Pros and cons

Melyx AI

Pros

  • Simple studio with text, custom-lyrics and instrumental modes
  • Two variations per 10-credit request
  • Free credits to try before paying
  • Failed tasks are refunded automatically
  • Monthly list prices and add-on pack prices are published

Cons

  • The underlying music model is not named
  • The operating company is not publicly disclosed; the footer and terms name only "Melyx AI"
  • The pricing page opens on the Yearly tab with a "Flash Sale 50%" label and "Billed Annually" shown next to the monthly rate, which makes the monthly cost unclear
  • Pricing FAQ (3 days) and refund policy (14 days) disagree on the refund window
  • Subscription credits do not roll over, and add-on packs are for subscribers only
  • Extension, stems, music video and remix features are only announced; no API or mobile app

Runway

Pros

  • Combines video, image and audio generation and editing in one workspace
  • Offers Runway's own Gen-4.5 plus third-party models such as Seedance 2.0
  • Creative Agent builds videos from a conversation
  • Runway Dev API with Node and Python SDKs
  • Free plan with 125 credits that do not expire
  • Native iOS and Android apps

Cons

  • Credit-based pricing: a 5-second Gen-4.5 clip costs 60 credits, so the 625 credits on Standard cover about 10 such clips
  • Standard and Pro credits do not roll over at the end of the month
  • Some App Store reviewers complain about the cost of failed or unusable generations
  • 4K upscaling is unlimited only on Pro and Max
