What Custom Software Actually Delivers — And What Off-the-Shelf Never Will

Your team opens a SaaS dashboard and immediately starts building workarounds — spreadsheets, Zapier chains, manual data exports — because the tool covers 60% of your workflow and breaks the rest. Custom software development means we write the exact application your business needs, not a feature checklist built for someone else's use case. We build on Next.js 14 with App Router, Supabase for Postgres and row-level security, and Vercel's edge network. That stack gives your team server-side rendering, real-time WebSocket subscriptions, instant rollbacks, and sub-200ms TTFB without managing a single EC2 instance. You get a dedicated senior engineer — not a rotating bench of juniors — who scopes a fixed-price contract before touching your repo. The output is a production application with CI/CD on GitHub Actions, Playwright E2E tests, and documentation your engineers can actually maintain. You own everything: the codebase, the Supabase project, the Vercel account. No license fees, no vendor lock-in, no surprise invoices when your usage spikes.

專案失敗的原因

Your offshore team shipped code that scores 40 on Lighthouse and crashes under real traffic. Every month of poor performance costs you 7% conversion rate per second of load time.
You're paying $3K/month for a SaaS tool that covers 60% of your workflow and breaks the rest. Your team builds workarounds that become tech debt — compounding costs quarter over quarter.
Your current vendor disappeared mid-project and left undocumented spaghetti code. Rewriting from scratch costs 2-3x what finishing correctly would have cost.
You need real-time features but your monolith can't support WebSocket connections at scale. Competitors with live data views are closing deals you're losing to stale dashboards.
Your internal tool runs on a five-year-old React app with no tests and no deploy pipeline. One bad merge takes down the tool your entire engineering org depends on daily.
Security review flagged your app for missing row-level access control and unencrypted PII. A single data breach costs mid-market companies an average of $3.86M according to IBM's 2024 report.

我們構建的內容

Stop paying $3K/month for SaaS tools that force your team into daily workarounds

Ship server components, parallel routes, and streaming SSR — fast loads without client-side rendering bloat

Fire the offshore vendor who shipped a 40-Lighthouse app that crashes under real traffic

Deploy OAuth, magic links, and Postgres with row-level security policies enforced at the database layer

Replace the five-year-old internal tool with no tests and no deploy pipeline

Get preview deployments on every PR, instant rollbacks, and edge functions in 30+ regions

Fix the monolith that can't support WebSocket connections for real-time features

Add live dashboards, notifications, and collaborative features with Supabase Realtime over WebSockets

Eliminate undocumented spaghetti code left behind by a disappeared contractor

Run Playwright E2E tests, TypeScript strict checks, and Lighthouse CI on every push — broken builds never ship

Pass security review after flagged missing row-level policies and unencrypted PII

Own your repo, Supabase project, and Vercel account with full migration docs and deployment steps

我們的流程

常見問題

自訂軟體開發的實際成本是多少?

我們的大多數專案落在 $25K 至 $200K 之間。具有身份驗證、幾個核心檢視和 Supabase 後端的專注內部工具或 MVP 通常運行 $25K-$60K。具有即時功能、第三方整合和管理儀表板的多角色平台位於 $80K-$150K 範圍內。具有合規性要求、SSO 和複雜資料管道的企業構建可能超過 $150K。我們在付費發現週後確定固定價格合約的範圍,因此您在開始構建前就會知道確切的數字。

為什麼選擇 Next.js + Supabase 而不是傳統後端?

Next.js 在一個框架中提供伺服器端渲染、API 路由和 React — 無需單獨的前端和後端存儲庫。Supabase 用託管 Postgres、內置身份驗證、即時訂閱和行級安全性替代自訂後端。Vercel 將所有內容部署到邊緣,零 DevOps。結果:更少的活動部件、更快的迭代和更低的託管成本。典型的 Supabase Pro 計畫每月運行 $25,相比之下等效的 AWS 基礎架構每月 $200-$500。您並未放棄控制權 — 您擁有 Postgres 資料庫,可以將其遷移到任何地方。

典型專案從開始到啟動需要多長時間?

四到十二週,取決於範圍。具有三到五個核心功能的專注 MVP 在四到六週內交付。具有即時資料、基於角色的存取和第三方整合的完整平台需要八到十二週。我們不會填充時間表 — 我們的流程步驟是固定的,我們每週交付預覽部署,因此您永遠不會猜測進展情況。

專案團隊是什麼樣的?

您將與擁有程式碼庫的資深工程師和管理範圍和溝通的專案主管合作。對於較大的構建,我們添加第二名工程師或專業 QA 專家。我們不使用初級開發人員並收取資深費率。您的 Slack 頻道直接連接到編寫程式碼的人員 — 沒有帳戶經理轉達訊息。

啟動後我們擁有程式碼和基礎架構嗎?

是的,完全擁有。GitHub 存儲庫位於您的組織中。Supabase 專案在您的帳戶上。Vercel 部署在您的團隊下。我們在交付期間轉移所有內容,包括環境變數、遷移文件和操作手冊。沒有授權費、沒有專有框架、沒有合約限制。如果您想將維護帶回內部或稍後僱用另一家機構,您可以 — 程式碼庫是標準的 Next.js 和 TypeScript。

如果專案範圍在構建中期改變會怎樣?

範圍變化會發生。我們通過變更單來處理它們 — 一份文件,描述新工作、成本差異和時間表影響。我們在編寫任何程式碼前需要您批准。大多數專案會看到一到兩個小的變更單。我們構建架構以適應增長,因此在啟動後添加新功能不意味著重寫基礎。

您提供哪些效能保證?

我們在啟動時保證在行動設備上 90+ 的 Lighthouse 效能評分。這被寫入合約。如果我們沒有達到,我們在 30 天保固期內免費修復它。我們還在 Vercel 的邊緣網絡上以低於 200ms 的首字節時間為目標,並使用 k6 運行負載測試以驗證應用程式在上線前能處理您預期的流量。

您如何處理安全性和資料合規性?

Supabase 行級安全策略在資料庫層級強制執行存取控制 — 不僅僅在 UI 中。我們配置處處使用 HTTPS、設定正確的 CORS 標題、清理輸入,並在啟動前根據 OWASP Top 10 進行審查。對於需要 SOC 2 或 HIPAA 對齐的團隊,我們確定額外控制的範圍,如審計日誌、靜態加密和存取審查。Supabase 在 AWS 上運行,具有 SOC 2 Type II 認證,為您提供強大的基礎架構基礎。
