Browse & install

Pressline ships with a built-in marketplace client. Open Rozšíření → Marketplace to browse, search and install plugins from marketplace.pressline.app.

What it does

• Browses categories and search results
• Verifies sha256 of every download against the registry's X-Package-Sha256 header
• Atomic install — extract to a staging folder, swap on success, keep a backup on failure
• Runs the plugin's migrations on activation
• Reports anonymous install pings (toggle in settings)
• Caches update detection for one hour
