About René Hermenau
I'm René Hermenau, founder of WP STAGING. I've been developing WordPress infrastructure software since 2013, building WP STAGING since 2015, and publishing code on GitHub since 2011.
WP STAGING started as a developer project to solve a problem I kept running into during client work: cloning and migrating WordPress sites safely without breaking serialized data, file paths, media references, or database relationships.
Today, WP STAGING is built and maintained by a team of more than 10 people. The free plugin is used on 100,000+ active WordPress installations, and WP STAGING Pro powers backup, migration, staging, and deployment workflows for agencies, hosting providers, ecommerce stores, and professional WordPress teams.
I'm still hands-on with the codebase, architecture, and technical direction of the product. Much of my work focuses on reliable database exports, memory-efficient processing on large WordPress sites, safe restore workflows, staging-to-production deployments, and reducing the risk of partially written files or database tables during migrations.
On this author page, you'll find technical articles, documentation, and product guides I have written, reviewed, or helped shape with the WP STAGING team.
When you touch code, leave it 10% better than before and write a test.
If you're stuck on a WP STAGING question, start with the documentation. If you hit a bug, file it on GitHub. Our team reads everything that lands there.
