It's a split decision.
Choose PostgreSQL if you need an open-source database and can plan and operate the rest of your stack. Its pricing information lists it as free, with no published seat or usage limits. Choose Supabase if you want Postgres bundled with authentication, storage, APIs and functions. Its free tier has usage caps; Pro is $25 per month, and paid-plan overages can add costs. Supabase is a backend platform built around Postgres, not a separate database engine.

02Pricing compared
PostgreSQL is listed as free, with no paid plans and no published seat or usage limits. Supabase has a free tier, but it is capped at 50,000 monthly active users, 500 MB of database storage per project, 5 GB of egress and 1 GB of file storage. The free tier allows two active projects, which pause after a week of inactivity.
Supabase Pro costs $25 per month and includes 100,000 monthly active users, 8 GB of disk per project, 250 GB of egress and 100 GB of file storage. Overages can add up: the pricing page lists $0.00325 per extra monthly active user and $0.09 per GB of egress on Pro and Team. Compute, extra projects and other add-ons can also cost more. Annual prices are not published.
03Features and depth
PostgreSQL is the database in this comparison: an open-source object-relational system with more than 35 years of active development. Its homepage cites reliability and performance, and points users to documentation and community resources. The published information does not list specific database features or limits beyond that, so we would not treat the description as a full technical spec.
Supabase is a backend platform built around Postgres, not a competing database engine. Each project includes a portable Postgres database, built-in authentication and Row Level Security. Supabase also bundles file storage, ready-to-use REST APIs, Edge Functions and realtime syncing and event broadcasts. Its tools cover vectors, scheduled jobs and message queues, too. That bundle can reduce the number of separate services a team needs to choose, but it also means comparing Supabase’s platform limits and add-on prices—not just the underlying database—with PostgreSQL’s free software.
04Ease of use and learning curve
Supabase offers a more bundled starting point: its projects include auth, storage and REST APIs, and it provides Edge Functions without deploying or scaling servers. That may suit teams that want backend services alongside Postgres, but the free-tier caps and paid-plan overages still need attention.
PostgreSQL’s official documentation and community resources cover installation, use and learning. The published review notes that its flexibility asks teams to plan their data. The trade-off is scope: PostgreSQL is the database, while Supabase supplies a broader backend platform. If you choose PostgreSQL, plan how the rest of your stack will cover the services Supabase bundles.
Questions people ask
Is there anything better than Supabase?
There is no single answer in the published information. PostgreSQL may fit better if you want open-source database software with no published seat or usage limits and can plan the rest of your stack. Supabase may fit better if you want Postgres bundled with auth, storage, APIs and functions.
Can Postgres handle 1 billion rows?
The published PostgreSQL information does not publish a row-count limit or a billion-row benchmark, so we can’t confirm capacity from these sources. PostgreSQL’s homepage cites reliability and performance, but that is not a guarantee for a specific workload. Validate your schema, queries and operating setup against your requirements.
What are the key differences between PostgreSQL and other databases?
The published information describes PostgreSQL as an open-source object-relational database with more than 35 years of active development. It does not provide a feature-by-feature comparison with other database engines. Supabase is a different kind of product: a backend platform built around a portable Postgres database, with additional services such as auth and storage.
Is PostgreSQL obsolete?
The published information does not suggest that: PostgreSQL’s homepage describes more than 35 years of active development and points to current documentation and community resources. It does not provide a release schedule or a full comparison with newer databases, so those details would need checking separately.
