What you get

Everything you'd build with tmux, cron and SSH, already done.

It keeps running

The K2 daemon outlives every window. Idle agents sleep and wake when a message arrives.

Scheduled jobs

Heartbeats: daily, weekly, monthly, yearly or hourly. No window needed, and a history of who changed what.

Missed jobs catch up

If the machine was off at 2 a.m., the job runs when it wakes.

Where it runs

Your box, or ours.

Your own server.A Linux machine, a VPS or an office box. Free. Reach it over K2 Connect or your own private network, such as Tailscale.
K2 Cloud.We run the server for you. From $14.99/mo, plus an address to reach it from anywhere.
Your Mac.Great to start. The agents run while it's awake.
Honest limits

What to know first.

Your AI plan

K2 runs the official CLIs under the sign-in you give them. For always-on use, an API key or a bot account with spend limits is safer than a personal plan. Check your provider's terms.

Not a sandbox

Agents on one server run as the same OS user. Use a separate server or VM if you need isolation.

Platforms

Linux and macOS (Apple Silicon). No Windows build today.

FAQ

Questions people ask

Can I run Claude Code on a VPS or Linux server?
Yes. K2 has a headless Linux daemon. Install it on your server, sign in to Claude Code there once, and hire agents. They keep running after you disconnect.
How do scheduled tasks work?
Heartbeats. Give an agent a daily, weekly, monthly or hourly job with its own instructions. It runs with no window open, and a job missed while the machine was off fires when it wakes.
Can I use it from my phone?
Yes. K2 Companion (iOS and Android) shows your agents' chats and project chats, lets you message them, and lets you answer the questions they ask you.
How do I reach my server from outside?
Either K2 Connect, which gives the server an address like your-name.k2.dev (from $2.99/mo), or your own private network, such as Tailscale.
Don't want to run a server?
Rent one: K2 Cloud servers start at $14.99/mo, plus an address for reaching it from anywhere.
