First paid plan
Blaze — Pay as you go (no flat price shown). SQL Connect: Cloud SQL for PostgreSQL has a 3 month no-cost trial (limit 1 per project), then 'starting as low as $9.37/month'. Remote Config fetch requests: no-cost up to 100,000 per day per project, then $0.06 / 10K requests (100,001 to 10,000,000 per day) and $0.01 / 10K above that; the page says this pricing takes effect starting September 1, 2026.
EU / data region
The pricing page does not say which locations Firebase runs in. It does say Cloud Storage no-cost quotas only apply to buckets in us-central1, us-west1 and us-east1, so an EU bucket gets no free storage quota.
Notable pricing note
Remote Config fetch requests are billed above 100,000 per day per project; the page says this pricing takes effect starting September 1, 2026.
