Flow alternatives for easing in After Effects

What does Flow do in After Effects, and who makes it?

Flow is an easing tool for After Effects, built as a graph editor and a curve library. It is a collaboration between Zack Lovatt and renderTom, listed on aescripts.

It has two main parts, the Graph Editor and the Library. The Graph Editor is all about easing: the maker pitches it as a modern, snappier, normalized environment that replaces After Effects' internal graph editor. The Library holds curves. Flow ships with 25 commonly used animation curves, and you can save any curve as a preset and build your own easing libraries.

The product page also lists:

• sharing your library
• applying curves as expressions
• copying or pasting a curve as cubic bezier values
• exporting your library to KBar, so you can skip Flow's own interface

Version 1.5 added multi-library support, responsive overshoot and undershoot of graph values, a dynamic controls location and the KBar export. The changelog notes two small controls. Shift + drag in the graph editor snaps to grid cells (added in 1.5.0), and Shift + Ctrl applies inverted easing (1.4.0b, keys as the changelog writes them).

On versions, the compatibility list shows After Effects 2026, 2025, 2024, 2023, 2022, 2021 and 2020. Version 1.5.1 raised the minimum to After Effects 17.5 (CC 2020). The newest entry in the version history is 1.5.2, dated 8 November 2023, which fixed KBar buttons not working on macOS. The page we read doesn't list Windows and macOS requirements as such.

Why do people look for a Flow alternative?

Usually because they want something Flow isn't built around: ready curves with no drawing, easing that stays live as keyframes move, or easing inside a toolkit they already open every day. These are the trade-offs the product pages point to; we haven't surveyed anyone.

• You don't want to draw curves. Flow's strength is its graph editor. If you mostly reach for the same handful of eases, a set of ready curves and one Apply press may cover it.
• You want the easing to follow your keyframes. Flow can apply curves as expressions, but an expression-first tool such as Ease and Wizz is built around that from the start.
• You want fewer panels. If you already work inside a larger panel, its easing tab may cover the same ground without another window to dock.
• You want a recent release. Flow's last listed release is 1.5.2, from November 2023. Its compatibility list still names After Effects 2026, so that alone isn't a reason to leave.

If you came here from a script thread, our summary of what Reddit threads say about After Effects scripts covers the wider script picture.

How do Flow and its alternatives compare? (checked 3 November 2026)

Each tool is shown as its own page showed it on 3 November 2026. "Not published" means the page we read didn't state it, so check the maker's page before you buy.

Is Ease and Wizz a good alternative to Flow?

Yes, if you want easing that stays live. Ease and Wizz is a set of expressions that give After Effects more ways to interpolate between values, applied from an After Effects-style palette you can dock.

The curves are Robert Penner's easing equations, adapted by the author to run as After Effects expressions. That has one practical payoff: the keyframes stay editable. Drag an object in the comp viewer or slide a keyframe in the timeline, and the easing updates straight away.

Other details from its page:

• It works on animated properties of any kind, not only motion.
• The Curvaceous option applies easing expressions to curved motion paths and to mask or shape layer paths.
• Since 2.6.0, you can pick End only under Keys. It eases the last two keyframes and leaves the others with their original easing.

The caveats sit on the same page. The current version is 2.6.1, dated 10 November 2021, and the compatibility list runs from CS4 to After Effects 2024. Support for 2025 or later isn't listed, and the page we read gave no price, platform list or licence. Test it in your own version before you build a project on it.

Best for: motion designers who retime constantly and want the ease to follow the keys. Not for: anyone who wants to shape a custom curve by hand, which is Flow's job. For a hand-written overshoot, our inertial bounce expression guide covers the plain-expression route.

Where mouzeclick fits (we make it)

mouzeclick fits if you want ready curves and one-click eases rather than a curve you draw. It handles easing in two places: the Easing lab inside the After Effects workspace, which is Windows only, and mouzerun, an extension that runs on Windows and Mac.

The Easing lab (Windows only)

The Easing lab is one of the three quick workspaces in the mouzeclick workspace for After Effects, beside Motion lab and Toolbox. Open it from Window › Extensions › mouzeclick workspace. It has:

• six curve types: Bezier, Spline, Elastic, Bounce, Wave and Steps
• 44 ready curves: 21 under Def and 23 under Base, plus your own under Mine
• Read, Apply and Auto buttons
• copy a curve as an expression, or export curves as an .mzgraph file

Our guide to the 44 After Effects easing presets goes through them one by one. The workspace holds 800+ tools, presets and templates on Windows, and the all-in-one After Effects extension page covers its other sections. The workspaces are part of mouzeclick on Windows. The Mac app does not include them.

The Premiere Pro workspace has its own Easing lab, also Windows only. It is Graph Editor 2.0, with the same six curve types and 44 curves, and the curve is baked into the keyframes of the properties you tick. See easing keyframes in Premiere Pro.

mouzerun ease buttons (Windows and Mac)

mouzerun gives you your own one-click buttons in After Effects. A button can be one of five kinds: a script, an expression, an animation preset, a menu command or a keyframe ease. It comes with six starter buttons, and you can export and import your set. The mouzerun feature list shows all 31 items.

It is one of the 15 After Effects extensions on the extensions page. Press Install After Effects bridge on the app's Tool wheel page, restart After Effects and open it from Window › Extensions. On a Mac, follow the four-step Mac install first. Apple hasn't notarized the app yet, so macOS asks you to allow it the first time it opens.

What it doesn't do

We haven't shown a free-drawing graph editor for After Effects here, a KBar export or Flow's multi-library setup. If those are why you use Flow, keep Flow. mouzeclick also publishes no minimum After Effects version, so check yours with the 3-day trial.

It is one plan: $25 a month, $249 a year, or $499 once for one of the first 100 lifetime keys. The pricing section has the details. The trial is 3 days with no card, and every After Effects tool works fully during it.

Does Motion Studio by Mt. Mograph replace Flow for easing?

We can't tell from its own page. Mt. Mograph's pricing page describes Motion Studio as a tool for After Effects and Illustrator 2021, 2022, 2023, 2024 or later. The parts we checked don't describe its easing tools, so we won't guess how they compare with Flow's graph editor.

What the page does give is a clear trial: download Motion Studio from the Downloads page and use it free for 7 days, with no credit card and full access to all features. That is enough time to ease a few real shots and decide. The page names Motion Studio; we found no product called Motion Tools Pro on it, in case that's the name you searched.

Best for: anyone already considering Motion Studio who will judge its easing on their own shots during the 7-day trial. Our Motion Studio alternative comparison sets the wider toolkit side by side with mouzeclick.

Can you get good easing in After Effects without a plugin?

Yes. After Effects has its own graph editor. Flow's page pitches replacing that internal editor with a snappier, normalized one, so the native editor is the baseline every tool here is measured against.

Start with our Easy Ease guide, with its shortcuts and fixes. If the native editor already gives you the curves you want, a plugin's main gain is reuse. Flow saves curves as presets in libraries. The Easing lab keeps 44 ready curves, plus your own under Mine, on Windows. A mouzerun button applies a keyframe ease in one click.

Expressions are the other route with nothing to install. The inertial bounce expression guide linked above writes overshoot by hand. Ease and Wizz shows how far the expression approach can go: Penner's equations, applied from a dockable palette.

Where Flow is still the better pick

Flow is the better pick when the curve itself is the work. If you shape eases by hand and reuse them across projects, nothing else on this page matches what its page lists.

• Drawing custom curves. Its graph editor is a normalized environment built around easing, with Shift + drag snapping to grid cells. The Easing lab gives you ready curves and curve types; Ease and Wizz gives you equations.
• Overshoot and undershoot. Version 1.5 added responsive overshoot and undershoot of graph values.
• Libraries. Several libraries, shareable, with your own curves saved as presets on top of the 25 built in.
• Handing curves to other tools. Copy and paste cubic bezier values, apply curves as expressions, and export the library to KBar. If KBar is your launcher, our KBar alternative page explains how a mouse wheel differs from a toolbar.
• Inverted easing. The changelog lists Shift + Ctrl for the inverted curve.
• Current host versions. Its compatibility list names After Effects 2026; Ease and Wizz's stops at 2024.

If two or more of those matter to you, keep Flow. Nothing stops you running it beside any other tool here.

Which easing plugin should you pick for After Effects?

Pick by how you ease, not by the longest feature list.

1. You draw and save your own curves: Flow. A trial is listed on its page.
2. You retime constantly and want the ease to follow: Ease and Wizz, after testing it in your version, since its list ends at 2024.
3. You want 44 ready curves inside a bigger workspace, on Windows: mouzeclick's Easing lab.
4. You want one-click eases on Windows or Mac: mouzerun buttons, each able to hold a keyframe ease.
5. You are weighing Motion Studio and will judge its easing yourself: its 7-day trial.
6. You ease a few shots a week: the built-in graph editor may be enough.

Whatever you pick, test it on a real comp with your own keyframes during a trial. Easing is about feel, and ten minutes on your own shot tells you more than any table. For tools beyond easing, see our best After Effects plugins for 2027.

Can you trigger easing from a mouse button?

Yes, for anything your easing tool or After Effects puts on a keyboard shortcut. The mouzeclick mouse app runs on Windows and Mac and puts any key combination or macro on a mouse button, per app. A side button can send an ease shortcut in After Effects and do something else in your browser.

• It works with any mouse your computer sees, using up to five standard buttons plus scroll and tilt, with no driver.
• Each button has eleven slots: tap, hold, move in four directions, a chord with another button, or hold and scroll.
• The Options wheel (F8) holds 48 favourites per app on three rings of 12, 16 and 20. It can hold keys, macros and your own shortcuts.
• The built-in library has 309 shortcuts on Windows, 44 of them for After Effects.

The macro recorder handles keys, clicks, waits and typed text, so a multi-step routine can sit on one gesture. Inside After Effects there is also the Tool wheel, opened with F10 or a held right button, with 114 tools in 13 groups on Windows and Mac. The After Effects radial menu guide shows how it works.
