Why we like it

Keyless earns its place in the aescripts library by handling easings and controls automatically for keyframe-free animation, with recent additions like path property support and a linear easing type.

What is Keyless?

Keyless is an After Effects script from YB Motion that lets you animate any property without keyframes. It applies Penner easings and the right controls automatically, so you can build motion without setting keyframes by hand. This suits MOGRT creation and anyone who has moved past the linear() function.

Version 1.1.0 adds path property support, letting you apply Keyless on path properties using key keyframes. It also introduces a linear easing type, added on popular user request, and makes the overshoot control more intuitive with a default value of 1.70158.

Keyless runs in After Effects 2026, 2025, 2024, 2023, 2022, 2021, 2020, and CC 2019. The 1.1.0 update arrived on October 29, 2025. It is listed here as free, and a demo video is available on the developer's page.

Who is Keyless best for?

Keyless is best for mOGRT creation and After Effects users who want to animate without keyframes and have moved past the linear() function.

How much does Keyless cost?

Keyless is completely free to download and use.

Frequently asked questions

Which After Effects versions does Keyless support?

Keyless supports a broad range of After Effects releases, running in After Effects 2026, 2025, 2024, 2023, 2022, 2021, 2020, and CC 2019. That span covers recent Creative Cloud builds as well as older versions going back to CC 2019, so most current installations should be able to run it. Version 1.1.0, released on October 29, 2025, is the latest build. For the definitive, up-to-date compatibility list, check the developer's page before installing, since supported versions can change with new releases.

Is Keyless free to download?

Keyless is listed here as free, so you can add it to your toolkit without a purchase. Licensing terms can change over time, and free tools are sometimes updated to paid versions or add optional paid tiers, so it is worth confirming the current arrangement on the developer's page before you rely on it. That page will also carry the latest version, which at the time of writing is 1.1.0, released on October 29, 2025.

What did the Keyless 1.1.0 update add?

Keyless version 1.1.0, released on October 29, 2025, adds path property support, letting you apply the effect on path properties using key keyframes. It also introduces a linear easing type, which was added on popular user request, and makes the overshoot control more intuitive by setting a default value of 1.70158. The initial release came out on March 18, 2025. For the full history and any tutorials on the new path property workflow, refer to the developer's page.

Does Keyless work with path properties?

Keyless works with path properties as of version 1.1.0, which added the ability to apply it on path properties using key keyframes. This extends the keyframe-free approach beyond standard properties. A tutorial for this workflow was noted as coming soon at the time of the 1.1.0 release, so more guidance may appear on the developer's page. If path animation is your main use, confirm the current details there, since the feature was introduced in the October 29, 2025 update.
