My personal, customized build of termio: a terminal-first agentic development environment for macOS. fyolo is a fork of termio-sh/termio, tuned to how I work and extended with my own custom connectors.
It is not a product and is not for sale. It's open source because termio is.
brew install --cask fl0wo/tap/fyoloUpdate with brew upgrade --cask fyolo. Needs macOS 14 or later.
- Renamed throughout to fyolo, so it installs and runs beside termio without sharing state, sockets, or settings.
- Dark appearance and the bundled FLO theme (IR Black on pure black) are the defaults.
- The sidebar takes the theme's background, so it sits flush with the terminal.
- Custom connectors.
For what the app does and how it works, see termio's README and the docs.
Requires Xcode 26, Rust, and Zig 0.16 (brew install zig@0.16).
