Overview
Codebuff is positioned as an AI coding agent that developers can run directly in the terminal, supporting installation via npm and connection to multiple models. Users mainly start tasks through the command-line interface, and the agent automatically calls sub-agents to divide work across file selection, code generation, and review steps. The product offers web, CLI, and desktop versions. In free mode, it can be used for several hours per day, after which ads are shown. Compared with single-agent tools, it differentiates itself through role-based task splitting and freedom of model choice, making it suitable for individual developers already using Claude Code or Codex but looking to reduce costs.
One-line summary
Codebuff is a terminal AI coding agent that is free to use by showing text ads, with its core selling point being that it splits coding tasks across multiple specialized sub-agents such as file selection, editing, and review.
What people use it for
Users use it to generate concrete feature code in Unity projects, such as weapon effects, menu interfaces, and character switching; when quotas for other paid tools run out, users switch to it to continue finishing the remaining coding tasks.
Best for
Developers, engineering teams, and technical leads
How it works
It typically starts by reading context in the IDE, terminal, or project environment, then the Agent plans steps, executes commands or modifies files, and the user checks the results.
