How it started
The WordPress page builder Page Builder Sandwich is built by Neil Lock and developed, sold and supported by Zinn Digital® Ltd, his company. Its history reaches back to 2015, yet the current version 6 was rebuilt from scratch by the Zinn Digital® team. Like the other WordPress plugins Neil builds, it is made to WordPress.org's standards and kept up by the team behind the Zinn Digital® hosting.
The problem
Page builders have a habit of slowing pages down and holding content hostage. Every page loads the builder's whole stylesheet and script, and the markup is wrapped in layers of builder-specific HTML. Turning such a builder off leaves shortcodes all over the site.
What he built
So Page Builder Sandwich saves ordinary WordPress blocks, not shortcodes or a private format; the theme and SEO plugins read them, and pages keep their content without the plugin. Styles are loaded per page, only for the blocks present, from the site itself, and the Interactivity API of WordPress replaces jQuery for interactive blocks. The finished HTML has neutral class names and carries no generator tag or comment pointing back to the builder. He added Sandwich Studio, a full-screen editor with layers, undo history and a command palette, a free accessibility checker, and an MCP server whose 150 tools let Claude and other agents build pages as the signed-in user.
The hard parts
Rebuilding from scratch meant looking after existing sites: pages made with versions 4 and 5 are converted to blocks in the background and keep exactly the look they had. On 1 October 2026 version 6.28.0 was installed on a clean WordPress test site and measured: plus 0.5 kB, no requests to other servers, and Lighthouse performance on phones still 100. Equally important was caching: front-end files keep their addresses across versions, so a cached page never breaks after an update.
Milestones
Early dates: the free Lite version was announced on 14 January 2016, version 3.0 followed on 17 October 2016, and version 4.0 came out on 16 January 2017 for its first birthday. Version 6 ships 44 free blocks and 20 free kits, with Pro bringing the totals to 112 blocks and 28 kits.
What's next
Work continues release by release, and the changelog lists every version 6 release; the newest, 6.36.31, is tested with WordPress 7.1. Recent versions added a mobile menu bar designer, per-row sticky headers, OKLCH palette shades and style conditions for print, dark schemes and reduced motion.
