A couple of years ago, my girlfriend and I started Preloved, a secondhand fashion marketplace in Indonesia.
I built the entire thing solo, back when AI wasn't writing your code. Turns out building a marketplace is a lot more than just letting people buy and sell stuff
I write a lot of notes, all in one folder of markdown files. Apple Notes felt too limited, and Obsidian felt sluggish and way more than I needed. I just wanted a nice window on top of my folder, so I built one. It's native, fast, free and open source, and it uses the AI you already have installed (Claude Code, Codex, Cursor) instead of charging you again. Delete it tomorrow and your notes are still right where you left them.
A fast, native PostgreSQL client for macOS. Its AI assistant runs on the Claude Code, Codex or Cursor account you already pay for, sees your real schema, and can only read: any change it suggests waits for you to dry-run and apply. Free and open source.
