Next.js SaaS → native iOS and Android.
Brownfield is Rewrite's home turf
Rewrite scans real repos — monorepos, Next.js App Router, API routes, env patterns — and maps what matters for native scope. Your backend stays put; the app talks to the same APIs with native HTTP clients and platform auth flows.
Integrations that must not be stubbed
Stripe, Firebase Auth, Auth0, Supabase, OAuth, WebSockets, push, file upload, analytics, search — if the scan finds them, native delivery should emit working counterparts. URLSession alone is the floor, not the ceiling. See our open-source integration registry for depth.
Scope honestly: not every admin page needs day-one mobile
Pick the flows customers need on a phone first — login, core actions, settings. Rewrite quotes conservative bands for agreed scope so you're not paying for undefined 'everything.' Expand later with clear deltas.
Compile proof before the big check
Hosted Simulator and emulator screenshots show the actual SwiftUI and Compose you're buying. Fidelity scoring compares native output to approved references — not browser HTML pretending to be an app.
Common questions
Do we need to rewrite our backend?
No. Native apps call your existing APIs. Rewrite focuses on client-native implementation for in-scope surfaces.
Monorepo with apps/web?
Supported — point scan at the right package. Route discovery and live sitemap capture help when the repo layout is nested.
What about internal admin dashboards?
Often out of scope for v1 mobile. Align in the guided flow; ship customer-facing flows first.
