Where each one falls short

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

Firebase Realtime Database

  • The no-cost Spark plan caps storage at 1 GB, downloads at 10 GB per month and simultaneous connections at 100
  • The Spark plan does not support multiple databases in a project
  • Even on the paid Blaze plan simultaneous connections are capped at 200,000 per database
  • Billing is by data transferred out at $1 per GB plus $5 per GB stored, so chatty clients cost more than the data volume suggests

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month
