A PHP library that auto-discovers installed PSR-17, PSR-18, and HTTPlug HTTP client and message factory implementations, with a Composer plugin that can auto-install them. It lets library authors code against standard interfaces without forcing a specific HTTP implementation on their users.

Use cases

• find installed psr-18 http client in a php project
• auto-discover psr-17 response factory implementation
• write an sdk without forcing a specific http client on users
• resolve between guzzle and nyholm psr7 implementations
• auto-install http client dependencies via composer plugin

When to choose

• you are a PHP library or SDK author who needs an HTTP client without hard dependency on a specific implementation
• your project may contain multiple PSR-7/17/18 implementations and needs deterministic selection
• you want Composer to automatically install a missing HTTP implementation

When to avoid

• your application already directly depends on one specific HTTP client and needs no abstraction
• you are not working in the PHP/Composer ecosystem
• you need an actual HTTP client rather than discovery of one
