What is SFXMint?
SFXMint helps designers and developers find or create short sound effects for apps, interfaces, games and video. Search, preview and download individual CC0 library files for free without an account; ZIP downloads require a free account. The library includes AI-generated and procedurally synthesized audio.
The public-library API and remote MCP work without an API key. Studio offers limited free generation plus optional paid passes starting at $3.90 for 24 hours or $9.90 for 30 days, without automatic renewal. Generation through the API has separate authentication and paid-access requirements. Submitted by the maker.

Make a list of all the subreddits where my ICP is hanging out — at least 15 subreddits. Any subreddit greater than 5,000 members is okay. Smaller subreddits are sometimes better — niche audiences, simpler rules, mods are more forgiving. Post on one subreddit per day, tweak the copy, repeat. Never post on all subreddits in one day — people see the overlap.
Post one Reddit demo per day across 15+ niche subs with UTMs on every link
Aayush built a 15-subreddit list (5K+ members each, favoring smaller niches), then posted one video demo per day to a single sub, tweaking copy between posts and tagging every link with UTMs by feature, date, and subreddit. This avoided spam-pattern detection from overlapping audiences while giving him clean attribution on what actually converted.
I start by fixing a hard deadline — if I don't have any constraint in time then there will always be something to add.
Constraint-Based Deadlines Force You to Ship Only What Matters
Nico sets a firm shipping deadline before writing a line of code, then strips every feature to only what's essential. The pressure collapses scope and kills perfectionism before it starts.
There's a play for whatever you're stuck on.
