Next.js Development in the US
We are an Indian engineering team working with businesses in the US. Written scope before any code, and a fixed quote in USD.
Working hours
Our day ends at 07:30 in the US (08:30 on summer time), before yours begins, so we work asynchronously: written updates land overnight and are waiting when you start.
Quoted in USD
There is no general VAT in the US at present, so the quote is the amount you pay.
Data protection
Work for this market is scoped against state privacy law, principally the CCPA and CPRA in California, agreed before development starts rather than retrofitted afterwards.
Written scope
Every engagement starts with a written scope and a fixed USD quote within 24 hours, so the price is set before work begins.
About Next.js Development
Next.js is our default for any modern web project where SEO, performance, and developer experience all matter. We've shipped 8+ production Next.js apps on the App Router across SaaS dashboards, headless e-commerce, content sites, and marketing pages, including this one. Every build uses TypeScript, Tailwind, and the latest Next.js patterns, deployed to Vercel for the fastest possible iteration loop.
What the engagement includes
- Next.js 16 (App Router) custom application development
- Headless Shopify storefronts on Next.js
- Headless WordPress front-ends on Next.js
- Multi-region SaaS dashboards with auth (Clerk, Auth.js)
- Server Actions, Suspense boundaries, and streaming SSR
- Static export sites for content / marketing
- TypeScript-first codebases with strict mode
- Migration from Pages Router → App Router
What CISA's exploited-flaw catalog, Section 1557 and FIPS 140-3 ask of a US Next.js build
In the US the deadline for patching a framework flaw can be set by a federal agency, and Next.js has already been on that list. On 3 December 2025 React disclosed a remote code execution flaw in React Server Components, CVE-2025-55182, rated CVSS 10.0, and Next.js published its own advisory the same day for App Router applications on 15.x, 16.x and late 14.3 canaries, with no workaround short of upgrading. Pages Router applications and the Edge runtime were not affected. CISA added the React flaw to its Known Exploited Vulnerabilities catalog on 5 December 2025 with a due date of 12 December, one week later, and the catalog now records its use in ransomware campaigns as known. Under Binding Operational Directive 22-01, federal civilian agencies must remediate catalog entries by the due date, and because the catalog is public, any American security reviewer can hold your release history up against it and ask how long a listed flaw stayed open in your product. On 6 December Next.js added that any application online and unpatched as of 4 December at 1:00 p.m. Pacific should rotate its secrets, which is the part a version bump does not cover: database credentials, API keys and session signing keys sit in the environment of exactly the server process that was exposed. So a Next.js build we hand over carries three safeguards for a week like that. Renovate or Dependabot watches next, react and react-dom, with a written policy that an advisory on the catalog is merged and deployed within days rather than at the next sprint. Every secret the server reads lives in a secrets manager and can be rotated by script without a code change. And deployment is reproducible from the lockfile, so patching a production line on 15.3 means moving to 15.3.6, not an unplanned jump to a new major in the middle of an incident. Whether your contracts impose a patch window is for your own counsel and security team.
If the site belongs to a health program that takes federal money, the language switcher is a regulated component. HHS's Section 1557 rule, effective since 5 July 2024, applies to health programs and activities that receive federal financial assistance from the Department. Since 5 July 2025 a covered entity has had to post a notice that free language assistance services and auxiliary aids are available, at a conspicuous location on its website, in English and in at least the 15 languages most commonly spoken by people with limited English proficiency in the state or states where it operates. The same notice has to travel with a list of electronic communications that a patient portal or member site generates: application and intake forms, notices of denial, communications that ask for a response, billing and collections material, consent forms, discharge papers and complaint forms. Where machine translation is used for text critical to a person's rights or benefits, where accuracy is essential, or where the language is technical, a qualified human translator must review it. In a Next.js App Router project that has concrete consequences. The App Router has no built-in i18n configuration, so the locale lives in a route segment with dictionaries loaded on the server, and because the 15 languages are counted per state, a group operating in several states needs the tagline set chosen by state rather than one national list. Where a state's list includes a right-to-left script such as Arabic, the dir attribute is set from the root layout per locale rather than patched in CSS. Generated documents such as statements and discharge papers render from templates that carry the tagline block, and the translation pipeline records which strings were machine translated and who reviewed them, because that record is the evidence the rule asks for. Whether you are a covered entity, and for which states, is for your own counsel.
Federal work brings a cryptography requirement that a default Next.js stack does not meet. Federal systems are expected to protect data with cryptographic modules validated under FIPS 140, and NIST's validation program has just closed a chapter: FIPS 140-2 validations stayed active until 21 September 2026, and every FIPS 140-2 certificate moved to the Historical List on 22 September 2026. NIST says modules on that list can still be bought and used for existing systems, but agencies decide when they require FIPS 140-3 modules only, so a system proposed now should be built around 140-3. The Node.js documentation is plain that Node.js itself is not validated. It exposes whatever the linked OpenSSL provides, and with OpenSSL 3 that means an installed FIPS provider, loaded through a configuration file at startup, with the fips=yes property set through that file, --enable-fips or --force-fips. Next.js adds a runtime question. Code on the Edge runtime runs inside the hosting platform's isolates, where you cannot load a validated module of your own, while Next.js 16, released on 21 October 2025, replaced middleware.ts with proxy.ts and runs it on the Node.js runtime, leaving the old middleware file deprecated for edge use. So for a US federal or defense buyer we keep request interception in proxy.ts and route handlers and server actions on Node, start the server with the FIPS provider active from a base image whose module certificate we can name, and choose primitives the module approves: PBKDF2 for stored passwords rather than bcrypt or Argon2, which are not FIPS-approved algorithms, and AES-GCM for anything encrypted at the application layer. TLS terminating at a load balancer needs the same scrutiny, since a validated application process behind an unvalidated endpoint does not settle the question. Which systems inside your boundary must use validated modules is for your security officer and contracting officer.
How we work with US clients
A US engagement gets agreed twice. Once with the person who wants the thing built, and then again with legal, security, procurement and finance, who arrive separately and rarely in the same week. That second round is where a supplier outside the country loses the calendar: a master services agreement to redline, a security questionnaire, a certificate of insurance, and a vendor portal that assumes everyone it onboards can sign a W-9. Send all of it while the scope is still being written rather than in the week you wanted to start, and where the honest answer to a row is that we do not hold something, we write that in rather than leaving it blank.
You are also buying from a company you cannot drop in on, so the evidence has to do the work an office would otherwise do. What we send is live production URLs rather than a deck, a written scope with one fixed number against it, and the names of the people who will do the work rather than a bench that changes after signature. What we will also tell you is the shape of what you are hiring: a small team in Noida that has been building since 2021, not a firm that can put four more people on your project next Monday. If that is what your timeline needs, we say so before the contract rather than after it.

Does our site have to meet ADA accessibility requirements?
If you are consumer facing in the US, build as though it does. Demand letters over inaccessible websites are routine and cheap to send, federal work brings Section 508 with it, and the Department of Justice rule under Title II sets WCAG 2.1 AA for state and local government entities on a timetable your counsel can confirm for your size band. We work to WCAG 2.2 AA and test with a screen reader rather than relying on an automated scan, because automated tools catch perhaps a third of real issues and the other two thirds are the ones that end up in a letter.
How do we know you will still be here in two years?
Nobody can promise you that, and a supplier who does is selling something. We have been building since 2021 and we maintain what we build, which is the honest version of the answer. The useful version is that it should not have to matter. The repository is in your GitHub organization, the domain and hosting accounts are in your company name, the stack is Next.js, Laravel, Flutter and Postgres rather than anything only we can read, and the handover document exists before you ask for it. If we vanished tomorrow, another agency could pick it up without needing to call us.
Can you sign our NDA and work under our MSA?
Yes to the NDA. Send your standard one and it comes back signed within 24 hours, before you describe the project in any detail. Yes to the MSA too, with the caveat that we read it properly rather than signing to be agreeable. The two clauses we usually come back on are unlimited liability, where we ask for a cap tied to the fees, and an IP clause drafted broadly enough to sweep in the internal tooling we bring to every project. Everything built for you transfers to you in full on final payment. We mark up those two and sign the rest.
Something breaks at two in the afternoon in Chicago. What actually happens?
Two in the afternoon in Chicago is past midnight here, half past midnight in summer and half past one in winter, so the truthful answer depends on what you are paying for. Monitoring does not keep our hours and the alert fires whatever the clock says. Whether a person is awake to act on it depends on your plan, because we are not a 24/7 on-call operation as standard, and we would rather tell you that while you are choosing a plan than while your checkout is down. Without out-of-hours cover written into the contract, the realistic answer is that it is picked up at the start of our day, which is the middle of your night, and you should price that in when you decide.
Next.js Development: common questions
How much does a Next.js project cost?
Marketing sites: $460-$1,100. SaaS dashboards / web apps: $1,100-$3,400. Headless e-commerce or enterprise builds: $2,900+. Final cost depends on number of authenticated surfaces, integration count, design fidelity, and whether content is from a CMS or hardcoded.
Should I build on Pages Router or App Router?
App Router for any new project starting in 2025+. Pages Router is now legacy, Vercel is investing entirely in the App Router, and the developer experience is meaningfully better once you accept the server-first mental model. We migrate Pages Router projects to App Router for clients regularly.
Do you deploy to Vercel or somewhere else?
Vercel by default for ~80% of clients, it's the frictionless path and integrates natively with Next.js features. Netlify for static-export sites where the cost model is better. AWS via OpenNext when compliance dictates AWS-only deployments. Self-hosted Node when there's a specific reason.
Can you build the backend for the Next.js app too?
Yes. We build full-stack solutions, Next.js front-end + Server Actions/API routes for the data layer, with Supabase, Drizzle ORM, or a separate Laravel/Node backend depending on the data model and team. We pick the right backend for the project, not a default we always use.
Will the Next.js site have good SEO?
Yes. Every Next.js build we ship includes proper metadata API usage, generated sitemap.xml and rss.xml, JSON-LD structured data per page type, dynamic OG images, and Core Web Vitals tuned to 95+. We also handle Search Console verification and submit the sitemap as part of launch.
