WordPress plugins · open source · production-grade

Free WordPress plugins from a 20-year engineer.

Open-source WordPress plugins engineered by Kevin Champlin at Champlin Enterprises. Senior-engineering quality. MIT or GPL. No bait-and-switch upsells, no AI credits meter, no per-seat tax. Build with them, fork them, ship them.

Each plugin is publicly auditable, PHPUnit-tested, namespaced PSR-4, and built to Plugin Check + WP.org review standards. Use them as-is; or hire me to build something custom for your stack.
