If you've been researching headless CMS migration agencies, you've almost certainly come across FocusReactive. They've built a solid reputation in the headless space -- particularly around Sanity, Contentful, and Next.js projects. But here's the thing: they're not the only shop doing this work, and depending on your project scope, budget, and tech stack preferences, they might not be the best fit.

I've spent the better part of six years working on headless CMS migrations -- moving teams off WordPress, Drupal, and legacy monoliths into modern content architectures. I've seen agencies nail it and I've seen agencies burn through six figures before delivering anything usable. This article is the comparison I wish existed when I was evaluating partners for my own projects.

FocusReactive Alternatives: Headless CMS Migration Agencies in 2026

Why You're Looking for a FocusReactive Alternative

Let's be honest about the reasons people look for alternatives. It's usually one of these:

  1. Budget mismatch. FocusReactive is a premium agency. Their rates reflect a team with deep expertise, but not every project needs (or can afford) $200-350/hour rates.
  2. Tech stack preferences. FocusReactive leans heavily into Sanity and Next.js. If you're committed to Contentful, Strapi, Payload CMS, or want to build on Astro, you might want a team with deeper expertise in those specific tools.
  3. Availability. Good agencies are booked out. In 2026, demand for headless migrations has only increased, and lead times of 2-3 months before kickoff aren't unusual.
  4. Geographic or timezone needs. Sometimes you need overlap with your team's working hours, and that narrows the field.
  5. Project scope. Maybe your migration is smaller than what FocusReactive typically takes on, or maybe it's so large you need a bigger team.

None of these reasons mean FocusReactive is bad. They're just practical constraints that shape which agency is right for your situation.

FocusReactive: What They Do Well and Where They Fall Short

Strengths

FocusReactive has been in the headless space since before it was trendy. They have genuine production experience with Sanity Studio customization, and their work with Next.js App Router patterns is solid. They've contributed to open-source tooling around Sanity, which tells you something about the depth of their knowledge.

Their team understands content modeling -- not just the code side, but the editorial experience side. That matters more than most technical teams realize. A migration that makes developers happy but makes content editors miserable is a failed migration.

Where They May Not Be the Best Fit

  • Pricing transparency. Like most premium agencies, you won't find pricing on their website. Expect $150K+ for a full migration project.
  • Sanity-centric. If you're not going to Sanity, you're not getting their A-game. That's not a criticism -- specialization is a feature -- but it's worth knowing.
  • Scaling limitations. As a boutique shop, they can struggle to staff multiple concurrent workstreams on very large enterprise migrations.
  • Limited Astro experience. If you're looking at Astro for content-heavy sites (and in 2026, you probably should be), FocusReactive hasn't been as vocal or visible in that ecosystem.

Top FocusReactive Alternatives for Headless CMS Migration in 2026

Social Animal

Full disclosure: this is us. But I'll give you the same honest assessment I'm giving everyone else.

Social Animal is a headless web development agency that specializes in Next.js development and Astro development, with deep experience in headless CMS migrations. We're CMS-agnostic -- we've done production migrations involving Sanity, Contentful, Payload CMS, Strapi, Storyblok, and Hygraph.

Our sweet spot is mid-market companies doing their first headless migration, or teams moving between headless CMS platforms (Contentful to Sanity, for example). We're particularly strong on content modeling strategy and building migration tooling that handles messy real-world data -- not the clean demo data you see in tutorials.

Pricing starts around $25K for smaller migrations and scales with complexity. You can check our pricing page for current rates, or reach out directly if you want to talk specifics.

Bejamas

Bejamas has been a staple in the Jamstack/headless world for years. They've evolved their positioning from "Jamstack agency" to a broader headless commerce and content platform consultancy. Their strength is in performance optimization -- they're obsessive about Core Web Vitals, and their migration projects tend to deliver measurable speed improvements.

They work across multiple CMS platforms and have solid Shopify Hydrogen experience if your migration involves commerce. Pricing is comparable to FocusReactive -- expect $120K-250K for a full migration.

Sanity.io Professional Services

If you're definitely going to Sanity, their own professional services team is worth considering. They obviously know the platform better than anyone, and since 2025 they've expanded their services team significantly. The downside? They're not going to tell you if Sanity isn't the right choice for your use case. And their frontend expertise varies -- you might end up needing a separate agency for the presentation layer anyway.

Typical engagement: $80K-200K depending on scope.

Kin + Carta (formerly Valtech in some markets)

For enterprise-scale migrations -- we're talking 50K+ content items, multi-region, multi-brand -- Kin + Carta has the team size and process maturity to handle it. They're not cheap (enterprise never is -- think $300K-1M+), and their timelines are longer, but they bring program management capabilities that smaller agencies simply can't match.

Not the right choice if you're a Series B startup with 500 pages. Absolutely the right choice if you're a Fortune 500 moving off Adobe Experience Manager.

Stackbit / Netlify Create Team (now part of Netlify)

This is a slightly different category. Netlify's visual editing layer can reduce the need for heavy CMS migration work by providing a composition layer on top of your existing content sources. If your primary pain point is editorial experience rather than the underlying CMS technology, this path might save you from a full migration entirely.

Pricing is platform-based rather than project-based: Netlify's enterprise plans start around $1,500/month.

Uniform.dev

Another "avoid the migration" option. Uniform provides a DXCP (Digital Experience Composition Platform) that can sit in front of multiple CMS instances. If you have content spread across three different systems and don't want to consolidate into one CMS, Uniform lets you compose pages from multiple sources. It's not a traditional agency -- it's a platform with professional services attached.

64robots

64robots is a Laravel and Vue.js shop that's expanded into headless CMS work, particularly with Statamic and Payload CMS. If your backend team is Laravel-heavy and you want to stay in that ecosystem while going headless, they're a strong option. Less experience with React-based frontends, but solid on the API and content management side.

Key Factors When Choosing a Migration Agency

Content Modeling Experience

This is the factor that separates good migrations from bad ones. Any competent developer can move data from point A to point B. The hard part is designing the content model at point B so it actually serves your editorial team's needs for the next 3-5 years.

Ask potential agencies about their content modeling process. If they jump straight to technical implementation without spending significant time understanding your editorial workflows, that's a red flag.

Migration Tooling and Data Pipeline

How does the agency handle the actual data migration? Hand-written scripts? A proprietary migration framework? Do they have experience with your source CMS's API or export format?

Here's a quick example of what a content migration script might look like when moving from WordPress to Sanity:

import { createClient } from '@sanity/client'
import { fetchWordPressPosts } from './wp-api'
import { transformPost, transformMedia } from './transformers'

const sanity = createClient({
  projectId: 'your-project-id',
  dataset: 'production',
  token: process.env.SANITY_WRITE_TOKEN,
  apiVersion: '2026-01-01',
  useCdn: false,
})

async function migrateContent() {
  const wpPosts = await fetchWordPressPosts({ perPage: 100 })
  
  // Phase 1: Migrate media assets first (content references them)
  const mediaMap = new Map()
  for (const post of wpPosts) {
    for (const image of post.embeddedMedia) {
      if (!mediaMap.has(image.id)) {
        const asset = await sanity.assets.upload('image', image.sourceUrl)
        mediaMap.set(image.id, asset._id)
      }
    }
  }

  // Phase 2: Transform and upload content
  const transaction = sanity.transaction()
  for (const post of wpPosts) {
    const sanityDoc = transformPost(post, mediaMap)
    transaction.createOrReplace(sanityDoc)
  }

  await transaction.commit()
  console.log(`Migrated ${wpPosts.length} posts`)
}

This is simplified, obviously. Real migrations deal with broken HTML, inconsistent taxonomies, missing alt text, redirect mapping, and content that hasn't been touched since 2017 but somehow still gets traffic. A good agency has seen all of this before.

Post-Migration Support

What happens after launch? You'll find bugs. Content editors will discover edge cases. Your SEO rankings will fluctuate (they always do after a migration, even a well-executed one). Make sure your agency contract includes post-launch support -- at minimum 30 days, ideally 90.

Redirect Strategy

I've seen migrations destroy organic traffic because nobody planned the redirect strategy properly. This deserves its own conversation during agency evaluation. Ask specifically:

  • How do they audit existing URLs?
  • How do they handle redirect chains from previous migrations?
  • Do they implement redirects at the CDN/edge level or the application level?
  • How do they monitor for 404s post-launch?
// next.config.js - Edge-level redirects for Next.js migrations
module.exports = {
  async redirects() {
    // Import generated redirect map from migration tooling
    const redirectMap = require('./migration/redirect-map.json')
    
    return redirectMap.map(({ source, destination }) => ({
      source,
      destination,
      permanent: true, // 308 status code
    }))
  },
}

Migration Complexity: What Actually Drives Cost

Agencies will quote you based on complexity, but what does that actually mean? Here's what moves the needle on pricing:

Complexity Factor Low Impact High Impact
Content volume < 500 pages 10,000+ pages
Content types 3-5 types 20+ types with nested references
Media assets Text-heavy, few images Thousands of images/videos with metadata
Localizations Single language 10+ locales with translation workflows
Integrations CMS + frontend only CMS + DAM + PIM + search + analytics
URL structure changes 1:1 mapping Complete restructure
Editorial training Tech-savvy team 50+ editors across departments
Compliance Standard HIPAA, GDPR with data residency requirements

The content volume number is deceptive. 10,000 pages of blog posts with a consistent structure is often easier to migrate than 500 pages with 30 different content types, complex relationships, and embedded custom widgets. Always discuss the shape of your content, not just the volume.

Real Migration Timelines in 2026

Here are realistic timelines based on what I've seen across dozens of projects:

  • Simple blog/marketing site (< 200 pages): 6-10 weeks
  • Mid-size content platform (200-2,000 pages): 10-16 weeks
  • Large content platform (2,000-10,000 pages): 16-24 weeks
  • Enterprise multi-site (10,000+ pages, multiple brands): 6-12 months

These assume the agency starts on time. Add 4-8 weeks of pre-work for content audit, stakeholder alignment, and content modeling workshops. And add buffer. Always add buffer. I've never seen a migration come in under the estimated timeline.

The biggest timeline killer? Internal approvals. Your agency can have the migration tooling ready in week 3, but if it takes your legal team 6 weeks to approve the new CMS vendor contract, nothing moves.

When to Go Agency vs. In-House

Not every migration needs an agency. Here's my honest take:

Go in-house if:

  • Your dev team has production experience with the target CMS
  • You have fewer than 200 pages
  • Your content model is straightforward
  • You have 3+ months of dedicated engineering time available
  • You're okay with a longer timeline

Hire an agency if:

  • This is your team's first headless migration
  • You need to maintain the current site while building the new one
  • Content modeling decisions will have long-term architectural impact
  • You have a hard deadline (rebrand, contractual, regulatory)
  • The migration involves complex data transformations

The hybrid approach works well too: hire an agency for content modeling, migration tooling, and architecture decisions, then have your internal team handle the frontend build. We do this kind of engagement regularly at Social Animal -- you can see our headless CMS development services for more on how that works.

FAQ

Is FocusReactive still a good agency in 2026?

Yes. FocusReactive continues to do strong work, particularly in the Sanity ecosystem. They've built real expertise over years of production projects. The question isn't whether they're good -- it's whether they're the right fit for your specific project, budget, and tech stack requirements.

How much does a headless CMS migration cost in 2026?

Budget $25K-50K for a simple marketing site migration, $80K-200K for a mid-size content platform, and $200K-1M+ for enterprise multi-site migrations. These ranges are wide because cost depends heavily on content complexity, number of integrations, and localization requirements. Get at least three quotes.

What's the best headless CMS for migration in 2026?

There's no universal "best." Sanity is excellent for teams that want maximum flexibility and custom editing experiences. Contentful is strong for enterprises that need strict governance and role-based access. Payload CMS has emerged as a top choice for teams that want to own their data and self-host. Storyblok is great if visual editing is a priority. The right CMS depends on your editorial team's needs, your developer team's preferences, and your infrastructure requirements.

How long does a headless CMS migration take?

Plan for 6-10 weeks for a small site, 10-16 weeks for mid-size, and 4-12 months for enterprise. The biggest variable isn't the technical work -- it's internal decision-making, content cleanup, and stakeholder alignment. Start your content audit before you even engage an agency.

Will a CMS migration hurt my SEO rankings?

It can, temporarily. Even with perfect redirect mapping, Google needs time to recrawl and reindex. Most sites see a 2-6 week fluctuation period after migration. The risk increases if URLs change, page speed decreases, or structured data gets lost. A competent migration agency will have a specific SEO migration plan that covers redirects, canonical tags, sitemap updates, and Search Console monitoring.

What should I ask a headless CMS migration agency before hiring them?

Ask for specific examples of migrations similar to yours (source CMS, target CMS, content volume). Ask about their content modeling process. Ask how they handle media asset migration. Ask about their redirect strategy. Ask about post-launch support terms. And ask for a reference from a client whose project was similar in scope to yours. If they can't provide one, that's telling.

Can I migrate from one headless CMS to another (e.g., Contentful to Sanity)?

Absolutely. CMS-to-CMS migrations in the headless world are increasingly common. The content is already API-accessible, which makes extraction easier than migrating from a monolithic CMS. The challenge is usually in the content model differences between platforms and in rebuilding any custom CMS plugins or extensions. Budget 60-70% of what a full legacy-to-headless migration would cost.

Should I migrate my CMS and rebuild my frontend at the same time?

It depends on your risk tolerance. Doing both simultaneously is faster overall but riskier -- more moving parts, harder to debug issues. A phased approach (migrate CMS first with existing frontend, then rebuild frontend) is safer but takes longer and costs more since you're essentially touching the system twice. For most mid-size projects, I recommend the simultaneous approach with a good staging environment and thorough QA process.
