PricingPay per token — model-dependentFree + $5-$30/moFree + $12-$48/moPay per second of compute
Best forDevelopers experimenting across models. Apps that want fallback logic.Designers shipping marketing sites without engineers.Designers, brand teams, anyone needing vector output or tight style control.Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • AI generates sections + copy + layouts
  • Designer-first publishing (not just templates)
  • Great animations
  • Exports SVG vectors — rare in AI image gen
  • Strong style control + consistency
  • Brand kit for consistent outputs
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
Weaknesses
  • Slight markup over direct API
  • Some provider features not exposed
  • Less flexible than raw code
  • Pricing per-site adds up
  • Less hyped than Midjourney
  • Learning curve for non-designers
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for designer-led sites. S-tier if animations matter.S-tier for designers. The only one that takes vectors seriously.S-tier for open-source model APIs. The default in this space.
