Firebase Hosting vs Vercel for your project

This is usually a framework-and-ecosystem decision more than a hosting one. Vercel is the default for Next.js and other framework apps with Git-based CI/CD; Firebase Hosting is the default if the rest of your stack — auth, database, functions — already lives in Firebase or Google Cloud. Both handle plain static sites fine, but neither was designed around that as the primary case.

How they compare

	Firebase Hosting	Vercel
Deploy method	Firebase CLI (firebase deploy) after firebase init	Git push triggers a framework-aware build automatically
Free tier	Generous storage and daily transfer allowance	Generous for personal/non-commercial use
Custom domain	Free, SSL issuance can take up to a day	Free, included
Build/CI required	No build step for plain HTML, but CLI + project setup needed	Built around Git CI/CD; no native manual drag-and-drop flow
Best for	Teams already on Firebase or Google Cloud	Framework apps (especially Next.js) with per-branch previews

When to choose Firebase Hosting

If your app already depends on Firebase Auth, Firestore, or Cloud Functions, Hosting keeps everything under one project and one bill. It's also a fine standalone choice for static content — solid CDN, free SSL — if you're comfortable with the CLI.

When to choose Vercel

Vercel is the stronger choice the moment there's a real framework and build pipeline involved, particularly Next.js, where the two are built for each other. Git push triggers an automatic build, every branch gets its own preview URL, and the whole workflow is designed around iterating on a framework app, not just serving fixed files. Usage-based pricing on paid tiers is worth watching if traffic spikes, though.

If you just need to host static files

Neither of these is built with plain static files as the primary use case — Firebase wants the CLI and a Google Cloud project, Vercel wants a Git repo and a framework it can detect. If your project really is just HTML, CSS, and JS with no build step, that's more infrastructure than the job needs. Flaash covers that narrower case directly: drag a folder or .zip into the browser and it's live immediately, no CLI, no Git, no build detection. The tradeoff to know going in: Flaash doesn't support custom domains yet, where both Firebase Hosting and Vercel do, free, out of the box.

Frequently asked questions

Can I deploy a plain static site to Vercel without Git? Vercel is built around Git-connected deploys; there isn't a polished manual upload flow for a static folder the way there is with a purely upload-based host.

Does Firebase Hosting support preview URLs per branch like Vercel? Firebase has preview channels you can trigger via the CLI, but it isn't automatic on every Git push the way Vercel's per-branch previews are by default.

Which is cheaper at scale? It depends on traffic pattern. Firebase's free tier is generous but usage-based beyond it; Vercel's paid usage-based pricing can spike under high traffic. Neither is a fixed-cost guarantee once you're well past free-tier limits.
