<b>Supabase vs Firebase: SQL freedom or Google's walled garden?</b>

<b>Supabase vs Firebase: SQL freedom or Google's walled garden?</b>

For webmasters building tools on the side, the lock-in question is everything.

Supabase
👍 Real Postgres — your data is portable, SQL queries you already know
👍 Generous free tier, open-source, self-hostable escape hatch
👎 Realtime and edge functions less mature than Firebase's
👎 You manage more of the database mindset yourself

Firebase
👍 Realtime sync and auth are battle-tested at massive scale
👍 Tightest mobile SDKs and instant hosting
👎 NoSQL document model makes relational data painful
👎 Pay-per-read billing can surprise you, and you're Google-locked

Verdict: Pick Supabase if you think in SQL and want portable data. Pick Firebase if you need bulletproof realtime sync and live in Google's stack.

Best for: Supabase for SQL-minded indie builders, Firebase for realtime mobile apps.
