What is suprow?

suprow is a lightweight desktop browser for web apps.
It focuses on fast startup, minimal UI and keyboard‑centric workflows, so you can keep separate, focused spaces for different kinds of work.

Key ideas

• Lightweight browser
  Not a bloated, general‑purpose browser, but a focused shell‑style browser for web apps. Fast startup, minimal chrome, maximum focus.

• Spaces instead of tabs
  Organise your tools into spaces like work, deep‑focus, playground.
  Each space can have its own apps, settings and windows.

• Keyboard‑centric UI
  Terminal‑like vibes with a command palette and clear text UI.
  suprow feels more like a window manager for web apps than a classic browser.

Screenshots & assets

The assets/ directory contains the public marketing images used on the website and in this README.

CLI concept (illustrative)

Some screenshots show a terminal prompt like:

suprow@desktop: ~
λ suprow --space work --app mail
↳ launching focused mail space…
λ suprow --space side --app github --pip
↳ picture‑in‑picture debug browser enabled

This is illustrative only.
suprow is a desktop app today, not a real CLI tool (yet).
If a future CLI becomes available, it will be documented here.
