## What it is
A logic programming library for Clojure and ClojureScript implementing miniKanren with Prolog-like relational and constraint logic programming. It supports extensions such as cKanren and αKanren and is designed to be extensible to other logic programming forms.

## Use cases
- embed a miniKanren logic engine in Clojure programs
- solve relational and constraint logic problems
- run Prolog-style relational programming on the JVM
- write logic programs that compile to ClojureScript for the browser
- work through The Reasoned Schemer exercises in Clojure
- build custom logic programming extensions on a miniKanren core

## When to choose
- you need declarative relational or constraint logic programming in Clojure or ClojureScript
- you want a mature, well-maintained miniKanren implementation on the JVM
- you need unification and goal-based search integrated with your Clojure code

## When to avoid
- you need a full standalone Prolog system with ISO semantics
- your problem is better solved with plain functional programming without backtracking search
- you work outside the Clojure/JVM/JavaScript ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: interpreter, parser
- domain: programming-languages, developer-tools
- platform: jvm, cross-platform
- tags: logic-programming, minikanren, prolog, clojure, clojurescript, relational-programming, constraint-solving, algorithms
