Particle Pro, developed by LetsMotion, is an After Effects plugin for creating particle effects. It is powered by Stardust, which is required and must be purchased separately. The effects are built from presets organized into categories, giving you a preset-driven approach to particle work inside After Effects.
The plugin runs on version 1.5.0, last updated in February 2024. It is compatible with After Effects 2025, 2024, 2023, 2022, 2021, 2020, and CC 2019. Across its release history, the library has expanded: a Shockwaves category arrived in an early update, and a later update added a new category with 40 presets, alongside a framework update and bug fixes.
Particle Pro is listed in the aescripts library, and a demo video is available for a closer look. Because it depends on Stardust, that plugin needs to be in place before Particle Pro's presets can be used.
