The short version

  • Each has a real cost: Firebase spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes; Parse Server deployment complexity and scaling challenges require operational expertise
  • They diverge on capability: Firebase covers Real-time Database, Parse Server covers GraphQL API.
  • Prices and features above were last checked on 30 August 2026.

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)

Parse Server

  • Deployment complexity and scaling challenges require operational expertise
  • Requires database management skills for MongoDB or PostgreSQL administration
  • Smaller community and ecosystem compared to Firebase or cloud alternatives
  • Query depth bypass vulnerability allowing denial-of-service attacks via complex REST/GraphQL queries
  • Stored XSS vulnerability through SVG file uploads requires patching
