OpenAI Codex
OpenAI's open-source coding agent
Codex reads your repository, edits files and runs commands inside a sandbox that limits what it can touch, asking before it steps outside. For unattended work, codex exec runs a task from a single prompt with no interactive screen - the natural fit for a server, a cron job or a CI step.
Light on its own; VPS IFW 2, with 4 GB and 2 vCPU, leaves room for your build and test suite.
