  • Yearly price is locked in for the lifetime of the subscription
  • Endorsed publicly by the co-founder of Grafana Labs
  • Strong template library covering portfolio, docs, store and AI-agent apps

Once UI Cons

  • Purchases appear to complete on once-ui.com behind auth rather than via the Lemon Squeezy storefront, so affiliate attribution is unverified
  • Free templates are CC BY-NC and personal-use only — commercial rights require a paid plan
  • Plan cards and the comparison table quote different Pro prices ($193 vs $256)
  • Manual approval, a 7-day cookie, and a commission ceiling that maps to no published plan
  • Uses a limited-spots scarcity line on the pricing page
