Firebase Spark
Firebase Spark
Role
Auth + user database for every signed-in feature in the family.
Backs the Hono Worker at api.oriz.in and the per-site
<AccountPanel>.
Free tier
- Auth: unlimited Google / GitHub / email-link / anonymous users. 10K phone verifications / month.
- Firestore: 1 GiB storage, 50K reads/day, 20K writes/day, 20K deletes/day, 10 GiB egress/month.
- App Check: unlimited.
Card / subscription required?
NO. Spark plan does not require a billing account. Upgrading to Blaze would, which is exactly why the family rule is never enable Blaze.
Alternatives
Swap cost
High. Every site's <AccountPanel> reads from [data-oriz-account-*]
hooks wired into the @chirag127/firebase-init package. Schemas
migrate, Firestore security rules rewrite, and auth sessions don't
transfer.
Why this is our pick
Free tier is wide enough to never throttle if we honor the
never-hit-quotas rule. Google's auth UI works on day one. The whole
family already standardises on auth.oriz.in.
