- 100,000 operations/month
All Prisma ORM queries count as operations; the free tier resets at 100,000 per month across all databases in the account.
- 50 databases max
The free plan is capped at 50 databases total in the account (all quotas are shared across databases).
- 500 MB storage cap
Total storage across all free-tier databases is capped at 500 MB with no overage allowed on the free plan.
- No backups on free tier
Daily backups are not included on the free plan; backup retention is only available from the Starter plan ($10/mo) upward.
- No cache tag invalidations
Global cache tag invalidations are not available on the free or Starter tier; only available on Pro and above.
- Pooled connections capped at 10
Free tier allows only 10 pooled connections and 10 direct connections, versus 100/500/1000 on paid tiers.
- Community support only
Free tier users receive community support only; standard and premium support require Starter or Pro plans.
- GDPR compliance only
Free tier is GDPR-compliant but excludes HIPAA, SOC2, and ISO:27001 compliance available on higher plans.

Cache purge requests are limited to 5 per hour on the free plan, shared across all databases.
- Shared/unikernel infrastructure
Free tier runs on shared bare-metal unikernel infrastructure with no SLA guarantees unlike paid plans.
