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.

プロジェクトが失敗する理由

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.

コンプライアンス

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.

構築する内容

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

私たちのプロセス

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.

よくある質問

なぜリモートではなくLos Angelesの Next.js エージェンシーを雇うのか?

LAにいることは実際に重要です。対面でのスプリントレビュー、太平洋時間でのコミュニケーション、デザインとマーケティングチームとの調整時のタイムゾーン摩擦がありません。カリフォルニア市場も理解しています — Silicon Beach、CCPA、全て。

2026年のLos Angelesでの Next.js プロジェクトの費用はいくら?

LA Next.js プロジェクトはマーケティングサイト向け $8K から Supabase、認証、ダッシュボードを含むフルSaaS プラットフォーム向け $60K+ まで実行されます。AI機能を備えたエンタープライズビルドは $75K からです。スコープ監査後はすべて固定料金です —署名する前に合計金額がわかります。時間単位の請求の驚きはありません。

App Router と Pages Router の利点は何か?

App Router にはネストされたレイアウト、並列ルート、インターセプトルート、React Server Components が組み込まれています。複雑な SaaS ナビゲーションは JavaScript が少ないほど高速にレンダリングされます。Pages Router はまだ正常に動作しますが、App Router は Next.js 15 のデフォルトであり、フレームワークが向かう先です — 新しいプロジェクトはそこから始まるべきです。

SaaS バックエンドに Firebase の代わりに Supabase を使用する理由は?

Supabase は PostgreSQL で実行されます。行レベルセキュリティ、完全な SQL アクセス、ベンダーロックインなしが得られます。Firebase の独自の NoSQL データベースはスケール時に高くなり、複雑なクエリで苦労します。Supabase にはエッジ関数、リアルタイム、認証が含まれます — すべてオープンソースです。マネージドサービスを超えた場合、自分でホストできます。

Server Components はDTCサイトのパフォーマンスをどのように改善するか?

Server Components は HTML を送信します。これらのコンポーネント用の JavaScript バンドルはブラウザに到達しません。かつて 400KB の React コードを出荷していた製品リストページは、現在 50KB を出荷しています。コンテンツはより高速に読み込まれ、Google は即座にインデックスを作成し、Lighthouse スコアは視覚的に何も変更することなく 20~30 ポイント跳ね上がります。

カリフォルニアベースのアプリの CCPA コンプライアンスを処理しますか?

はい。データ削除エンドポイント、同意管理 UI、監査ログは最初から Supabase スキーマに組み込まれます。CCPA はユーザーがデータエクスポートと削除をリクエストできることを要求します — これらの API ルートはコアアプリケーションに組み込まれており、監査の 6 か月前の事後的な考慮ではありません。
