# K2

> K2 by Alakazam Labs is agent server software: a desktop app plus an always-on daemon that runs AI coding agents (Claude Code, Codex, Gemini CLI, Copilot, Grok, Cursor, Goose, and others) in persistent terminal sessions. Every project workspace is a persistent agent you can message, share with teammates, and reach remotely.

Key facts:

- Every project workspace is a persistent agent; message it from the CLI with `k2 talk`.
- Multiplayer presence: see who is connected to your server, with viewer and edit roles.
- K2 Connect gives your server a your-name.k2.dev subdomain over an E2E-encrypted tunnel; the relay cannot read session contents. Plans: Single $2.99/month, Pro $7.99/month (Pro adds /v1 API access to your server, nested subdomains, and per-port targets).
- HTTP API (/v1): host-sessions spawn live agent terminals that answer via `k2 respond` (bring-your-own LLM key per API key). Dedicated servers can also expose sandboxed microVM sessions. Docs: https://k2.dev/docs/api
- Mobile companion app (iOS and Android) connects to your own server through K2 Connect.
- Licensed Fair Source (FSL-1.1-Apache-2.0). Source: https://github.com/Alakazam-211/K2
- Download today (https://k2.dev/download): macOS (Apple Silicon) desktop app, signed and notarized; Windows x64 installer in alpha (still working through bugs); Linux desktop app in beta (.deb, .rpm, and .AppImage for x86_64 — the app needs the k2-daemon running for full autostart); signed headless Linux daemon binaries (x86_64 and aarch64) for servers.
- K2 Cloud hosted servers: Standard $29.99/month. A server does not include a subdomain, but requires one (the tunnel is the only access path) — at purchase you pair a subdomain you already own ($29.99/month total) or add a new one to the same checkout at its normal price (with Single: $32.98/month total; with Pro: $37.98/month total). API access requires a Pro subdomain. Dedicated $99.99/month coming soon.
