Spline has introduced a long‑requested timeline for animation, enabling creators to precisely control motion with clips, keyframes, and editable curves.
In a brief demo posted on X, the company highlighted how users can now “easily control timing by adjusting clips or make detailed adjustments with keyframes or curves,” showcasing a 23‑second preview of the workflow.

What’s new
The new timeline appears to center around three pillars:
Clips: Segment and rearrange animation sequences, making timing changes feel more like video editing in a nonlinear editor.
Keyframes: Set exact values at points in time for properties (e.g., position, rotation, scale), allowing for complex motion choreography.
Curves: Fine‑tune easing and interpolation on a per‑property basis, giving artists granular control over acceleration, deceleration, and expressive motion dynamics.
In a reply to a creator asking, “Wow since when we have timeline in Spline?” (Ďiv / @DivyanshDesign ↗), the Spline team confirmed the feature is “Brand new ♥️ Shipped two days ago.” That timing suggests the rollout began around September 18.
Why it matters
For many 3D and motion designers, the lack of a robust timeline has been the single biggest gap in Spline’s pipeline. A timeline unlocks:
Professional‑grade motion control: Keyframes and curves are foundational for animators used to tools like After Effects, Blender, and Cinema 4D.
Faster iteration: Clips make it simpler to re‑time scenes without rebuilding animations.
Expressive polish: Curve editing is essential for natural‑feeling motion and nuanced product interactions.
The announcement drew immediate attention from designers who’ve been waiting for deeper animation tooling in Spline.
