surprises.
On the technical side, their migration scope includes refactoring components to the Composition API, converting Vuex state management to Pinia, replacing or rebuilding incompatible Nuxt 2 modules, setting up Nitro server configuration, optimizing rendering strategies, and running comprehensive test suites at each phase. They also invest in knowledge transfer — making sure your in-house developers understand the new architecture and can work with it confidently after handoff. Epicmax serves clients in SaaS, EdTech, fintech, insurance, and e-commerce, with flexible engagement options including dedicated teams, fixed-scope delivery, and standalone consulting.
2. Monterail
Monterail is a Polish development company and official Vue.js and Nuxt partner with close to a decade of experience in the ecosystem. Their engineers have contributed to Vue core tools, and in 2023 the company ran dedicated technical panels on Vue 2 to Vue 3 migration, sharing practical lessons from enterprise-scale projects. They also co-authored the State of Vue 2025 report alongside the Vue and Nuxt core teams.
Their migration methodology is incremental. Instead of shutting down development to rewrite everything at once, Monterail breaks the transition into isolated phases — updating self-contained sections of the application while the rest continues to run on the existing stack. This approach lowers risk, keeps the product usable for end users throughout the process, and allows the team to ship regular feature work in parallel. They also bring strong CI/CD integration expertise, which helps larger teams automate testing and deployment during the migration window.
3. Scandiweb
Scandiweb specializes in high-performance web applications, with particular strength in e-commerce and content-heavy platforms. Their migration experience includes moving complex storefronts and publishing systems from Nuxt 2 to Nuxt 3, often in combination with headless CMS backends and microservices architectures.
For businesses where SEO and page speed directly affect revenue, Scandiweb pays close attention to preserving search rankings and optimizing Core Web Vitals throughout the migration. They audit existing rendering configurations, plan the transition to Nuxt 3’s hybrid SSR and SSG capabilities, and monitor performance metrics before and after launch to catch any regressions. Their post-migration support includes performance tuning and infrastructure optimization to make sure the Nuxt 3 application runs at its full potential.
4. Uptech
Uptech is a product development studio that works primarily with startups and mid-stage companies looking to modernize their tech stacks. Their Nuxt migration work is tightly integrated with their broader product development process, which means they think about the migration not just as a code conversion exercise but as an opportunity to improve the overall product architecture.
They break migrations into small, deployable increments and validate each one against real usage data. This makes them a good fit for products that cannot tolerate extended feature freezes or that need to keep iterating on the user experience during the transition period. Uptech also focuses on structuring the migrated codebase for long-term developer productivity — applying consistent patterns, removing accumulated technical debt, and documenting architectural decisions so future team members can ramp up quickly.
5. NuxtLabs
NuxtLabs is the organization behind the Nuxt framework. While their primary focus is building and maintaining the open-source project, they also provide consulting and architecture audit services for companies navigating complex migrations. Working with NuxtLabs means getting guidance from the people who designed the system you are migrating to.
Their engagements are typically advisory — reviewing your migration plan, identifying architectural risks, recommending module replacements, and optimizing your rendering and deployment strategy. For companies with strong in-house engineering teams that just need expert-level direction, NuxtLabs offers the most authoritative perspective available. They previously guided a Fortune 50 SaaS company through a Nuxt 2 to Nuxt 3 transition that reduced bundle size by over 30 percent and enabled edge-rendering deployment. NuxtLabs was recently acquired by Vercel but continues to operate the Nuxt project independently with a commitment to keeping it open-source and host-agnostic.
Why Waiting Makes the Migration Harder
Every month you stay on Nuxt 2, the migration gets more expensive. Dependencies drift further from compatibility with modern tooling. New developers joining your team have to learn patterns and APIs that the broader community has moved away from. Security vulnerabilities discovered in Vue 2 or Nuxt 2 will never be patched. And when the migration does finally happen, the gap between your codebase and current best practices will be wider, meaning more code to rewrite and more regressions to hunt down.
On the other side, Nuxt 3 applications benefit from Vite’s dramatically faster build times, Vue 3’s optimized reactivity engine, smaller production bundles, first-class TypeScript support, and the Nitro server engine’s flexibility to deploy anywhere — from traditional servers to edge networks. Pinia offers a cleaner, more type-safe state management experience than Vuex. The Composition API produces more reusable, testable code. These are not incremental improvements; they represent a generational leap in what the framework can do.
Picking the Right Migration Partner
When choosing a company to handle your Nuxt migration, look for specific experience — not just general Vue.js development, but actual Nuxt 2 to Nuxt 3 transition projects. Ask for case studies. Check whether they contribute to the Nuxt ecosystem or hold partnerships within it. A company that starts with a codebase audit before quoting timelines is a company that understands the complexity involved.
Consider what your team needs most. If you want a full-service partner that handles everything from planning to deployment, Epicmax or Monterail are strong choices. If your team is capable but needs expert guidance on strategy and architecture, NuxtLabs is the obvious option. If your product is in e-commerce and SEO preservation is critical, Scandiweb has relevant domain experience. And if you want a partner that integrates migration work into ongoing product development, Uptech’s iterative approach may be the best fit. Whichever company you choose, the most important decision is not to delay the migration any longer than necessary.
