When three Next.js apps repeat the same setup or shared-component work, the answer may be a common foundation—not one giant application, and not a collection of one-off fixes. A framework can mean shared packages, conventions, and tooling that help the apps stay consistent while remaining separately deployable. Whether that would have solved the problems behind the original “duct-taping” decision depends on the project’s actual pain points; the title alone does not establish them.
What does “build a framework” mean here?
It need not mean replacing Next.js or creating a new runtime. In this context, the practical interpretation is a shared foundation for multiple Next.js applications: reusable packages for common code, plus conventions and tooling that reduce the need to configure each app from scratch. The apps can still have their own routes, code, and deployment boundaries.

That distinction matters. Sharing a repository or library does not automatically turn several apps into one deployable application. Turborepo’s guide shows how to add Next.js apps to a monorepo, while Next.js documents sharing code through either a monorepo or public or private npm packages. Turborepo’s Next.js monorepo guide and Next.js Multi-Zones guidance describe distinct ways to organize apps and shared code.

Start with the friction, not the architecture label
“Duct-taping” can describe very different problems: duplicated components, repeated configuration, cross-app routing, or teams that need independent releases. Those problems point to different solutions. A public Next.js discussion poses one concrete version of the question—how to share components across three or more apps in separate repositories—but it is an example of the concern, not evidence that every multi-app team has the same needs. The discussion asks specifically about shared components across repos.
#1 Best Overall
- If the repeated work is source code or setup, shared packages and coordinated tooling may address it.
- If the key need is independent ownership or release, retain separate applications and consider how they will be composed and routed.
- If users frequently move between sections, assess the navigation consequences of splitting those sections across apps.
- If teams need runtime composition, account for shared-library compatibility as well as the flexibility it provides.
Before choosing, list the repeated work and identify who owns each app, how users move between them, and which dependencies must stay compatible. Without those project-specific facts, a claim that a framework improved outcomes—or that it was the right choice for the author—would be speculation.
Compare the main ways to organize the apps
| Approach | How apps share or connect | What it can help with | Costs and constraints to assess |
|---|---|---|---|
| Shared repository with separate apps and packages | Apps and reusable packages live in one repository; shared source is available at build time. | Common code and coordinated tooling while retaining app boundaries. Turborepo describes using workspaces to group packages, with apps for deployables and packages for reusable libraries. Turborepo guide. | Colocation does not prove that every app belongs in one repository or that builds will be faster. Decide which packages are genuinely reusable and how changes affect each app. |
| Next.js Multi-Zones | Separate applications serve different URL paths. Code can be shared through npm packages; a monorepo can make sharing more convenient. Next.js Multi-Zones guide. | Separate deployment boundaries when applications need more independence. Zones may use different frameworks. Next.js guide to Multi-Zones. | Moving between zones can cause hard navigations. Keep pages often visited together in one zone when possible; links across zones should use standard anchor elements rather than Next.js Link. |
| Runtime Module Federation | A host and remote applications are composed at runtime. | Runtime flexibility for a micro-frontend arrangement. Nx describes Module Federation as a common micro-frontend approach. Nx Module Federation guide. | Shared dependencies need coordination: Nx warns that federation can break when apps load incompatible copies of shared libraries, such as different React versions. |
Why a shared foundation can beat one-off glue
When duplication is the actual problem, a common foundation gives teams a place to maintain reusable code and shared conventions without requiring every application to become a single application. That is a structural advantage, not a guaranteed productivity or build-time improvement. The right test is whether the shared pieces correspond to recurring needs and remain useful across the apps.
Rank #2
Keep the boundary explicit: shared packages should contain code that multiple apps truly use, while app-specific routes and behavior stay with the app that owns them. A shared repository can make those packages easier to develop alongside their consumers, but it also means teams should understand which apps a shared change could affect.
When keeping the apps more separate makes sense
Separate apps can be appropriate when teams need stronger ownership or deployment independence. Multi-Zones provides one way to route distinct URL paths to separate applications, but the path boundary affects navigation: Next.js recommends keeping pages commonly visited together in the same zone to avoid hard navigations. For links that cross zones, use ordinary anchors rather than the Next.js Link component. Next.js Multi-Zones documentation.
Runtime federation is another form of separation, but it shifts some coordination to runtime: shared libraries need compatible versions. Neither approach is automatically better than a shared repository; the choice depends on how much isolation is needed and how much navigation and dependency coordination the project can accept.

A shared application framework describes how code and conventions are organized; it does not dictate a particular hosting provider. Next.js states that the minimum runtime requirement is a Node.js server. Its deployment guide also explains that additional infrastructure—such as CDN caching, edge compute, or shared cache—primarily supports performance or consistency across multiple instances, rather than being a prerequisite for the framework itself. Next.js: Deploying to Platforms, updated March 25, 2026.
For the documented single-process deployment model, Next.js says: “A single next start process handles every Next.js feature correctly: Server Components, ISR, PPR, Cache Components, Server Actions, Proxy, and after().” That statement describes the documented model; it does not mean every production deployment needs no additional infrastructure.

A practical decision sequence
- Name the repeated cost. Separate duplicated components or configuration from routing friction, release coordination, and team-ownership concerns.
- Choose the sharing boundary. If the apps need shared source and tooling, evaluate a workspace monorepo with separate apps and reusable packages. If they need stronger isolation, evaluate separate apps connected through path routing or runtime composition.
- Check the user journey. Map which pages users commonly visit in sequence. If those pages land in different Multi-Zones, account for hard navigation and use standard anchors between zones.
- Check dependency ownership. For runtime federation, establish how shared libraries such as React remain compatible. For shared packages, decide how changes are tested against their app consumers.
- Keep deployment decisions separate. Choose hosting and infrastructure based on runtime, performance, caching, and operational needs—not merely because a shared framework exists.
- Evaluate the result against the original friction. Track whether the repeated setup or coordination work actually declines; do not assume that a monorepo, framework, or federation layer produces that result by itself.
