Hey Product Hunt — I’m cerebellum, maker of Folio.I kept opening huge IDEs just to read a repo I hadn’t touched in months, or to change two lines in a config. The editor wanted plugins, accounts, and a whole workspace. I just wanted a quiet page.So I built Folio: a native macOS app (Rust + GPUI, no browser chrome) where opening a project feels like opening a document.What it actually does:Read first: syntax highlighting, folding, split views, 60 languages Small edits without ceremony: multi-cursor, project search, careful save The story of the file: git diff vs HEAD, line blame, a terminal when you need it Fully local. No account. No upload. State comes back next time It’s for the in-between moments — an AI-written project, an old folder, a quick look before you decide whether to fire up the heavy tools.Free for macOS 12+ / Apple silicon. Download from folioedit.dev.I’d love feedback on two things:Does “a reader that can also edit” feel useful next to your main IDE? What’s the first thing you’d miss if you used this for a week? I’ll be here all day.
