Stop guessing why your After Effects expressions break or grind your comps to a crawl. ExpressionRx is a native AE panel that scans, diagnoses, profiles, and optimizes every expression in your project — plus a built-in snippet library to write them faster. WHAT IT DOES: • Scanner — scans the active comp, selected layers, or your entire project and flags every expression as Healthy, Warning, or Error, with search + sort by status/layer/comp • Profiler — measures how long each expression takes to evaluate (ms), with configurable iterations and warning/error thresholds, so you can find what's killing playback • Optimizer — analyzes expressions and suggests concrete improvements • Snippets — a searchable library across Animation, Math, Text, Color, 3D, Utility & Time • One-click JSON report of your project's whole expression health Installs as a native panel (Window → Extensions → ExpressionRx). Works in After Effects 2020+ (v17.0+). Includes a one-click .zxp installer.
