Supabase vs Apache Cassandra

Postgres + auth + storage + realtime meets the distributed database that scales like a dream but queries like a nightmare. Here's our take.

Supabase

Nice Pick

Postgres + auth + storage + realtime. The Firebase that doesn't lock you in.

Pros

• Open source
• Generous free tier
• Full Postgres
• Auth built-in
• Realtime

Cons

• Newer ecosystem
• Less documentation
• Some rough edges

Apache Cassandra

The distributed database that scales like a dream but queries like a nightmare.

Pros

• Massive horizontal scalability with no single point of failure
• Excellent write performance for time-series and IoT data
• Flexible schema design that evolves without downtime

Cons

• Complex querying with limited JOIN support
• Steep learning curve for data modeling and tuning

The Verdict

Use Supabase if: You want open source and can live with newer ecosystem.

Use Apache Cassandra if: You prioritize massive horizontal scalability with no single point of failure over what Supabase offers.

The Bottom Line

Supabase wins

Postgres + auth + storage + realtime. The Firebase that doesn't lock you in.
