Moxzi Alpha Released as Self-Hosted Motoko Toolchain for Off-Chain and On-Chain Use

Developers have released the public alpha of Moxzi (v0.1.0-alpha.1), a Motoko compiler written in Motoko and compiled to WebAssembly. The toolchain enables self-hosted compilation across local CLI, on-chain canisters, off-chain server runtimes, and web browsers.

A self-hosted Motoko toolchain named Moxzi has launched its first public alpha version (0.1.0-alpha.1). The compiler is written in Motoko and compiled to WebAssembly by itself, designed to operate across four targets: a local command-line interface, an on-chain builder canister, an off-chain server runtime (`moxzid`), and inside browser tabs (`moxzi-web`).

According to the developers, Moxzi was built to support trustless, auditable on-chain builds and to enable Motoko actor models outside the Internet Computer mainnet. When executed on-chain, the builder canister utilizes an ICP escrow process to cover execution costs, refunding the difference after compilation completes. Every artifact produced by the compiler references the compiler build by hash for verification.

In benchmark details shared with the release, the compiler self-compiled on-chain across 169 source files, generating a 5.65 MB WebAssembly binary in approximately one hour of block time under mainnet execution limits. The project reports matching Motoko language compatibility up to version 1.14.1, though off-chain environments do not support threshold signature certificates or `@dfinity/agent`'s Actor pattern.

Moxzi is distributed under the Business Source License (BSL) 1.1, which permits free use for non-commercial projects, testing, and evaluation, while requiring a commercial license for production deployment. Each released version is scheduled to transition to the Apache-2.0 license four years after publication.
