What a Next.js Agency Actually Builds — And What National Shops Won't

Your deploy ships to Vercel with App Router, Server Components, and Supabase already wired. We build production React apps for LA's SaaS platforms and DTC brands — the kind that handle real traffic without falling over. Your team gets TypeScript end-to-end, streaming SSR that hits sub-200ms paint, and row-level security policies written into your schema from commit one. Not WordPress with a React veneer. Not a six-month discovery phase that burns your runway while competitors ship. Just working Next.js code that scales with your business and meets California's compliance requirements before your legal team ever asks.

Où les projets échouent

Your product pages are probably shipping 2MB of JavaScript right now Every extra second of load time drives bounce rates up 32%, and those are LA customers you're losing.
Your dev team is still writing Pages Router patterns from 2022 Parallel routes, streaming, partial prerendering — competitors are already running these. You're not.
You're paying Firebase prices that grow with every user Switch to Supabase's PostgreSQL backend and you're typically looking at 60% lower auth and database costs at the same scale.
When your CMS is coupled to your frontend, every redesign turns into an engineering project Decouple it and your content team ships independently — no tickets, no waiting.
National agencies want $150K and six months to build a SaaS dashboard you needed last quarter Your runway disappears while they run discovery phases that somehow never end.
California-based SaaS companies need CCPA compliance baked into the stack from day one One intentional violation runs $7,500 under California law. That adds up fast.

Conformité

React Server Components

Server Components render on the server and send zero JavaScript to the browser for static content. On product pages and SaaS dashboards, that typically cuts bundle sizes by 50–70%.

App Router Architecture

Nested layouts, parallel routes, intercepting routes — it's all in the file system. Navigation patterns that used to take weeks now take days to build.

Supabase Backend

PostgreSQL database, row-level security, edge functions, realtime subscriptions. Supabase is an open-source Firebase alternative that doesn't hold your data hostage or charge you into oblivion as you grow.

Vercel Edge Deployment

Every pull request gets a preview URL. LA-based edge nodes keep response times under 100ms for your SaaS and DTC customers without any extra configuration.

Headless CMS Integration

Sanity, Prismic, or Contentful wired into your Next.js build with type-safe schemas. Your content team publishes without touching code or waiting on a deploy window.

Core Web Vitals Tuning

We configure image optimization, font loading, and streaming SSR per-route. We're targeting 95+ Lighthouse scores because Google ranks on performance, not on what your agency promised.

Ce que nous construisons

Stream content progressively so buyers see product grids in under 200ms

Your buyers stay engaged because skeleton states load instantly while data streams in

Build multi-tenant auth with database-level security policies, not middleware hacks

Your SaaS handles role-based permissions and tenant isolation without security patches

Catch type errors at build time across your entire stack before users do

Your CI pipeline rejects breaking changes before they hit staging or production

Ship analytics and error tracking without bolting on third-party scripts later

Your product team sees real Web Vitals and conversion funnels the day your app goes live

Rebuild product pages on demand without redeploying your entire DTC catalog

Your content team publishes new SKUs without waiting on engineering or redeploy windows

Embed CCPA data deletion and consent hooks into your Supabase schema upfront

Your legal risk drops because audit trails and consent management are already in your database

Notre processus

01

Stack & Scope Audit

We look at your current architecture, find the bottlenecks, and spec out the full Next.js stack — App Router patterns, Supabase schema, CMS models, Vercel config. You get a fixed-fee proposal. Not a retainer pitch.
Week 1
02

Foundation Build

First we stand up the foundation: App Router layouts, Supabase connection, headless CMS integration, auth flows, CI/CD on Vercel. Preview deploys are live from day one.
Weeks 2-3
03

Feature Development

Then we build. Server Components handle the data-heavy pages, client components handle interactivity, API routes manage third-party integrations. Every feature ships behind preview URLs so stakeholders can actually review it.
Weeks 4-7
04

Performance & QA

Before launch: Core Web Vitals, accessibility audit, cross-browser testing, load testing against realistic traffic. We fix problems before users find them.
Week 8
05

Launch & Handoff

Production deployment on Vercel, monitoring configured, documentation written, 30 days of post-launch support included. Your team inherits a codebase they can maintain without calling us every week.

Questions fréquentes

Pourquoi embaucher une agence Next.js à Los Angeles plutôt qu'une équipe distante ?

Être à LA a vraiment un impact ici. Revues de sprint en personne, communication en heure du Pacifique, aucun décalage horaire quand vous coordonnez avec les équipes de design et marketing. On connaît aussi le marché californien — Silicon Beach, CCPA, tout ça.

Combien coûte un projet Next.js à Los Angeles en 2026 ?

Les projets LA Next.js coûtent entre 8 K$ pour les sites marketing et 60 K$+ pour les plates-formes SaaS complètes avec Supabase, auth et tableaux de bord. Les builds enterprise avec des fonctionnalités IA commencent autour de 75 K$. Tout est à prix fixe après un audit de périmètre — vous connaissez le total avant de signer. Pas de surprises de facturation horaire.

Quel est l'avantage d'App Router par rapport à Pages Router ?

App Router dispose de layouts imbriquées, de routes parallèles, de routes interceptantes et de React Server Components intégrés. La navigation SaaS complexe s'affiche plus rapidement avec moins de JavaScript. Pages Router fonctionne toujours bien, mais App Router est la valeur par défaut dans Next.js 15 et c'est vers là que le framework va — les nouveaux projets devraient commencer là.

Pourquoi utiliser Supabase au lieu de Firebase pour un backend SaaS ?

Supabase fonctionne sur PostgreSQL. Vous obtenez la sécurité au niveau des lignes, l'accès SQL complet et aucun verrouillage de fournisseur. La base de données NoSQL propriétaire de Firebase devient chère à grande échelle et a du mal avec les requêtes complexes. Supabase inclut les edge functions, le temps réel et l'auth — tout open-source. Si vous dépassez le service managé, vous pouvez l'auto-héberger.

Comment les Server Components améliorent-elles les performances des sites DTC ?

Les Server Components envoient du HTML. Aucun bundle JavaScript pour ces composants ne franchit jamais le navigateur. Une page de liste de produits qui avait l'habitude de livrer 400 KB de code React envoie maintenant 50 KB. Le contenu se charge plus rapidement, Google l'indexe immédiatement, et les scores Lighthouse augmentent de 20–30 points sans changer l'apparence.

Gérez-vous la conformité CCPA pour les apps basées en Californie ?

Oui. Les endpoints de suppression de données, l'interface de gestion du consentement et la journalisation d'audit sont intégrés au schéma Supabase dès le départ. CCPA exige que les utilisateurs puissent demander l'exportation et la suppression de données — nous intégrons ces routes API dans l'application principale, pas après coup six mois avant un audit.
