About Thicc Stroke

Thicc Stroke is a free, fully‑featured plugin that adds variable‑width strokes to both masks and shapes in After Effects. Width is controlled via unlimited points using the feather vertex tool, and users can select Butt or Round caps. Gradient options include 2‑, 3‑, and 4‑color loops, and version 1.2 adds a custom parameter for gradients with more than four colors. Trim path controls are built in, allowing width, color, or both to be driven by trim paths. The plugin supports a broad range of After Effects releases—from CS6 through the 2026 version—and includes native Apple Silicon (M1+) support. A demo video is provided on the developer’s page.
