A real terminal
Every tab runs its own shell through node-pty, and switching tabs never kills it. Right-click for copy, paste and clear; multi-line pastes ask first.

The terminal that
feels alive.
Radon puts a real terminal, a quick-lookup browser and an AI companion in one calm window, so you can run it, read the docs and ask for help without switching apps.

What's inside
Everything for the quick loop. Nothing to babysit.
Built in three weeks, polished since. Radon does a few things and tries to do them well.
A browser for quick lookups
Search docs, check references, read APIs. Each tab keeps its own history and scroll position. A utility, not a Chrome replacement.
Indu, your AI agent
Open a tab and ask about an error or a command. Chats are saved on your computer with a searchable sidebar, and answers come with highlighted code.
One live view at a time
Only the tab you're looking at is active, which keeps memory use low while your shells keep running in the background.
Light and dark
A calm surface with a single glowing accent. Keyboard focus rings throughout, and animations stand down if your system asks for less motion.

Privacy
Indu only knows what you tell it.
Radon is a tool for work, so it keeps its AI on a short leash.
- Messages onlyIndu sees the messages you send it. It cannot see your terminal, your tabs or your browsing.
- Chats stay on your machineThey're stored in Radon's app data folder. Deleting a chat removes its file.

Get Radon
Releases are published on Codeberg. This page reads the latest one, so the links below are always current.
Heads up: Radon is not code-signed yet. Windows SmartScreen may warn the first time you open the installer: choose More info then Run anyway.
On Linux, mark the AppImage as executable first: chmod +x Radon-*.AppImage.
Build from source
Prefer to compile it yourself?
You need Git and Node 22 or newer. Indu needs a free Google API key in a .env file; the terminal and browser work without one.
# get the code
git clone https://codeberg.org/pfmcodes/radon.git
cd radon
npm install
# optional: enable Indu
echo "GOOGLE_KEY=your-key" > .env
# run it
npm start
