The short version
- Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; SQLite supports only serialized write operations; only one process can modify the database at any moment, limiting concurrent users
- They diverge on capability: PostgreSQL covers JSON/JSONB Support, SQLite covers Serverless Operation.

Both are used for transaction processing, data storage, application backend, reporting, data analytics, on those jobs the choice comes down to price and fit rather than capability.
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
PostgreSQL
- Requires manual scaling across multiple machines for very large deployments
- Performance tuning requires deep knowledge of database internals
- No built-in graphical admin interface; command-line tools are primary method
SQLite
- Supports only serialized write operations; only one process can modify the database at any moment, limiting concurrent users
- No multi-user support or granular access control; relies on file system permissions for security only
- Limited ALTER TABLE functionality cannot edit or modify columns in existing tables

Answered from the vendors’ own pages
PostgreSQL: Is PostgreSQL completely free?
Yes. PostgreSQL is completely free and open source with no licensing fees or restrictions on use.
SourceSQLite: Is SQLite free and open source?
Yes, SQLite is open source and in the public domain. The complete source code and binaries are free to download and use for any purpose without restrictions.
SourcePostgreSQL: What platforms does PostgreSQL run on?
PostgreSQL runs on all major operating systems including Linux, Windows, macOS, BSD, and commercial Unix variants, and has been proven highly scalable managing terabytes to petabytes of data.
SourceSQLite: How does SQLite work and what is its design?
SQLite is a self-contained, serverless SQL database engine that reads and writes directly to disk files. It requires no separate server process and runs within your application, making it ideal for embedded systems and local storage.
SourcePostgreSQL: What procedural languages are supported?
PostgreSQL supports stored functions and procedures in multiple languages including PL/pgSQL, Perl, Python, Tcl, Java, JavaScript, R, and Rust.
SourceSQLite: What are SQLite's limitations for scaling?
SQLite does not support true multi-user concurrency. Only one process can write to the database at a time, and it lacks user management and access control features. It is designed for small to medium projects, not enterprise applications with many concurrent users.
SourcePostgreSQL: What is ACID compliance in PostgreSQL?
PostgreSQL has been ACID-compliant since 2001, ensuring data integrity through atomicity, consistency, isolation, and durability guarantees for all transactions.
SourceSQLite: Can I use SQLite for production web applications?
SQLite can work for single-server web applications with modest concurrency needs. However, it lacks features like user management, granular security, and sophisticated query optimization needed for large-scale applications.
SourcePostgreSQL: Does PostgreSQL support JSON data?
Yes. PostgreSQL supports JSON and JSONB data types for storing and querying JSON documents, along with XML and other document formats.
