SWI-Prolog is a comprehensive, open-source (BSD-2) implementation of the Prolog logic programming language, implemented in C and Prolog with many extensions. It runs on Linux, POSIX systems, macOS, and Windows, includes a native GUI toolkit (XPCE), and offers a WASM build for browsers and Node.js.

Use cases

• run prolog programs from the command line
• learn logic programming
• build rule-based reasoning and business rule validation systems
• natural language processing with definite clause grammars
• semantic web and RDF linked data processing
• embed a prolog interpreter in a browser or node app via wasm
• solve constraint and graph processing problems

When to choose

• you need a mature, well-documented Prolog implementation with an active community
• you want cross-platform Prolog with a GUI toolkit, debugger, and profiler included
• you need logic programming for reasoning, NLP, or rule validation tasks
• you want to run Prolog in the browser or Node.js via WASM

When to avoid

• you need a general-purpose language for mainstream application development
• your team has no experience with logic programming paradigms
• you need strict license compliance review, as the repository license is not a standard SPDX entry
