SQLite
Database & Data Management
Small, fast, self-contained SQL database engine
- From
- Free
- Rated
- -
The short version
- Each has a real cost: SQLite supports only serialized write operations; only one process can modify the database at any moment, limiting concurrent users; DuckDB client-server setup remains in beta and not recommended for production distributed scenarios
- They diverge on capability: SQLite covers Serverless Operation, DuckDB covers In-process Execution.
Where they differ
Only the attributes on which SQLite and DuckDB actually diverge.
Identical on both: starting price (Free), pricing model (open-source), free tier (Yes), user rating (Not yet rated), category (Database & Data Management).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
SQLite
- Supports only serialized write operations; only one process can modify the database at any moment, limiting concurrent users

- Limited ALTER TABLE functionality cannot edit or modify columns in existing tables
DuckDB
- Client-server setup remains in beta and not recommended for production distributed scenarios

Answered from the vendors’ own pages
SQLite: 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.
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.
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.
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.
