Frontend cloud for React & Next.js
We build and ship high-performance web applications on Vercel with Next.js, Turborepo, and edge-first architecture. From ISR to RSC, we help product teams deliver faster experiences with fewer infrastructure headaches.
Vercel is the deployment platform purpose-built for frontend frameworks — Next.js, Remix, Astro, SvelteKit. But reducing it to hosting misses the point entirely. Vercel provides a complete frontend infrastructure layer: Edge Middleware intercepts requests at CDN nodes before they reach your origin, ISR serves stale content while regenerating in the background, Image Optimization handles format detection and responsive sizing at the edge, Analytics tracks real-user Core Web Vitals across every deployment, and Conformance enforces framework best practices as build-time rules. The platform eliminates the operational overhead that frontend teams should never have to think about — cache invalidation, global distribution, and build optimization are handled by the infrastructure, not your engineers.
CloudForge builds production-grade Vercel architectures for organizations that need enterprise-level controls beyond what a solo developer configures. That means SSO with SAML and SCIM provisioning, audit logs piped to your SIEM, spend budgets with alerting thresholds per team, and preview environments that scale across hundreds of concurrent pull requests without blowing up your bill. We configure deployment protection rules that enforce approval workflows for production, environment variables governance that prevents secrets from leaking into preview deployments, and branch-based deployment policies that map your Git workflow to your infrastructure topology.
Our Vercel practice focuses on the patterns that break at scale: monorepo support with Turborepo where shared packages build incrementally and remote cache eliminates redundant computation across CI runs, Edge Config for feature flags that evaluate at CDN nodes without origin round-trips, multi-tenant architectures where each customer gets a custom domain with isolated configuration but shares the same codebase, and hybrid rendering strategies that assign static, SSR, ISR, or client-side rendering per route based on content freshness requirements and traffic patterns.
Server Components, streaming, and parallel routes for complex application architectures.
Incremental Static Regeneration with webhook-triggered revalidation for always-fresh content.
Request-level logic at the edge for A/B testing, geolocation, and authentication.
Automatic preview URLs for every PR with comments and visual regression checks.
Real-user monitoring with Core Web Vitals tracking and performance budgets.
Optimized builds with remote caching, task pipelines, and shared configuration.
Shared packages (UI library, config, types) consumed by multiple Next.js apps in a single repository. Turborepo handles task orchestration with dependency-aware caching — changed packages trigger rebuilds only in dependent apps. Remote cache on Vercel stores build artifacts across CI runs and developer machines, eliminating redundant compilation.
Organizations with 2+ frontend applications sharing design systems, configuration, or business logic that need coordinated deployments and consistent build performance across teams.
Pages are statically generated at build time with a revalidation interval. Stale content is served instantly while regeneration happens in the background. Webhook endpoints trigger on-demand revalidation when CMS content changes, ensuring pages update within seconds of editorial publishes without full rebuilds.
Content-heavy sites with thousands of pages where build times would be prohibitive, editorial teams that need near-instant publish visibility, and high-traffic pages where origin load must be minimized.
Middleware runs at CDN edge nodes before the request reaches the origin. It reads cookies to assign users to experiment cohorts, rewrites the request to variant-specific routes, and sets response headers for analytics tracking. Zero-latency feature flags without client-side flicker or layout shift.
Product teams running experiments on landing pages, checkout flows, or pricing pages where client-side A/B testing causes visible content shifts and inflates bundle size.
Single Next.js application serving multiple tenants with custom domains. Middleware resolves tenant from hostname, loads tenant configuration from Edge Config or database, and applies branding, feature flags, and routing rules per tenant. Shared codebase with tenant-isolated data.
B2B SaaS platforms where each customer needs a branded experience on their own domain while sharing the same underlying application and deployment infrastructure.
Route-level rendering decisions: marketing pages use ISR for edge-cached performance, dashboards use SSR for real-time data, documentation uses static generation for build-time completeness, and interactive widgets use client-side rendering for responsiveness. Each route declares its rendering strategy explicitly in the route segment config.
Applications with mixed content types — static marketing, dynamic dashboards, real-time feeds — that need optimal performance characteristics per page without a one-size-fits-all rendering approach.
Middleware executes at Vercel's CDN edge nodes on every request before it reaches the serverless function or static asset. It runs in the Edge Runtime — a V8 isolate with no Node.js APIs, no filesystem access, and a 1MB code size limit. Common patterns include geo-routing based on request headers (x-vercel-ip-country), authentication token validation with lightweight JWT verification, A/B experiment assignment via cookie-based cohort bucketing, and request rewriting to route traffic to different page variants without client-side redirects.
Keep middleware under 1MB and avoid heavy computation — it runs on every request including static assets. Use matcher config to restrict middleware to specific paths. Never call databases or external APIs from middleware; use Edge Config for pre-computed lookup data instead.
ISR serves a stale cached response instantly while triggering background regeneration based on the revalidate interval. On-demand revalidation exposes an API route that accepts webhook calls from CMS platforms (Contentful, Sanity, Strapi) to invalidate specific paths or tags immediately. Tag-based revalidation with revalidateTag() allows invalidating groups of related pages (e.g., all pages using a shared layout component) without enumerating individual paths.
Use on-demand revalidation for CMS-driven editorial content where publish latency matters. Use time-based revalidation for analytics dashboards and aggregate data pages where eventual consistency within 60-300 seconds is acceptable. Combine both: time-based as a safety net with on-demand for critical content changes.
Vercel's Image Optimization API automatically detects browser capabilities via the Accept header and serves WebP or AVIF formats. Images are resized on-demand based on the requested dimensions and device pixel ratio, cached at edge nodes globally, and served with immutable cache headers. The next/image component generates srcset attributes for responsive loading and uses native lazy loading with blur placeholders generated at build time.
Use next/image with explicit width and height to prevent layout shift. Configure remote patterns in next.config.js for external image sources instead of allowing all domains. Set image quality to 75 for photographs and 90 for text-heavy images. Never bypass next/image with raw img tags — you lose format detection, responsive sizing, and edge caching.
Every Git push creates an isolated deployment with a unique URL. Preview deployments run against pull request branches with environment-specific variables. Deployment protection rules gate production deployments behind team approval workflows. Promotion-based workflows allow deploying a tested preview deployment directly to production without rebuilding. Instant rollback reverts to any previous deployment in under 1 second by swapping the CDN pointer.
Require approval for production deployments with at least two reviewers. Enable deployment protection for staging environments to prevent accidental exposure. Use Vercel's Git integration to map branches to environments: main → production, develop → preview, feature/* → preview with protection.
Vercel Speed Insights collects real-user Core Web Vitals (LCP, FID, CLS, INP, TTFB) from production traffic segmented by route, device type, and geography. Conformance rules run at build time to enforce framework best practices — detecting common performance anti-patterns like synchronous scripts, unoptimized images, and excessive client-side JavaScript. Custom performance budgets in vercel.json define thresholds that fail builds when regression is detected.
Set Core Web Vitals budgets in vercel.json: LCP under 2.5s, CLS under 0.1, INP under 200ms. Monitor per-route performance, not just site-wide averages — a single slow route can hide behind healthy aggregate metrics. Use Conformance rules as a build gate to catch regressions before they reach production.
Middleware intercepts all requests at the CDN edge, reads the x-vercel-ip-country header to determine visitor geography, and rewrites requests to country-specific content variants. A fallback country ensures visitors from unmapped regions still get served. The middleware runs before any page rendering occurs, so the redirect is transparent to the user with zero additional latency.
// middleware.ts — runs at CDN edge on every request // Reads geo header → rewrites to localized route // Matcher restricts to marketing pages only // Fallback to 'en' for unmapped countries // Cookie override allows manual locale switching // // Pattern: geo header → country map → rewrite // No origin round-trip, no client-side redirect
Configuration for a Turborepo monorepo where shared packages (UI library, config, types) are consumed by the Next.js application. transpilePackages ensures shared packages are compiled correctly. Image remote patterns whitelist external CDN domains. Output configuration targets standalone mode for containerized deployments. Experimental features enable server actions and PPR for hybrid rendering.
// next.config.js — monorepo-aware configuration // transpilePackages: ['@acme/ui', '@acme/config'] // images.remotePatterns: CDN domains whitelist // output: 'standalone' for Docker deployments // experimental.serverActions: enabled // turbo.resolveAlias: shared package resolution
Edge Config stores feature flag definitions as a JSON document replicated to every CDN edge node. Reading Edge Config in middleware or server components evaluates flags with sub-millisecond latency — no origin database query, no external feature flag service round-trip. Flag changes propagate to all edge nodes within 300ms of update. Pattern supports percentage rollouts, user-targeted flags, and environment-scoped overrides.
// Feature flag evaluation at edge — no origin round-trip
// import { get } from '@vercel/edge-config'
// const flags = await get('featureFlags')
// Supports: boolean, percentage rollout, user targeting
// Propagation: <300ms to all edge nodes globally
// Fallback: default values when Edge Config unavailableCMS-driven pages with sub-second updates and global edge caching for peak performance.

“We went from dreading deployments to shipping three times a day. The editorial team can preview changes instantly, and our Lighthouse scores went from red to green overnight. Vercel with CloudForge was the best infrastructure decision we made.”
— Head of Engineering, Digital Media Company
Our frontend infrastructure team has deployed over 100 production Vercel projects spanning e-commerce storefronts, SaaS platforms, marketing sites, and internal tools. We are not just Next.js users — we contribute to the framework, understand the rendering pipeline internals, and debug ISR cache invalidation issues that most agencies attribute to "Vercel bugs." When your preview deployments break in a monorepo, when Edge Middleware silently fails on certain paths, or when your Lighthouse score craters after a dependency upgrade — we have seen it before and know the fix.
Where we differentiate is enterprise Vercel configuration. Solo developers use Vercel's defaults and ship. Organizations with 20+ engineers, multiple products, and compliance requirements need: Turborepo remote cache with scoped access tokens, environment variable governance preventing secret leakage into preview branches, deployment protection requiring multi-party approval for production, SAML SSO with SCIM-provisioned team membership, and cost alerting per project. We configure the organizational layer that the Vercel docs mention but never fully explain.
We pair with your engineering team to establish frontend infrastructure patterns that outlast our engagement. That means documented conventions for monorepo package boundaries, ISR revalidation strategies per content type, Edge Middleware patterns for cross-cutting concerns, and performance budget enforcement in CI. Your team ships faster during the engagement and maintains that velocity independently afterward.
