Your coding agent, wherever you work.
k4tron reads, edits and runs code in your project — it doesn't just suggest. No API key, no setup: you pick the tier, the platform handles the models, and usage shows up in credits, in real time.
It doesn't suggest. It executes.
k4tron acts on your real project: it reads files, edits with a diff, runs commands, starts dev servers and commits — and you watch every step, diff by diff, in your editor or terminal. Approve each action, or turn on auto-approve.
One agent, two surfaces
The extension and the CLI are the same k4tron — same account, same tiers, same skills.
VS Code extension
The agent inside your editor: conversation feed, review-style diffs on every edit, one-click approvals.
CLI in the terminal
The full experience in any terminal — with any editor, on any OS. Windows, macOS and Linux.
Unified sessions: start in the editor, pick up in the terminal — same conversation, same context.
Install k4tron
Choose where you want to work and get started in minutes.
VS Code extension
Bring k4tron into your editor with a conversation feed, diffs and approvals.
Or install from the terminal:
- Open k4tron in the VS Code Marketplace.
- Click Install and open the k4tron panel in VS Code.
- Connect your account, open a session and send your first task.
Requires VS Code 1.85 or newer.
CLI in the terminal
Use k4tron with any editor, directly from your project's terminal.
Start in the terminal:
- In your project's terminal, run npx k4tron — no global install needed.
- Or install the command with npm install -g k4tron and run k4tron.
- Connect your account, open a session and send your first task.
Requires Node.js 20 or newer.
How it works
Install a client
Add the extension to VS Code, or install the CLI in your terminal.
Generate your connection code
On first launch, click “Generate connection code”. Your account is born with trial credits — no card.
Paste it and go
Paste the code, open a new session and send your first task.
Why k4tron
Simple clients — in the editor and the terminal — with all the intelligence on the platform.
Zero setup
No API key, no keys on your machine, no settings panel. Paste a connection code and you're in.
Pick the tier, not the model
Lite, Basic, Standard, Premium. You pick the power; the platform routes the right model — and improves it without you touching a thing.
Transparent usage
Cost shows up in credits, in real time — per message and per session. No provider pricing tables.
Multi-agent
In swarm mode, k4tron fans subtasks out to parallel background agents — heavy work, done faster.
Skills
Ready-made playbooks: fix a bug, refactor, migrate, review, test, commit — each one knows when it's done.
Any machine
One connection code per device, revocable anytime. Switch machines whenever you want.
A tier for every task
You pick; the platform handles the model behind it.
Lite
Minimum cost — trivial tasks and quick checks.
Basic
defaultBalanced — great cost/benefit for most cases.
Standard
Daily work — feature dev, review and debugging.
Premium
Frontier capability — architecture, large refactors, critical tasks.
Ask by name
Playbooks the agent follows from start to “done”.
