K4tron Coder
An AI coding agent that lives in your VS Code sidebar. It reads, writes, and
runs code in your workspace — streaming its reasoning, showing every file
change as a reviewable diff, and asking for your approval before anything
sensitive.
Website: k4tron.com · Your account:

Quick start
- Install the extension and open the K4tron panel (activity bar icon, or
Ctrl+Alt+K / Cmd+Alt+K).
- Connect your machine to your k4tron account — grab a device code at
app.k4tron.com/connect and paste it in.
- Type what you want done. The agent works on the open workspace.
No API keys, no settings to configure — usage is billed through your k4tron
account.
What it does
- Reads and edits your code — every change is presented as a diff you can
review before it lands, right in the feed.
- Runs commands — terminal actions go through an approval gate; approve
one, or turn on auto-approve for the session.
- Works in two modes —
free for a single focused agent, swarm for a
supervisor that delegates to parallel sub-agents on bigger tasks.
- Presets, not model pickers — choose a tier (
lite · basic ·
standard · premium) and k4tron takes care of the rest.
- Persistent sessions — close VS Code, come back tomorrow, and resume
exactly where you left off, full context included. Sessions are per
workspace, with live cost and context tracking in the panel.
- Workspace instructions — drop
.agent/*.md files in your project to
teach the agent your conventions.
- MCP support — connect Model Context Protocol servers to extend the
agent with your own tools.
Your data stays put: sessions, preferences, and auth live in your user data
directory (~/.k4tron on Linux/macOS, %LOCALAPPDATA%\k4tron on Windows),
never inside your project.
The same agent, everywhere
Prefer the terminal? The identical engine ships as a CLI:
npx k4tron
Sessions are shared between the extension and the CLI — start in one, resume
in the other.
