Best Next.js agencies for SaaS builds, scored

On public evidence, the best Next.js agencies for a SaaS build right now are Pagepro and FocusReactive. Both show named, logged-in products built in Next.js, many Next.js projects, and over 25 independent reviews. Brainhub, Bejamas, and Blazity come next, and Blazity is the strongest pick if you want an agency Vercel itself rates highly.

We wrote this guide, so weigh that. We left ourselves out of the ranking. Where we fit is in a box at the end.

Who this is for: a founder or product lead who needs a SaaS web app built or rebuilt in Next.js by an outside team. Who should look elsewhere: if you need a marketing site only, most agencies here do that too, but a site builder or an Astro build may cost less. Our Next.js or Astro post explains the split. If you’ve picked SvelteKit instead, see the SvelteKit agencies with real Svelte work.

We read the lists that rank for “best Next.js agency” before writing this one: GitNation, Pagepro, DesignRevision, and PandaCodeGen. Several are written by agencies that rank themselves, and none of them says which entries have shipped a logged-in app rather than a marketing site. For a SaaS build, that’s the question that matters, so it’s the first row of our rubric.

How we scored them

Each agency gets 0, 1, or 2 points on five criteria, for a total out of 10. We only counted what we could open on a public page on 2026-10-13 and 2026-10-14. A low score means we found little public evidence. It doesn’t mean the work is bad. A lot of SaaS work sits under NDA.

Ties are ordered by the named-app score, then by review count. The Vercel tiers come from Vercel’s solution partner directory, which listed 115 agencies in four tiers when we checked on 2026-10-14.

The scores at a glance

What the live sites ship

The topic needed a performance check, so we loaded the live, named Next.js sites from the case studies above. We ran each homepage three times in headless Chrome on 2026-10-14 with the cache off and took the middle run. The numbers are compressed bytes over the wire, measured by us.

We didn’t score this table, for two reasons. A live site today carries whatever the client added after handover, such as chat widgets, A/B tests, and analytics. And a homepage is a different job from a logged-in app. Rippling’s homepage is a large marketing site, and the others are smaller. Read it as a prompt to ask each agency what its own budget for JavaScript is. We tried to add PageSpeed Insights scores, but the public API returned “Quota exceeded” on 2026-10-14.

1. Pagepro: best for a Next.js SaaS rebuild with a fixed team

• Named app (2): a Clutch review from Learn Squared, an online learning business, describes moving its platform “from Drupal to Next.js” with AWS, PostgreSQL, Strapi, and a Shopify integration. That’s a store and a course platform with accounts.
• Projects (2): four Clutch reviews name Next.js: Learn Squared, OmniaMed’s GP Notebook, Localcoin, and a Sanity and Next.js site for a digital agency.
• Vercel or depth (1): not in Vercel’s directory when we checked. Pagepro publishes a lot on Next.js, including its own list of Next.js agencies.
• Budget (1): $25,000+ minimum and $50 to $99 an hour on Clutch.
• Reviews (2): 4.9 from 32 reviews on Clutch, checked 2026-10-14. One reviewer noted the project ran over the estimated timeline, which is the kind of detail worth reading.

Pick them for a migration onto Next.js with a database and a store attached, with a budget of $25,000 or more. Their case studies page returned HTTP 403 to our tools, so we scored them from Clutch.

2. FocusReactive: best for content-heavy SaaS with a headless CMS

• Named app (2): for Porchlight Real Estate Group, they replaced an “Outdated PHP based platform” with “a modern, scalable platform on Next.js” and PostgreSQL, with maps covering “1K+ geo areas” and PDF market reports for agents (case study).
• Projects (2): their case studies page names Next.js on 20 of the 31 projects shown, including EmailOctopus, an email marketing SaaS whose site moved from WordPress to Payload and Next.js.
• Vercel or depth (1): Silver in Vercel’s directory.
• Budget (1): $10,000+ minimum on Clutch. Their contact form offers budget bands from €5,000 to €100,000+, which isn’t a price.
• Reviews (2): 4.9 from 28 reviews on Clutch, $50 to $99 an hour, based in Amsterdam.

Pick them if your SaaS has a big public site and an editorial team as well as the app. Most of their work is CMS and marketing platforms, so ask for app references.

3. Brainhub: best for a product rewrite with an embedded team

• Named app (2): for RapidPipeline, a 3D asset platform, Brainhub rewrote the frontend with the stack “Next.js, Next Auth, Mantine, React Query, GrowthBook”, including “User account management (notifications, payments, etc.)” (case study).
• Projects (1): on their case studies page, one other card is tagged Next.js, an unnamed networking platform. Most of their work is React, Node.js, and Electron.
• Vercel or depth (1): not in Vercel’s directory. They publish React and Next.js guides.
• Budget (1): $50,000+ minimum on Clutch, $50 to $99 an hour.
• Reviews (2): 4.9 from 53 reviews on Clutch, the most of any agency on this list after Netguru and STRV.

Pick them for a larger rewrite where their engineers work beside yours. The minimum rules out small MVPs.

4. Bejamas: best for a fast marketing site in front of your SaaS

• Named app (1): their work page lists 34 projects, and the Next.js ones are marketing sites and replatforms. For Rippling, they rebuilt the marketing site on “Contentful (headless CMS), Next.js, and Algolia”. We found no logged-in app.
• Projects (2): 18 of those 34 projects name Next.js, including RudderStack, Descope, Rearc, and HTTP Toolkit.
• Vercel or depth (1): Silver in Vercel’s directory.
• Budget (1): $10,000+ minimum on Clutch, $50 to $99 an hour.
• Reviews (2): 4.9 from 28 reviews on Clutch, based in Wrocław, Poland.

Pick them for the public site that sells your SaaS, not the app behind the login.

5. Blazity: best when you want Vercel’s own top-tier partner

• Named app (1): for CookUnity, a meal subscription business, they did a “complete migration from React.js with Redux to Next.js in 3 months” of the subscription funnel and report a “70% LCP improvement” (case study). That’s Blazity’s own number, and the page gives no baseline. A signup funnel is close to an app, but it isn’t the logged-in product.
• Projects (1): two of nine cards on their case studies page name Next.js: CookUnity and Iberion.
• Vercel or depth (2): Gold in Vercel’s directory, the only agency on this list above Silver.
• Budget (1): $10,000+ minimum on Clutch, $50 to $99 an hour.
• Reviews (2): 5.0 from 27 reviews on Clutch, a team of 10 to 49 in Warsaw.

Pick them for performance work or a migration onto Next.js where Core Web Vitals drive revenue. We tried to load cookunity.com for the table above and got a bot check, so we couldn’t measure it.

6. Netguru: best for a large team across web and mobile

• Named app (0): their Next.js page names Spacefox and VisionHealth, but ties neither to Next.js. VisionHealth’s app was built “using React Native with TypeScript”.
• Projects (0): we found no named client tied to Next.js.
• Vercel or depth (1): not in Vercel’s directory. They publish a lot of Next.js writing.
• Budget (1): $50,000+ minimum on Clutch, $50 to $99 an hour.
• Reviews (2): 4.8 from 73 reviews on Clutch, the most on this list. A team of 250 to 999 in Poznań, Poland.

Pick them when you need many people and many platforms. Ask for Next.js references before you sign.

7. STRV: best for a product with web, iOS, and Android at once

• Named app (0): they built Nav’s banking web app, which passed “more than 5,000 accounts” in its first months (case study). The page doesn’t name a framework, so it doesn’t count here.
• Projects (0): no named project says Next.js. Their own site runs on Next.js.
• Vercel or depth (1): Enrolled in Vercel’s directory.
• Budget (1): $100,000+ minimum on Clutch, $100 to $149 an hour.
• Reviews (2): 4.8 from 60 reviews on Clutch. Prague and San Francisco.

Pick them for a well-funded product that launches on web and mobile together.

Checked and left off

• This Dot Labs is a Vercel Silver partner with real SaaS work on its case studies page, such as Sentry’s session replay feature, but none of its case studies names Next.js, and we found no Clutch profile.
• Increasio, Codeable, StaticMania, and eSEOspace appear on other lists. The last three rank themselves first on their own lists, and we found no named Next.js SaaS app for any of them.
• Large Platinum partners in Vercel’s directory, such as Valtech and Perficient, build for enterprises. We left them off because their minimums and processes don’t fit most SaaS founders.

How to choose a Next.js agency for a SaaS build

1. Ask for a logged-in app, not a homepage. A fast marketing site proves less than an app with auth, billing, roles, and a database. Ask for a demo account or a screen share.
2. Ask how they split server and client code. You want a specific answer about Server Components, Server Actions, and route handlers. Our Server Actions or API routes post covers what a good answer sounds like.
3. Ask how tenants are kept apart. Row-level, schema, or database isolation each change your cost and your risk. See multi-tenant isolation models.
4. Ask where it will run. Next.js runs on Vercel, on Node servers, and on other hosts. Make sure you can move if prices change.
5. Ask for their JavaScript budget. The table above shows about a 4x spread in JavaScript between live sites. A good agency has a number and checks it.
6. Check the minimum before the call. Clutch minimums here run from $10,000 to $100,000+.
7. Read reviews for overruns and changes, not stars. Every rated agency here sits between 4.8 and 5.0. Our guide to vetting an offshore team lists what to look for.

Who should pick whom

FAQ

How much does a Next.js agency charge for a SaaS build?

Clutch minimums on this list run from $10,000 (Blazity, Bejamas, FocusReactive) to $100,000+ (STRV), with hourly rates of $50 to $149, checked 2026-10-14. None of the seven publishes a full project price on its own site.

Is a Vercel partner better than an agency that isn’t one?

Not by itself. Vercel’s directory tells you an agency has a relationship with Vercel and some volume of work. It doesn’t tell you whether it has built a logged-in app. Two of our top three aren’t in the directory.

Should a SaaS be built in Next.js?

It’s a sound default if you want one React codebase for the public site and the app. If the public side is mostly content, a separate Astro site can be lighter. Our Next.js or Astro post compares both from two live builds.

Can a Next.js agency take over an existing codebase?

Yes, and most of the work on this list is exactly that: Pagepro moved Learn Squared off Drupal, FocusReactive replaced a PHP platform, and Blazity moved CookUnity off a client-side React app. Ask for a paid code review first, so you see how they read someone else’s code before you commit to a rebuild.
