About PerfLocale

A multilingual plugin built from scratch with care for performance, security, and WordPress standards.

Why PerfLocale exists

Multilingual WordPress sites shouldn't have to choose between features and speed. PerfLocale was built from the ground up to handle translation without adding unnecessary weight to your pages.

Every architectural decision is guided by three principles: keep it fast, keep it safe, and do it the WordPress way. No third-party libraries. Every line follows WordPress Coding Standards.

⚖

Thoughtful performance

PerfLocale uses a 3-layer caching architecture that serves most operations from memory. Batch preloading prevents repeated database queries. Hooks and filters are registered conditionally - if a feature isn't needed on a page, its code doesn't run.

Independent benchmarks show less than 5ms overhead per page. We measure this regularly to make sure it stays true - see the published numbers, with the scripts so you can verify on your own site.

⚡

Security as a foundation

Security is built into every layer of PerfLocale, not added as an afterthought. We follow WordPress security best practices throughout:

  • All database operations are protected against injection attacks
  • All output is sanitized to prevent cross-site scripting
  • All form submissions and API requests are verified for authenticity
  • All actions are permission-checked so users can only do what they're allowed to
  • All external connections use HTTPS and are validated to prevent unauthorized requests
🔒

Built for developers

PerfLocale provides 120+ action and filter hooks, a full REST API, WP-CLI commands, and a clean addon architecture. Extending or customizing PerfLocale should feel natural to any WordPress developer.

The addon system auto-detects compatible plugins and themes. If you need something custom, implementing the AddonInterface and dropping a file in the addons/ directory is all it takes.

🛠

Free and open source

PerfLocale is licensed under GPL-2.0+ and is free to use, modify, and distribute. There are no premium tiers, no upsells, and no artificial feature gates. Every addon and integration is included.

Contributions, bug reports, and feature requests are always welcome.
