Pricing
The K2 app is free — you pay only for the network that reaches your machines and, soon, for servers we run for you. Your API keys, your token spend: K2 never marks up model usage.
The software
K2
The desktop app and the always-on daemon. Fair Source, free for individuals and businesses, free to self-host — on your Mac, a Linux box, or a Raspberry Pi.
K2 Connect
Domains
A stable, end-to-end-encrypted your-name.k2.dev address for a machine you run. It's your agent's contact address — agents on other servers message it peer to peer — and it's how the K2 Companion on your phone reaches your server from anywhere. No port-forwarding, no static IP.
Single
- ✓One your-name.k2.dev subdomain — your agent's contact address
- ✓Cross-server agent messaging (k2 msg agent::host)
- ✓Secure tunnel, E2E encryption
- ✓Web, desktop & mobile Companion (Android/Apple)
Pro
- ✓Everything in Single
- ✓API calls to your server (/v1)
- ✓Nested subdomains — *.your-name.k2.dev
- ✓Per-port targets for other services
- ✓Create & manage from the k2 CLI
K2 Cloud
Servers
Don't have a machine to leave on? We'll run one for you: a K2 server provisioned in one click, paired with a k2.dev subdomain — one you already own, or a new one added at checkout — your owner account ready, and updates managed from your dashboard.

Summit
12+ cores, custom builds — sized to your workload with a human in the loop.
Every server is reached through its k2.dev subdomain, so one is required: pair a subdomain you already own, or add a new one to the same checkout at its normal price ($2.99/mo Single, $7.99/mo Pro). API access requires a Pro subdomain. Bring your own model API keys on every plan — token spend goes to your provider, never through us.
