Autonomous AI coding agents aim to cut developer overhead by running independently in the cloud, performing tasks like coding, testing and refactoring without human oversight. Commercial services such as GitHub Copilot Workspace or Replit Agent charge $10–$20 per month per user. This article demonstrates building a comparable autonomous coding agent for just $5.70 per month, leveraging open-source tools agent-deck and orca, on a basic cloud virtual machine.
The process begins with setting up a lightweight Ubuntu virtual machine on a budget cloud platform. DigitalOcean and Vultr are examples of such providers. A minimal Ubuntu 22.04 droplet with one CPU, one gigabyte of RAM, and 25 GB of storage is provisioned at around $5 per month. After logging into the machine via SSH, the system is updated and basic tools like Git, curl, Python, and Docker are installed.
Next, the agent-deck open-source terminal session manager is installed. This software provides a tmux-like interface and can manage multiple AI agent sessions. The orca CLI runtime, another essential component, is then installed. orca supports plugin-style workflows and integrates seamlessly with agent-deck.
To enable autonomous operations, the agent is configured to push changes to a GitHub or GitLab repository automatically. SSH key authentication is set up for secure access, and the OpenAI API key is securely exported to the environment. The agent is then configured to write code, run tests, and commit improvements based on prompts given by the agent-deck session.
Security measures include restricting shell access to SSH keys only, using a dedicated GitHub deploy key with write-only permissions, and running the agent under a non-root user. Cron jobs are set up to restart the agent daily, ensuring its continuous operation.
In summary, building an autonomous AI coding agent for under $6 per month is achievable with open-source tools agent-deck and orca, significantly undercutting commercial alternatives. This setup empowers developers by automating coding, testing, and code management tasks, potentially increasing productivity and reducing operational costs.
