After Effects: Expression Buddy: is this $15 stack worth it for Films?
If you’ve ever found a perfect wiggle expression on a forum, pasted it into After Effects, and then spent the next twenty minutes hunting for the right slider controls to make it behave, you know the specific pain of expression management. Most motion designers rely on memory or scattered browser tabs to recall these snippets, which turns a quick animation tweak into a slow, repetitive task. Trash Benny built After Effects: Expression Buddy to solve exactly that: it lives inside your timeline as a script UI panel that lets you apply pre-built expressions with their connected controls in seconds. It’s not a course or a tutorial; it’s a utility that removes the friction between your idea and the keyframes.
Quick answer
| Best for | After Effects users who use expressions regularly but hate hunting for code snippets or manually wiring up slider controls. |
| Skip if | You rarely use expressions, prefer writing all your code from scratch, or are looking for a general motion design course rather than a specific tool. |
| Price | $15 |
| Format | Script UI panel + 30 included expressions with controls |
| One-line take | A $15 time-saver that turns expression hunting into a one-click workflow with built-in control management. |
What you’re actually buying
At $15, Expression Buddy is a low-risk bet for anyone who feels their workflow is held back by the “expression gap”—that annoying pause where you know what you want the animation to do, but you don’t have the code memorized. The core value here is the Script UI panel, which acts as a dedicated hub inside After Effects. Instead of copying and pasting text from a cheat sheet, you select a property and choose from a library of expressions that are already wired to work with your project.
The pack includes 30 included expressions, which covers the heavy hitters: wiggle variants, loop effects, and other motion staples that you likely use more than once a week. But the real game-changer is the expression control support. When you apply a wiggle expression, you usually have to manually create a slider control, name it, and link it to the expression. Expression Buddy handles that connection automatically. This means you can tweak the amplitude or speed of your animation without digging through the code, making the tool feel less like a developer’s utility and more like a native part of the interface.

This is particularly useful for the “pick-whipping” problem mentioned in the listing. If you’ve ever tried to adjust a wiggle expression by dragging points on the graph, you know how tedious it is. With the connected controls, you get a clean slider in your layer properties that gives you instant, visual feedback. It’s the kind of small quality-of-life upgrade that doesn’t replace your skills but definitely speeds up your day. (After Effects: Expression Buddy)
Why it’s on our radar
This tool stands out because it addresses a niche pain point with a very specific solution. Many motion design resources focus on teaching you how to write expressions, but Expression Buddy focuses on the application of expressions you already know. It’s a utility for the working designer, not a learning tool. (After Effects: Expression Buddy)
The inclusion of 30 expressions with connected controls is a strong value proposition for the price. You’re not just getting a list of code snippets; you’re getting a managed environment where those snippets are ready to use. For solopreneurs or freelancers who bill by the hour, saving even a few minutes per project on repetitive animation tasks can make the $15 cost pay for itself quickly. It’s a focused, no-nonsense tool that does one job well: making expression application faster and less error-prone. (After Effects: Expression Buddy)
What actually matters
Before you buy, consider how often you actually use expressions. If you’re mostly keyframing position and scale, this might not be a daily driver. But if you use wiggle, loop, or other code-based animations regularly, the time saved on control management alone is significant. (After Effects: Expression Buddy)
Check your After Effects version compatibility. Since this is a script UI panel, it relies on your current AE installation supporting script panels. While most modern versions do, it’s always worth confirming if you’re on an older legacy build.
Also, look at the specific expressions included. While 30 is a solid number, make sure they cover the types of animations you do most. If you specialize in 3D motion or complex physics, you might still need to write custom code. But for 2D motion, UI animations, and general motion graphics, this library is likely to cover 80% of your needs. (After Effects: Expression Buddy)
Mid-check
If you’re tired of copy-pasting code and manually wiring up sliders, this is a straightforward upgrade to your workflow. (After Effects: Expression Buddy)
