Streamlined Next.js 15 Migration

The transition to Next.js 15 introduces several breaking changes, most notably the shift to **Asynchronous Request Context**. The **DevUtility Hub Migration Auditor** identifies these patterns in your code and provides the correct 2026-standard refactors.

🔍 What we Audit

- **Async Headers & Cookies:** Surface non-awaited calls to headers() and cookies() in layouts and pages.

- **Param Destructuring:** Fix sync destructuring of params and searchParams in Route Handlers.

- **React 19 Compatibility:** Identify legacy context providers that should be migrated to the native use() hook.

- **Caching Logic:** Check for deprecated unstable_cache patterns.

Stay Ahead of the Build

Don't wait for your CI/CD pipeline to fail. Audit your code locally and ensure your application is ready for the concurrent rendering future of React 19 and Next.js 15.

Zero-Knowledge Execution & Edge Architecture

Unlike traditional monolithic developer utilities, DevUtility Hub operates entirely on a Zero-Knowledge architectural framework. When utilizing the Next.js 15 Migration & Tech Auditor, all computational workload is completely shifted to your local execution environment via WebAssembly (Wasm) and your browser's native JavaScript engine (such as V8 or SpiderMonkey).

Why Local Workloads Matter

Transmitting proprietary JSON objects, sensitive source code, or unencrypted text strings to an unknown third-party server introduces critical security vulnerabilities. By executing the Next.js 15 Migration & Tech Auditor securely within the isolated sandbox of your Document Object Model (DOM), we structurally guarantee strict compliance with major data protection regulations like GDPR, CCPA, and HIPAA. We do not ingest, log, or telemetry your text payloads. Your local RAM serves as the absolute boundary.

Network-Free Performance

Furthermore, by completely eliminating asynchronous HTTP POST payloads to a centralized cloud infrastructure, we guarantee effectively zero latency. The Next.js 15 Migration & Tech Auditor provides instant execution without arbitrary rate limits, artificial file size constraints, or server timeouts. Our global edge network serves the application wrapper, while your local machine handles the heavy lifting.
