Can I run multiple AI agents at once?

Yes. You can run Claude Code, Aider, and other tools simultaneously in different tmux windows. The Pro plan (2 GB RAM) comfortably handles 2-3 agents. For more, use the Business plan (4 GB RAM).

Do I need to bring my own API keys?

Yes. Each AI tool uses its own API key. You bring your Anthropic key for Claude Code, your OpenAI key for Codex, etc. We provide the server infrastructure, you control the AI billing.

A VPS built for AI coding agents

Q: What AI coding agents can I run?

Any AI coding agent that runs on Linux. Claude Code, OpenAI Codex CLI, Aider, Continue, and any other tool. You have full root access to install whatever you need.

Q: What is an AI agent VPS?

An AI agent VPS is a virtual private server optimized for running AI coding assistants. It provides persistent sessions, enough RAM for AI tools, browser terminal access, and managed infrastructure so you focus on coding, not server administration.

Run Claude Code, Codex, Aider, or any AI coding tool on a managed server that never sleeps. Browser terminal, SSH, persistent storage. Your agents work 24/7.

Why AI agents need a dedicated server

AI coding agents are different from traditional development tools. They run long tasks autonomously — refactoring codebases, building full applications, running test suites. These tasks take minutes or hours, not seconds.

Running these agents on your laptop means:

Close your laptop = agent dies, context lost
Wi-Fi drops for 10 seconds = SSH disconnects, session gone
Can not check progress from another device
Your laptop fans spin, battery drains, machine slows down

A dedicated AI agent server solves all of these. Your agents run on hardware in a datacenter with 24/7 power and network. You connect when you want, disconnect when you want. The work continues either way.
