Integration boundaries
Decap CMS wraps a Git content workflow and needs a configured backend. ReCopyFast does not create commits or pull requests, and it does not replace repository-based review when that history is the required source of truth.
ReCopyFast can be added across different site stacks because its integration is a script, but installation requires permission to add a script and a compatible Content Security Policy (CSP). It edits existing authored copy; it does not build pages or migrate a site. Published edits are applied in the visitor's browser after the page loads. Visitors without JavaScript, and crawlers that do not render JavaScript, see the original HTML copy, so put SEO-critical copy in the site's source as well.
