Claude Code, Codex CLI, and similar tools are AI coding agents. They are powerful, but they are usually meant to be used interactively by a developer who plans the task, drives the tool, reviews the output, fixes problems, and keeps the task moving. Vroni replaces the developer in that workflow, not the coding agent. You assign the task and Vroni runs the process. Under the hood, Vroni uses state-of-the-art AI coding agents, including tools like Claude Code and Codex CLI, inside a larger engineering workflow for planning, implementation, checks, failure repair, and follow-up requests. You get the benefit of those coding agents plus a system built to deliver finished software.
