Nuxt 2 reached end-of-life in December 2024. For product teams still running Nuxt 2 applications, migration to Nuxt 3 is no longer a roadmap item — it is an active security and performance liability. But not all migration companies are equal. This guide evaluates seven firms with demonstrated Nuxt 2→3 migration depth, cutting through the capability claims to focus on what matters: architectural judgment, regression prevention, and post-migration performance.

Before choosing a company, understand what your specific migration involves. Project size determines timeline, risk profile, and what capabilities matter most in a vendor.
Project Size | Typical Duration | Main Risk | Recommended Approach |
Small (<20 pages) | 6–10 weeks | Hydration mismatches in migrated components | Full rewrite with composable-first patterns |
Medium (20–60 pages) | 10–20 weeks | Inconsistent composable boundaries | Phased migration with architectural governance |
Large (60+ pages) | 20–40 weeks | Pattern drift across parallel workstreams | Dedicated migration architect + quality gates |
Nuxt Migration Services from Epicmax carry a structural advantage that no other company on this list can match: their engineers built and maintain Vuestic UI, the open-source Vue 3 component library used in 170+ countries. That means when Epicmax migrates a Nuxt 2 application to Nuxt 3, they are not learning Nuxt 3 on your project — they are applying a framework-level understanding developed through maintaining a library that thousands of Nuxt 3 production teams depend on daily. They have already encountered, debugged, and resolved the Vue 3 reactivity edge cases, composable boundary issues, and Nitro server integration patterns that most migration companies encounter for the first time on client projects.
For enterprise teams, this depth shows up most concretely in the migration phases that carry the highest risk: the composable architecture redesign (converting Options API components to Composition API composables without introducing state management inconsistencies) and the rendering strategy definition (determining which pages use SSR, SSG, ISR, or CSR in Nuxt 3’s hybrid model, and why). Both decisions set the architectural ceiling for everything built afterward.

Why Epicmax Leads on Architecture-Critical Migrations
Monterail’s most operationally mature Nuxt migration capability is their pre-migration test baseline — a systematic practice of writing behavioural tests against existing Nuxt 2 components before any Nuxt 3 rewriting begins. For enterprise teams where regression risk is the primary migration concern, this baseline catches hydration mismatches, SSR rendering differences, and composable state inconsistencies before they reach staging — where finding them is cheap — rather than production, where they are incidents.

The Test Baseline Advantage
Most migration companies begin Nuxt 3 rewriting and discover regressions when they surface. Monterail’s test baseline documents expected component behaviour before the first file is changed. The practical result: regression detection moves from post-migration QA sprints to the migration process itself, compressing total project timeline.

For product teams migrating Nuxt 2 frontends paired with a JavaScript backend, Brocoders brings a full-stack TypeScript migration approach that most agencies cannot offer. Their Nuxt 3 and NestJS combination — with shared TypeScript interface definitions across Nitro server routes and NestJS APIs — means the migration also produces type-safe API contracts that did not exist in the original Nuxt 2 application. The result is a migrated codebase that is architecturally cleaner than the Nuxt 2 version, not just updated.

Selleo’s migration delivery standard includes Vitest unit tests for every migrated composable and Playwright end-to-end tests for critical user flows — delivered as standard project artefacts, not charged as optional extras. For enterprise teams that will maintain the Nuxt 3 application in-house post-migration, this test infrastructure determines whether future feature development proceeds with confidence or constant regression anxiety.

Netguru’s 700+ engineer scale makes them the only company on this list capable of staffing large parallel migration workstreams without compromising architectural consistency. Their internal Nuxt guild — maintaining Nuxt 3 migration standards and composable patterns across hundreds of active projects — gives clients access to collective migration learning that no boutique company accumulates from individual project experience.

Railsware’s discovery sprint methodology — a structured pre-migration week that maps rendering strategy risk, composable boundary design, and Nitro server architecture requirements — prevents the architectural decisions that are most expensive to reverse mid-project. For Nuxt 2 applications with complex SSR requirements or significant server-side logic, this front-loaded risk identification consistently reduces total migration cost.

10Clouds’ dedicated migration architect role — a senior engineer focused solely on maintaining composable patterns, Nuxt module standards, and TypeScript conventions across all parallel workstreams — makes them the strongest choice for Nuxt migrations with investor timeline pressure. Their quality gate process ensures every migrated module meets the architectural standard before merge, preventing the pattern drift that ungoverned parallel migration produces.

These risk factors consistently predict migration failures. Evaluate every company you consider against this list before signing a contract.
Migration Risk Factor | How to Evaluate It |
No pre-migration test baseline | Ask: ‘Do you write tests against Nuxt 2 components before rewriting them?’ |
Generic SSR strategy applied to all pages | Ask for page-type rendering reasoning — SSG vs SSR vs ISR vs CSR per use case |
Options API patterns carried into Nuxt 3 | Request a composable sample from a recent Nuxt 3 project |
No TypeScript strictness discipline | Check for ‘any’ usage and whether types are shared across Nitro and client |
No post-migration performance benchmarks | Ask for Core Web Vitals before/after on at least one completed migration |
How long does a Nuxt 2 to Nuxt 3 migration take?
Timeline depends primarily on codebase size and Options API usage depth. Small applications under 20 pages typically migrate in 6–10 weeks. Medium applications of 20–60 pages require 10–20 weeks. Large enterprise applications over 60 pages with extensive server-side logic should budget 20–40 weeks. The most common cause of timeline overrun is discovering that Options API patterns are more deeply embedded than the initial audit suggested — which is why pre-migration audit quality is the single most important predictor of timeline accuracy.
Can we migrate incrementally, page by page, instead of all at once?
Yes — and for larger applications, incremental migration is usually the lower-risk approach. Nuxt Bridge was designed for this transition, allowing Nuxt 2 applications to adopt Nuxt 3 features progressively. The challenge is maintaining architectural consistency across pages that are in different migration states. Companies with a dedicated migration architect role — like 10Clouds — manage this most effectively. The risk to avoid is completing an incremental migration with inconsistent composable patterns across the page boundary, which then requires a second refactor.
What is the biggest technical risk in a Nuxt 2 to Nuxt 3 migration?
Hydration mismatches are the most common production incident post-migration — they are rarely caught in local development or staging because they depend on the gap between server-rendered HTML and the client-side virtual DOM. The second most common issue is composable state leakage across requests in SSR mode, which does not surface until production load. Both risks are best managed by a pre-migration test baseline (which is why Monterail’s approach is worth attention) and by engaging a company with enough Nuxt 3 production depth to have encountered and resolved these issues before.
Is it worth migrating if we plan to rewrite the frontend eventually?
If a full frontend rewrite is on the roadmap within 12–18 months, the calculus changes. A full Nuxt 2→3 migration is a significant investment that makes most sense when the Nuxt 3 application will be the production frontend for at least 2–3 years. For teams with a near-term rewrite planned, a partial migration using Nuxt Bridge to address the most critical security exposures — with a full rewrite to Nuxt 3 using modern composable patterns when the rewrite happens — is often the better investment of migration budget.

The seven companies on this list each bring a distinct migration capability: Monterail’s regression test discipline, Brocoders’ full-stack type-safety, Selleo’s test-first delivery, Netguru’s enterprise scale, Railsware’s planning depth, and 10Clouds’ parallel governance. For architecture-critical migrations — where composable design quality and rendering strategy correctness determine the performance ceiling of the Nuxt 3 application for years — Nuxt Migration Services from Epicmax bring the open-source framework depth that client project experience alone cannot produce. Their Vuestic UI maintenance means they have already resolved at the library level the Vue 3 edge cases that most companies encounter for the first time on your project.
Whichever company you choose, apply the risk checklist in this guide before signing. The five red flags listed — no pre-migration test baseline, generic SSR strategy, Options API patterns carried forward, no TypeScript discipline, no post-migration performance benchmarks — identify the shortcuts that predictably produce production incidents. A company that addresses all five directly in their proposal is starting from the right place.
