This project provides high-level and low-level TypeScript bindings for the [Z3 theorem prover](https://github.com/Z3Prover/z3). It is available on npm as [z3-solver](https://www.npmjs.com/package/z3-solver).

z3

Optional Node.js Z3 WebAssembly adapter and allowlisted workflow fixture for CAVE formal reasoning.

z3-solver fork used in js-randomness-predictor

Formal verification for TypeScript — prove your code is correct for all inputs using Z3

A Javascript wrapper with a Z3-ish API for SMT-LIB 2.0, the language of Satisfiability Modulo Theories solvers

SWI-Prolog 10.1.4 + Z3 4.16.0 in a single WebAssembly binary. Zero dependencies. Foreign predicates in JS, CLP(FD), Z3 SMT solving from Prolog via C FFI, ergonomic query API.

Neurosymbolic verification engine - MCP server for formal reasoning with Z3 and SWI-Prolog (WASM)

Formal verification tools for MUSUBIX - Z3 integration, precondition/postcondition verification, and EARS-to-SMT conversion

CLI for scaffolding Z3 Stack applications (TanStack/Next.js + Convex + Better Auth)

This directory contains JavaScript code to automatically derive TypeScript bindings for the C API, which are published on npm as [z3-solver](https://www.npmjs.com/package/z3-solver).
