Where each one falls short

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

Coder

  • Premium plan pricing is not published and requires contacting sales
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls

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
