Affinity Photo Supports Photoshop Plugins
You can get Photoshop Plugins, like Nik Collection to work with Affinity Photo. However, you might need to re-install Nik Collection Plugins and set it up for working Affinity Photo.
Once installed it works flawlessly, with the change that the plugin effect is applied to the active layer instead of new layers, as Photoshop users are used to.
