**Execute PHP closures in true parallel** — native `pcntl_fork` with zero dependencies, no daemon, no binary, no serialization.

---

Features
--------

[](#features)

- **True Parallel Execution** — `pcntl_fork` runs closures in separate processes simultaneously
- **Zero Dependencies** — only PHP 8.3+ with `ext-pcntl` and `ext-posix` (built-in)
- **No Daemon, No Binary** — no external process to install, start, or manage
- **No Closure Serialization** — forked processes inherit parent memory; closures run as-is
- **Simple async/await API** — familiar Promise-like interface with global helpers
- **Promise Chaining** — chainable `then()`, `catch()`, and `finally()` methods
- **Cross-platform** — fork mode on Linux/macOS, automatic sequential fallback on Windows
- **Benchmark Mode** — optional per-task metrics (execution time, memory, CPU)

Requirements
------------

[](#requirements)

- PHP 8.3+
- ext-pcntl (Linux/macOS — built-in, enables fork mode)
- ext-posix (Linux/macOS — built-in, enables fork mode)

> **Windows?** Parallite works on Windows in sequential fallback mode (no `pcntl_fork`). Parallel execution requires a Unix-like OS.

Installation
------------

[](#installation)

```
composer require parallite/parallite-php
```

That's it. No binary to download, no daemon to start, no post-install scripts.
