The short version

  • Only LottieFiles has a free tier, so it costs nothing to try first.
  • Each has a real cost: LottieFiles lottie only renders the After Effects features the player libraries implement, so expressions, most effects, layer styles and merge paths behave inconsistently or fail outright, and you must test every animation on web, iOS and Android before shipping.; Principle macOS only with no Windows or Linux editor available
  • They diverge on capability: LottieFiles covers Lottie Creator, Principle covers Timeline-based animation.
  • Prices and features above 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.

LottieFiles

  • Lottie only renders the After Effects features the player libraries implement, so expressions, most effects, layer styles and merge paths behave inconsistently or fail outright, and you must test every animation on web, iOS and Android before shipping.
  • Runtime cost scales with path and keyframe count, so a detailed illustration animated at 60fps can consume more CPU on a low-end Android handset than the video it was meant to replace.
  • The free plan caps private files and collaborators, so once a team standardises on the platform for handoff the seat count grows with reviewers and stakeholders, not just with animators.
  • Using the hosted CDN puts a third-party request in your page or app load path; self-hosting removes that dependency but also removes the versioning and analytics that justified the subscription.
  • The browser editor still does not replace After Effects for character work or complex effects, so most studios keep an Adobe subscription running alongside it and pay for both.

Principle

  • macOS only with no Windows or Linux editor available
  • No vector morphing capability for complex shape transformations
  • Limited asset creation tools; cannot create vectors or shapes directly within Principle
  • Sketch import flattens certain properties including paths, fills, borders, masks, blur effects, and text layers
  • Limited variable support, logical loops, and data input capabilities compared to tools like ProtoPie or Origami

Answered from the vendors’ own pages

LottieFiles: Do I need After Effects to produce Lottie files?

No. Lottie Creator and the Figma plugin both output Lottie directly. Character animation and anything using complex effects still goes through After Effects.

Principle: Does Principle run on Windows or Linux?

No. Principle is macOS only and runs on Intel and Apple Silicon Macs. There is no Windows or Linux editor available; however, prototypes can be shared and viewed on any platform via web link.

Source
LottieFiles: Is the format proprietary?

No. The Lottie JSON schema and the player libraries are open source under permissive licences and dotLottie is an open container, so files keep working after you stop paying.

Principle: What is the cost of Principle?

Principle costs $129 for a one-time purchase with 1 year of upgrades included. After 1 year, upgrade licenses cost $99/year. A 14-day free trial is available with all features included.

Source
LottieFiles: Why does the same file look different on Android?

Each platform ships its own renderer with its own level of feature support. Test the exact file on every target rather than trusting the After Effects preview.

Principle: Can I import designs from Figma or Sketch into Principle?

Yes. Principle supports importing designs from Figma and Sketch with intelligent merging of re-imported files. Some Sketch properties such as paths, fills, borders, blur effects, masks, and text layers are flattened upon import.

Source
Principle: How do I share Principle prototypes with others?

Prototypes can be shared via web link with one click (File > Export > Share to Web). Recipients can view and interact with prototypes in any browser on any platform: Windows, macOS, Linux, Android, or iOS. No installation required.

Source
Principle: Can I create vector shapes and morphing animations in Principle?

Principle does not support vector morphing, where vector objects transform into other vector shapes. It also has limited asset creation capabilities and editing is restricted to basic operations like scale and rotate.
