Open local folders, connect remote sites, edit source, preview pages, inspect rendered elements, update plain text directly from the preview and keep project tools close without leaving the Mac desktop.
The Links palette keeps local projects and remote connections together. Open a folder, jump into a saved site, configure a connection or reveal files in Finder.
Workspace details →
Inspect mode adds hover overlays, persistent selection, DOM breadcrumbs, box model, filtered computed styles and source reveal. Edit Text mode lets plain-text elements be changed from the preview and written back to the file with undo.
Inspector workflows →Switch between source-only, preview-only or split view. Split can be vertical or horizontal, live view can sit on top, and PHP preview can stage files through your own FTP, FTPS or SFTP server.
Preview workflows →
Floating Mac palettes help you inspect the DOM, tune styles, insert reusable snippets, browse elements and collect colors while the editor remains focused.
