SFXMint

SFXMint is a copyright-clean sound effects library. Every sound here is created by open-source AI models or procedural synthesis — nothing is scraped, re-hosted, or copied from other sound libraries. Because we generate everything ourselves, we can dedicate the entire catalog to the public domain under CC0 1.0.

That means you can use any sound in commercial games, videos, podcasts, apps, and products with no attribution, sign-up, or license fees. Hotlinking the audio files directly into your own project is allowed and encouraged — URLs are permanent and immutable.

Downloading from this website has a daily allowance; it limits our download service, not the license. For developers and AI agents, the whole library is also available through a JSON API and MCP server, free to try with no key: 20 lookups and 5 downloads a day. See the API docs for limits, endpoints, and examples. Sounds are AI-generated — Powered by Stability AI.

We automatically verify each file’s format, duration, and checksum, and each sound’s page lists its measurements. Synth-style sounds are additionally produced with our in-browser procedural generators. SFXMint no longer makes sounds to order.

The library stays free to search and hear, and new sounds join it from what people search for and don’t find. SFXMint is built and maintained by flreey, an independent developer. The API, the MCP server, and the integration guides are developed in the open at github.com/sfxmint/sfxmint-mcp. Choosing and reviewing sounds.

Catalog titles and prompts describe the intended event. File checks, acoustic measurements, and listening judgments answer different questions. Our sound-selection guide compares concrete examples, explains the measurements, and gives you a checklist for trying them in a finished scene. License.

An MCP server for Claude Code, Cursor, and Codex, a JSON API, and npx sfxmint. Facts an agent can use: Results carry each file’s length, measured attack, SHA-256, and addresses that never change. The library is organized into 23 categories, including UI sound effects, 8-bit and retro game sound effects, transition and whoosh, impact and hit, nature and ambiance, footsteps, doors, mechanical, magic and sci-fi, horror and suspense, success and error, vehicles and household sounds. There are 19 ready-made sound sets, including ui-crisp, ui-soft, retro-game, chat-app, saas-app, checkout, platformer, horror-game, fantasy-rpg, video-editing, and ai-coding-tool. Each set page has a role-to-hotlink URL map.
