Physarum earns its place in the aescripts library as a native, easy-to-use plugin focused on organic growth, with compatibility stretching from CC 2017 to After Effects 2026 and support for Apple's M1 chip.
Physarum is a native After Effects plugin from Zaebects that simulates organic growth. It relies on an organic algorithm and can interact with composition layers, producing a countless number of results. It is presented as an easy-to-use tool for motion designers.
The plugin covers a broad span of After Effects releases, from After Effects 2026 back through CC 2017, so it fits both current and older installations. On the Mac side, a version 1.2 update added compatibility with Apple's M1 chip, and an earlier release notarized the plugin for macOS Catalina.
Physarum also ships with sample projects, originally added for After Effects 2020 and 2018 and later updated to match the plugin version. Sitting at rank 471 in the aescripts library, it is a native effect aimed at motion designers looking to generate organic forms directly inside their compositions.
Physarum is best for motion designers who want to generate organic growth effects directly inside After Effects compositions.
Physarum is completely free to download and use.
Physarum lists compatibility with a wide range of After Effects versions, spanning After Effects 2026, 2025, 2024, 2023, 2022, 2021 and 2020, along with the older CC 2019, CC 2018 and CC 2017 releases. That range covers both current and legacy installations, so most editors running a recent or several-year-old build should be able to use it. If you are unsure whether your specific setup qualifies, check the developer's page for the latest confirmed version details before installing.
Physarum became compatible with Apple's M1 chip in its version 1.2 update, released in April 2022, so it runs on Apple silicon Macs from that release onward. An earlier update also notarized the plugin for compatibility with macOS Catalina. If you are on Apple silicon or a recent macOS version, those changes indicate support, though it is worth confirming your exact hardware and operating system against the developer's page before relying on it for a project.
Physarum is listed as free here, so you can add it to your setup without a purchase. Licensing terms on distribution platforms can change over time, so it is a good idea to confirm the current cost and any usage conditions on the developer's page before downloading. As a native After Effects plugin from Zaebects, it installs into After Effects and is aimed at motion designers who want to generate organic growth effects directly in their compositions.
Physarum ships with sample projects, which were first added for After Effects 2020 and After Effects 2018 in the original release and later updated to match the current plugin version. These give you a starting point for working with the plugin rather than building a composition from scratch. If you want to see exactly which sample files are bundled with the release you download, the developer's page is the place to check.
