README

Peek gives editorial teams field-by-field diff comparison, side-by-side visual preview, and coordinated multi-entry releases for Craft CMS 5.

Features

Field Diff — Side-by-side comparison of every field between a draft and its live entry, with syntax-highlighted changes
Visual Preview — Two-pane iframe preview showing live vs. draft with synchronized scrolling
Releases — Group multiple drafts into a release and publish them atomically (all or nothing)
Scheduled Publishing — Set a future date and let Peek auto-publish via cron
Dashboard — Overview of pending drafts, stale drafts, and active releases across the site
Entry Sidebar — See changed field count, diff link and release membership in the draft editor, and add the draft to a release from there

composer require justinholtweb/craft-peek
php craft plugin/install peek

To enable scheduled releases, add a cron job that runs every minute:

* * * * * /path/to/craft peek/scheduler/check

Permission	Description
Access Peek	View the Peek CP section
View diffs	View field-by-field diff comparisons
Manage releases	Create, edit, and manage releases
Publish releases	Publish releases (apply all drafts)
Schedule releases	Set scheduled publish dates
Delete releases	Delete releases
Manage Peek settings	Access plugin settings

Peek's permissions decide which Peek screens someone can use; Craft's entry permissions still decide which drafts:

Diffs need the right to view the draft and its entry.
Adding a draft to a release, and publishing it, need what Craft's editor needs to apply that draft — saving the draft and saving its entry. If the publisher can't apply any one draft, nothing in the release is published.
Scheduled releases publish as the user who scheduled them, with that user's permissions at the moment the release runs. If they can no longer publish a draft, lost the Schedule releases permission, or are no longer active, the release is marked Failed and nothing is applied.

Settings are available in the Craft CP under Peek > Settings, or via config/peek.php:

return [
    'staleDraftDays' => 14,
    'defaultSiteId' => null,
    'enableVisualPreview' => true,
    'maxEntriesPerRelease' => 50,
];
