Firebase provides real-time database, authentication, hosting, cloud functions, and analytics. The original BaaS platform. Still popular despite Supabase's rise.

Reviewer scorecard
“Authentication, Firestore, and Cloud Functions get you from zero to production fast. The free tier is generous.”
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“Firestore's limitations become painful at scale. Supabase with Postgres is the modern alternative.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Firebase defined BaaS but Supabase's open-source, Postgres-based approach is the future.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
