CC0 sound effects for apps and games, including UI cues. AI-generated or procedurally synthesized; individual library downloads need no account or API key.
Why we recommend it
I run SFXMint. It lets product designers preview interface sounds in an interactive app demo, then download individual WAV/MP3 cues or use the JSON API and MCP integration. The free library is useful for prototyping clicks, toggles, notifications and success/error feedback. ZIP downloads require a free account; custom generation is a separate paid feature. The audio is AI-generated or synthesized, and should be auditioned in context; not every file has been listened to by a person. This submission was prepared with AI assistance.

Keep in mind
- AI-generated and procedurally synthesized audio may lack the nuance of recorded foley for detailed sound design.
- Individual library downloads require no account, but there is no API key mentioned for programmatic access.
- Freemium pricing details are not specified, so limits on the free tier are unclear.
