Install

Every plugin in the suite is free to install. Once a plugin is live on the Figma Community, install it from its Community page with one click. The steps below are for loading a plugin from its source folder, which needs the Figma desktop app.

Steps

Open the Figma desktop app (macOS or Windows).
Open any design file.
In the menu, choose Plugins → Development → Import plugin from manifest…
Select the manifest.json inside the plugin's folder, for example pixel-squeeze/manifest.json.
Run it any time from Plugins → Development.

Repeat for each plugin you want. There is no build step and there are no dependencies: each plugin is a manifest, a code.js, and a ui.html.

After editing a plugin's files, just run it again. Figma re-reads the files on every launch, so there is nothing to rebuild or reload.

Updating

Community installs update automatically. For a source-folder install, replace the folder with the new version; Figma reads the files at launch, so the next run is the new version. Saved presets and an activated Pro license live in Figma's client storage and survive updates.
