Mago/PHP toolchain/Carthage Software

A PHP toolchain, oxidized.

Mago is a static analyzer, linter, and formatter for PHP, written in Rust. Built for projects that have outgrown the patience of their tooling.

§ 01

Three tools, one binary

01 / Analyze

Static analysis

Find bugs, dead code, and impossible types before they ship. Compatible with Psalm and PHPStan annotations; understands generics, conditional types, and flow narrowing.

1.46s · 7M LOC

02 / Lint

Opinionated linting

A curated catalogue of rules for correctness, consistency, and clarity. Fix-on-save where safe. Quiet where it should be.

03 / Format

Formatter

A deterministic formatter that produces stable, conventional output. No configuration roulette, no debate. Drop in and move on.

Benchmarks

Measured against WordPress on the latest stable release of every tool. Lower is better; the "×" column shows how many times slower the slowest peer is compared to Mago. Numbers refresh from the php-toolchain-benchmarks dashboard (full mean / stddev / max / memory breakdown there), last updated 2026-04-15 02:47:37.

Install

[ INSTALL ]shell · macOS · Linux · WSL

curl --proto '=https' --tlsv1.2 -sSf https://carthage.software/mago.sh | bash

Or via Composer, Homebrew, Cargo, or a prebuilt Docker image.

§ 04

Three steps to first run

Install. One command. No PHP runtime required. Single static binary.
Initialize. Run mago init in your project root. Mago detects your layout and writes a mago.toml.
Run. Use mago analyze, mago lint, or mago fmt. Wire it into pre-commit, CI, or your editor.

§ 05

Try it without installing

The playground runs the full Mago analyzer in your browser via WebAssembly. Paste any PHP, share the result by URL.
