Splice

117 mentions across 6 sources · 35% positive — critical (weighted across 6 sources)

Hacker News, YouTube, Product Hunt, App Store, Stack Overflow, Lemmy

What users praise

  • • Royalty-free, commercially cleared catalog spanning 90+ genres from hip hop and trap to house and EDM.
  • • Download individual samples instead of buying whole packs, so you only pay for what you use.
  • • Keep every sound you download even after you cancel — genuinely user-friendly licensing.
  • • Unused credits roll over month to month, softening the pressure of a monthly cap.

What frustrates them

  • • Genuine user feedback is thin and old — most reviews predate the current credits-and-plugin model.
  • • Launch-era UX complaint: one reviewer paid, got a 'useless app', and downloaded no samples.
  • • Early Ableton-only integration frustrated producers on other DAWs before the recent beta.
  • • Samples cost one credit but MIDI and presets cost up to three — fast to burn through on the base tier.
