Where each one falls short

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

Blacksmith

  • Per-minute pricing model requires estimating usage to predict costs
  • macOS M4 pricing ($0.08/min) is significantly higher than GitHub Actions
  • Docker layer caching and sticky disks are paid add-ons at $0.50/GB/mo
  • Static IP add-on costs $100/IP/mo

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

Source
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.

Blacksmith: Can I use Docker layer caching with Blacksmith?

Yes, Docker layer caching is available as an add-on at $0.50/GB/mo. Managed Docker layer persistence is included with the base service.

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.

Blacksmith: What is the SLA for Enterprise plans?

Enterprise Blacksmith plans include a 99.9% SLA guarantee along with 24/7 priority support, dedicated Slack channels, white-glove onboarding, and CI optimization support.

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.
