Mostly Vibes is a software initiative with one goal: to see how far we can get without writing a single line of code by hand. Every project is built entirely through AI-generated code — guided by senior development experience, but never manually written. Just ideas, direction, and vibes.
Current projects lean into retro computing and audio — bringing classic sound chips, forgotten file formats, and vintage music tools back to life on modern platforms. But Mostly Vibes is also a playground for fun ideas and experiments. Expect a growing collection of small tools, creative hacks, and things that simply seemed interesting enough to build. Every project starts from curiosity and ships entirely through AI.
