Firebase Hosting to Vercel

When we first launched azarr.tech, Firebase Hosting was the simplest way to deploy our Next.js static site. It was fast, free, and handled HTTPS automatically. But as our content strategy evolved and SEO became critical for B2B lead generation, Firebase's limitations became increasingly apparent—especially when combined with the broader billing issues we were experiencing with Google Cloud.

The problem with static hosting for dynamic B2B sites

Firebase Hosting is fundamentally a static file server. While you can deploy Next.js apps to Firebase, you lose Next.js's most powerful features: Incremental Static Regeneration, Edge Middleware, and Server Components. For a B2B platform where content freshness, personalization, and performance directly impact conversion rates, this was a dealbreaker.

• Content updates required full site rebuilds (15+ minutes, multiple times daily)
• No incremental static regeneration meant every page rebuild for every change
• Limited preview environments made client feedback cycles slow and error-prone
• No integrated analytics beyond basic request logging
• Poor image optimization without manual CDN configuration
• Cold start delays for dynamic routes
• Compounding the issue: The same Google Cloud billing problems affecting our backend also impacted Firebase Hosting—our frontend was part of the same platform ecosystem with billing disputes and support delays

We were publishing new case studies, blog posts, and technical documentation constantly—and every update cost us 15 minutes of downtime and SEO penalties for slow reindexing. Add the billing uncertainty from Google Cloud, and we had a perfect storm of operational friction.

Why Vercel won: Built for modern Next.js

1. Incremental Static Regeneration (ISR)

Vercel's ISR allows us to update specific pages without rebuilding the entire site. When we publish a new case study, only that page regenerates—the rest of the site stays live. This reduced our average build time from 15 minutes to under 30 seconds for most updates, and eliminated downtime entirely. Our content team can now publish changes instantly, without scheduling around developers.

2. Edge Functions for Personalization

B2B websites need to serve different content to different stakeholders—a CTO sees technical deep-dives, while a CFO sees ROI calculators. Vercel Edge Functions let us run JavaScript at the edge, personalizing content based on geolocation, device type, or session data without any latency penalty. Firebase offered no equivalent.

3. SEO Superpowers

Vercel's integrated SEO tools, pre-rendering optimization, and metadata handling are best-in-class. We saw Core Web Vitals scores improve from 62 to 91 (Lighthouse). Time-to-Interactive dropped from 3.4s to 1.8s. The impact on organic traffic was immediate and measurable—B2B organic search traffic increased 85% in three months.

4. Preview Deployments and Collaboration

Every pull request gets a unique preview URL. Our content team can preview blog posts, our marketing team can test landing pages, and our clients can review case studies—all before anything goes to production. This cut review cycles from 3 days to 4 hours and eliminated costly production mistakes.

5. Built-in Analytics and Speed Insights

Vercel Analytics provides real-time performance data broken down by page, region, and device type. We identified that European clients were experiencing 200ms slower loads and optimized specifically for them. Firebase offered no comparable insights.

6. Web Vitals Monitoring

Vercel's Web Vitals monitoring alerts us when any page drops below acceptable thresholds. This proactive approach helped us maintain a consistent experience for enterprise clients, who demand reliability above all else.

7. Decoupling from GCP Billing Issues

Perhaps most importantly, moving our frontend to Vercel meant we could completely decouple our web presence from Google Cloud. Even after migrating our backend to AWS, our Firebase Hosting was still connected to the GCP billing system. By moving to Vercel, we eliminated the final link to Google Cloud's problematic billing infrastructure. Our frontend is now hosted on a platform built for Next.js, with transparent pricing and responsive support.

The migration: Practical implementation

1. Setup Vercel Project: Connected GitHub repository and configured environment variables
2. Migrate Next.js Config: Updated `next.config.js` for Vercel optimization (images, caching, headers)
3. Configure Edge Middleware: Implemented geolocation-based content routing and authentication checks
4. Set Up Preview Deployments: Configured Vercel for automatic preview environments on PRs
5. DNS Migration: Switched DNS from Firebase to Vercel with zero downtime using blue-green deployment
6. Analytics Integration: Added Vercel Analytics and Google Search Console integration
7. Final Cleanup: Removed the Firebase Hosting configuration and verified no remaining Google Cloud dependencies
