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.
