Two days ago I posted five new tools. Yesterday two more. That puts 27 apps in the Fe₂O₃ suite, and I am starting to lose sight of all the wonderful apps. So the suite got a front door, simply called fe2o3.
The grid
Every app as a card: its logo, what it is, one line on why. Arrow keys move. Enter runs it in the same terminal, and when you quit you are back on the grid. ? pops up that app’s own help, w opens its repo, / filters.
Six groups, each with its own tint; daily drivers, desk, science, media, play, system. Plus the retired shelf, where rush and crush now sit.
It installs, too
Grab this one binary and it fetches the rest.
i downloads the app under the cursor from its latest release. I downloads every missing one on screen. Solid frame and a green tick means you have it. Dashed frame and an amber down-arrow means it’s one keypress away.
You can take the launcher, walk the grid, and pick up only what you fancy.
Binaries land in ~/bin, or ~/.local/bin if you have no ~/bin.
Summary
Built with Claude in an evening. One static binary, logos baked in. It does one blocking read on stdin and nothing else while it waits, like the rest of the suite.
curl -L "https://github.com/isene/fe2o3/releases/latest/download/fe2o3-linux-x86_64" \
-o ~/bin/fe2o3 && chmod +x ~/bin/fe2o3
fe2o3
Then press I for all of it, or i for the one you want.
Public Domain, like everything I make.
