The short version

  • Spline is a free 3D design software.
  • Tilt is free; Spline starts at $9/mo.
  • Only Spline lists 3D modeling; only Tilt lists live update.
  • Where Spline falls short: AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks.
  • Prices and features on this page were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Spline

  • AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
  • Limited to simpler designs - not suitable for high-poly, detailed production models
  • Performance degrades with complex scenes containing many objects and materials
  • Limited non-Apple platform coverage compared to cross-platform design tools
  • Tutorials are either too fast for beginners or too basic for advanced users

Tilt

  • Docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform
  • The Tiltfile is Starlark, a Python dialect, so non-trivial setups become real programs that need reviewing and maintaining, and the person who wrote yours becomes a single point of failure
  • Live update only works when the running container can accept synced files and restart the process; compiled languages, distroless images and read-only filesystems often force you back to a full image rebuild, which removes the main benefit
  • It assumes Kubernetes. If your development target is plain Docker Compose or serverless functions, Tilt adds a cluster you did not need and a layer of abstraction with no payoff
  • There is no commercial support contract, no SLA and no paid tier, so when a Kubernetes version upgrade breaks something you are dependent on GitHub issues and a Slack channel rather than a vendor you can escalate to

Answered from the vendors’ own pages

Spline: What is Spline's pricing?

Spline offers a Free plan with watermarked web exports, Starter at $12/month (billed annually) removing watermarks, Professional at $20/month with unlimited projects, and Enterprise with custom pricing. Viewers are unlimited on all plans.

Source
Tilt: Is Tilt free?

Yes, entirely. It is Apache 2.0 open source with no paid tier and no licence fee.

Spline: Can Spline export 3D models to other tools?

Spline's export/import format support is more limited compared to traditional 3D tools like Blender. It focuses on web-first exports and native app code generation.

Source
Tilt: Who owns Tilt now?

Docker, which acquired it in May 2022. It remains open source and the repository is still actively maintained.

Tilt: Do I need a remote cluster?

No. It works against a local cluster such as kind, minikube or Docker Desktop, and also against a shared remote development cluster if your services are too heavy to run locally.

Tilt: How is it different from Skaffold?

Both automate the build-deploy loop. Tilt puts more weight on the live-update path and a multi-service dashboard; Skaffold is more configuration-driven and closer to Google's tooling.
