BlockVault is a WordPress plugin, published by PerAstra and also listed on the official WordPress.org plugin directory (as "PerAstra BlockVault"), that lets WordPress professionals save blocks and block compositions built in the Gutenberg editor to a personal cloud library and reuse them on any other WordPress site. Rather than adding new block types like typical block-pack plugins (Kadence Blocks, Ultimate Addons for Gutenberg, GenerateBlocks), BlockVault captures the exact compositions a user builds — a hero section, pricing table, or CTA — and lets them insert an identical copy on any connected site in one click, with colors, fonts, and spacing automatically converted to inline styles so the block looks the same regardless of the active theme. It works with any Gutenberg-compatible theme, including Astra, Kadence, GeneratePress, and Twenty Twenty-Four, but is not compatible with page builders such as Elementor, Divi, Bricks, or Beaver Builder, which use their own data formats. The plugin can be used without an account in a local-only mode (blocks stored in the browser) or with a free or paid account for cross-site cloud sync. Paid plans are billed annually via Paddle and add unlimited blocks, more connected sites, custom-CSS capture, and priority support, with the top Agency tier aimed at teams managing many client sites.
