Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Firebase

  • Spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes
  • Spark plan restricts to 100 concurrent database connections
  • Spark plan limits Firebase Studio to 3 workspaces maximum
  • Document size capped at 1 MiB per document
  • Transaction time limited to 270 seconds with 60-second idle expiration
  • Maximum 100 databases per project (increase requires support request)

Prisma

  • Prisma Postgres is billed per operation, with the free tier at 100,000 operations and 500 MB of storage
  • Starter at $10 a month includes 1M operations then charges $0.0080 per 1,000
  • Storage overage runs from $2.00 per GB on Starter down to $1.00 per GB on Business, so the unit cost depends on the plan
  • Accelerate charges separately per operation and per GiB of query egress beyond the first 1 KiB
  • Cache tag invalidations are not included below the Pro plan and are billed per thousand above it
