Full-stack web hosting on Google Cloud. Not on the free Spark plan. Blaze adds a $300 credit if eligible.
Sniffed 4d ago Card required#hosting#firebase#google-cloud#cloud-run#nextjs#paas#full-stack
App Hosting needs the pay-as-you-go Blaze plan, so budget for a bill. Firebase App Hosting deploys full-stack web apps onto Google Cloud, using Cloud Build and Cloud Run underneath, and ships new versions as rollouts. The forum questions I found include Next.js and Flask apps. It is not available on the no-cost Spark plan. You need the pay-as-you-go Blaze plan, which includes a $300 free credit if your account is eligible. App Hosting lists outgoing bandwidth free up to 10 GiB a month, then $0.20 per GiB uncached or $0.15 per GiB cached, and storage free up to 5 GB, then $0.10 per GB. Cloud Run, Cloud Build, Artifact Registry, Cloud Logging and Secret Manager are billed separately under Google Cloud pricing. I found no G2 or Capterra data, and the forum evidence is mixed, including an r/Firebase thread titled "I do not recommend Firebase App Hosting".

👍 Good boy
+The allowances are published. Outgoing bandwidth is free up to 10 GiB a month and storage up to 5 GB, so you can estimate a small app before you deploy.
+Eligible Blaze accounts get a $300 free credit, which you can use to test a real app before paying.
+Cached traffic is cheaper than uncached: $0.15 per GiB against $0.20 per GiB after the free allowance.
+Costs map onto named Google Cloud services (Cloud Run, Cloud Build, Artifact Registry, Cloud Logging, Secret Manager), so you can see each part of the bill in Google Cloud billing.
+A free path exists for static sites through the separate Firebase Hosting product, which lists 10 GB of storage and 360 MB a day free.
👎 Watch out
−App Hosting is not on the Spark plan. You must move to Blaze and attach a billing account, so there is no card-free free tier for it.
−A long-time Firebase user posted in r/Firebase in 2025 under the title "I do not recommend Firebase App Hosting", after about 3 years on Firebase. I saw only the excerpt, so I cannot say what drove it.
−Billing is spread across services. An r/googlecloud poster who deployed with App Hosting asked about Cloud Run tier 2 billing, because the service uses Cloud Build and Cloud Run underneath.
−Builds fail in ways people ask about on Stack Overflow, including a Flask app where Cloud Build chose the Node.js buildpack and a Next.js rollout that failed on a build error.
−Bandwidth past the 10 GiB allowance is $0.20 per GiB uncached, which is ten times Fly.io's $0.02 per GB for North America and Europe.
−Two r/nextjs threads show the cost side. One commenter suggested Coolify or Docker for $5 a month, and one poster reported about 27 euros a month for roughly 500 monthly views on Cloud Run. Those threads cover Cloud Run, not App Hosting alone.
−Outside evidence is forum posts only. I found no G2 or Capterra reviews, so the quality signal is weaker than for other hosts in this directory.
The catch
App Hosting is not available on the no-cost Spark plan. You need the Blaze plan, which is pay as you go and attaches a billing account. The pricing page says Blaze includes $300 of free credit for eligible accounts.
Within App Hosting itself, outgoing bandwidth is free up to 10 GiB a month and then $0.20 per GiB uncached or $0.15 per GiB cached, and storage is free up to 5 GB and then $0.10 per GB. Those are the App Hosting lines only. Cloud Run, Cloud Build, Artifact Registry, Cloud Logging and Secret Manager are billed separately under Google Cloud pricing, and the compute behind your app is where most of a bill is likely to come from.
Set a budget alert in Google Cloud before you deploy anything. An r/googlecloud poster who deployed with App Hosting asked about Cloud Run tier 2 billing, and a r/nextjs poster reported about 27 euros a month for roughly 500 monthly views on Cloud Run. The second case is Cloud Run, not App Hosting alone.
Firebase Hosting, which lists 10 GB of storage and 360 MB a day free, is a separate product. I did not read whether Blaze needs a card to enable, so the card field is unknown, and I found no commercial-use statement.

Common questions
Is Firebase App Hosting free?
Not on the Spark plan. It needs Blaze, which is pay as you go and includes a $300 credit for eligible accounts. Some usage is free each month: 10 GiB of outgoing bandwidth and 5 GB of storage.
What else will I be billed for?
Cloud Run, Cloud Build, Artifact Registry, Cloud Logging and Secret Manager, billed under Google Cloud pricing.
Is there a free option for static sites?
Firebase Hosting is a separate product that lists 10 GB of storage and 360 MB a day free.
What do developers say about it?
Forum evidence is mixed and thin. One long-time Firebase user posted that they would not recommend it in 2025, and Stack Overflow has questions about failing builds. I found no G2 or Capterra reviews.
How does bandwidth pricing work?
After 10 GiB a month, outgoing bandwidth is $0.20 per GiB uncached or $0.15 per GiB cached.
