Greenfield Next.js apps

From idea to solid first version

Most of our Next.js work starts when a product idea needs to become real quickly, without building on throwaway foundations. An AI chat interface. A customer portal. A partner dashboard. A CMS-backed product surface with authentication, permissions and billing logic sitting behind the public site.

We like that stage. The scope is still moving, but the early technical decisions matter: auth shape, data boundaries, caching, AI provider strategy, deployment model, observability, cost controls and where the app should lean on the server instead of pushing everything into the browser.

Our job is to get you to a first version fast, then make sure it is not a dead end. You get something customers can use, investors can understand and your team can keep extending after the first round of feedback.



The parts that make apps feel good



Data-heavy screens

Data-heavy screens

Dashboards, reports, portals and account views need data fetching that is boring in the best way. We keep the heavy work on the server, stream the slow parts, and avoid client-side soup unless the interaction really needs it.

AI product interfaces

AI product interfaces

Chat, generation, review queues, agent workflows, embeddings search, streamed responses and human approval steps. We build the interface around latency, state and failure, not just the happy-path demo.

Content and product together

Content and product together

A SaaS app still needs landing pages, docs, case studies, changelogs and campaign pages. We wire CMS or MDX content into the same design system so the public site and logged-in product do not feel like two companies.

Auth, roles and permissions

Auth, roles and permissions

We build the boring gates properly: sessions, roles, protected routes, account states, invitation flows and server-side checks. The app should know who is allowed to do what before the button even renders.

Mutations that hold up

Mutations that hold up

Multi-step onboarding, settings screens, uploads, checkout handoffs, CRM syncs and admin actions need validation, optimistic states, retries and clear failure paths. That is where apps feel either polished or held together with tape.

Production operations

Production operations

Vercel Firewall rules, cache behavior, secrets, preview deployments, analytics events, error reporting, web vitals, redirects and rollback plans. The app is not finished when it compiles.

Where Next.js wins

Business cases we like

Next.js is a strong fit when the product has to mix public demand generation with private application logic. The same build can serve SEO pages, onboarding, account areas, customer data, AI chat, file workflows, admin tools and CMS-driven content without splitting the experience across separate frontends. Those public pages also have to hold up when an assistant reads them rather than a person, which is a different set of constraints from classic SEO.

For AI products, we pair the interface work with the orchestration work. AI Elements (opens in new tab) gives us a strong starting point for chat, tools, sources, reasoning states, attachments and workflow interfaces. Workflow SDK (opens in new tab) is where the longer-running parts belong: agent runs, human approval steps, retries, resumable streams, file processing, follow-ups and background jobs that need state and observability.

For portals, the shape is different but the standard is the same. Authentication, roles, permissions, dashboards, documents, payments, notifications and support workflows should sit in a clear product architecture. Best practice here means server-first data fetching, small client islands, typed validation, predictable mutations, careful cache boundaries and no hidden mess between the public site and the logged-in app.

The Vercel layer matters too. We tune runtime choices, caching, observability, firewall rules, deployment previews and AI Gateway usage so the app is fast, resilient and cost-aware. AI spend and Vercel spend are part of the architecture conversation from day one. Our community session on optimizing usage on Vercel shows the diagnosis and fixes we reach for.



Hire Next.js developers

How teams work with us

Most teams come to us when they need senior Next.js developers who can own the whole app, not a single slice of the frontend. We work as an embedded team: a lead engineer who learns your codebase, designers and developers alongside, and Vercel partner experience to draw on when the platform questions get hard.

You can hire us for a fixed-scope first version, an ongoing build, or a focused piece of work like an AI feature, an auth rebuild or a performance pass, such as the build pipeline we reworked for Trippin World's 5,000-page travel site, which took deploys from 30 minutes to 3. Either way you get developers who have shipped production Next.js across App Router, Server Components, streaming and edge routing, and who keep caching, observability, cost controls and the second release in view from day one. For a recent example, our Next.js 16.4 upgrade notes show what a version bump takes on a production monorepo.



Burning questions

Thinking about your next Next.js build?

The questions that come up on every Next.js scoping call.

What does a Next.js development agency actually do?

Build the application end to end: interface, app architecture, data and content layer, auth and permissions, and the Vercel deployment model. Those decisions interlock, which is the whole argument for one team owning them together.

Where it goes wrong is an agency that takes the React layer only and leaves caching, session handling, cost control and observability for someone else to solve later.

How much does it cost to hire a Next.js development agency?

Roboto Studio projects start at $25k. That matches our DesignRush minimum budget of $25,000 to $50,000 and our listed average of $200 an hour.

Above $25k the price depends on how much of the product already exists, whether auth and billing are in scope, how many systems sit behind the interface, and whether you want us shipping after launch. You get a scope and a price for the first version before anyone writes code.

What is the best Next.js development agency?

We are biased, so check the evidence. We are a Vercel Silver Solution Partner, so Vercel has reviewed our production work. Named US Next.js builds include Tray.ai (builds cut from a full day to 2 minutes, 500,000 pages migrated in six weeks), Slingshot Bio (WordPress and Shopify converged in three months) and Topaz Labs (documentation platform in four weeks).

Ask any agency you compare for named production URLs, who owns the App Router and caching decisions, and what happens to the Vercel bill after launch.

Can we hire Next.js developers to work inside our team?

Yes, and that is how most of our engagements run. A lead engineer learns your codebase and works in your repo and your standups, with designers and other developers alongside as the work demands.

You can also hire us for a fixed-scope first version, or for one focused piece of work like an auth rebuild, an AI feature or a performance pass.

Are you a Vercel partner?

Yes. Roboto Studio is a Vercel Silver Solution Partner.

Day to day that shows up in unglamorous places: runtime choices, cache boundaries, firewall rules, preview deployments, AI Gateway usage and keeping the bill predictable as traffic grows. We also have a direct line to Vercel's team when a platform question gets hard.

When is Next.js the wrong choice?

When the site is pure content with no application logic behind it. A brochure site or a documentation set is often better served by Astro, and we will tell you that rather than sell you a heavier build.

Next.js earns its complexity when marketing pages and a logged-in product have to live in one codebase: SEO pages, onboarding, account areas, dashboards, admin tools and AI features on the same deploy.

How long does a Next.js project take?

For a first version of a focused app, weeks rather than quarters. Topaz Labs' documentation platform took four weeks. Slingshot Bio's headless commerce build took three months from design to launch. Tray.ai's re-platform migrated 500,000 pages in six weeks.

Portals and AI products with real auth, billing and third-party integrations take longer, and we scope those in stages.

Will you work on an existing Next.js codebase?

Often. Inherited apps are a steady part of the work: Pages Router upgrades, App Router migrations, rendering and caching that got away from the team, Vercel bills nobody can explain.

We start with an audit and tell you honestly whether the codebase is worth extending or whether the parts causing the pain need rebuilding.

Do you have a US office?

Yes. Roboto Studio's office is at 2021 Fillmore St, San Francisco, CA 94115. Bay Area Next.js work includes Tray.ai in San Francisco and Slingshot Bio in Emeryville.
